How long do Autoflowering Cannabis plants spend in flower?
Autoflowering cannabis plants typically spend between 7 to 10 weeks in the flowering stage. The exact duration can vary based on the strain and the specific growing conditions. Some strains may even take up to 12 weeks to fully mature.
It’s important to remember that unlike photoperiod cannabis strains, autoflowers switch from the vegetative stage to the flowering stage based on age rather than changes in light cycle.
This means that the total lifespan of an autoflowering plant, from seed to harvest, is generally from 8 to 12 weeks.
To determine when your autoflowering plant is ready to harvest, you’ll want to look at the trichomes (the tiny, mushroom-shaped glands on the buds and leaves).
When a majority of the trichomes have transitioned from clear to a milky white colour, and some have turned amber, it’s usually a good time to harvest. A magnifying glass can be helpful in inspecting the trichomes.
Why are Autoflowering Cannabis Plants so popular?
Autoflowering cannabis strains have several characteristics that make them attractive to both novice and experienced growers:
1. Fast Growth Cycle: Autoflowering plants typically have a much faster growth cycle than traditional photoperiod plants, going from seed to harvest in as little as 8-12 weeks. This allows for multiple harvests within the same timeframe that a traditional strain would produce just one.
2. No Light Cycle Changes Required: Autoflower strains switch from the vegetative stage to the flowering stage based on their age, not changes in light cycle. This makes them easier to grow, especially for beginners, because you don’t have to worry about adjusting the light schedule to induce flowering.
3. Smaller Size: Autoflowers are generally smaller than photoperiod plants, which makes them a good choice for indoor grows or any situation where space might be limited.
4. Resilience: Autoflowers are often hardier and more resistant to pests and diseases compared to traditional cannabis strains, thanks to their ruderalis genetics. This can make them a bit more forgiving to grow.
5. Variety: As autoflowers have gained in popularity, breeders have introduced a wide variety of strains, allowing growers to choose from autoflowering versions of many of their favourite cannabis strains.
6. Multiple Harvests: Because of their quick life cycle, growers can harvest several crops of autoflowering plants in the time that it takes for traditional photoperiod plants to produce a single harvest. This can be especially beneficial in outdoor grows, where you’re not limited to a single harvest in the fall.
Remember, while autoflowers offer many advantages, they also have their limitations.
For example, they generally produce less yield per plant than photoperiod strains, and they don’t typically respond well to plant training techniques that involve high-stress methods, such as topping.
Do Autoflowers grow while flowering?
Yes, autoflowering cannabis plants do continue to grow while they are flowering, but the nature of their growth changes. This period of continued growth during the early flowering phase is often referred to as the “stretch” phase.
During the vegetative stage, an autoflowering cannabis plant focuses on building its structure, growing leaves and branches. When it transitions into the flowering stage, it doesn’t stop growing completely. It continues to grow, but the growth is mostly focused on developing the flowers or buds.
In the first few weeks of flowering, the plant may continue to grow in height, often significantly, which is why it’s called the “stretch” phase. After that, most of the plant’s energy is directed towards bud development. The plant may still grow a bit taller during this time, but the pace of height growth slows down substantially.
It’s important to note that while autoflowers continue to grow during flowering, they are not like photoperiod strains which can be kept in vegetative growth indefinitely under the right light conditions. Autoflowers have a set life cycle and will automatically shift from vegetative growth to flowering after a certain period of time, regardless of light conditions.
What are the drawbacks of Autoflowering Cannabis?
While autoflowering cannabis strains have many advantages, they also come with certain drawbacks. Here are a few:
1. Smaller Yields: Due to their smaller size and shorter growth cycle, autoflowers generally yield less per plant than photoperiod strains. However, the possibility of multiple harvests in a year can help balance this out.
2. Less Potency: Historically, autoflowering strains were less potent than their photoperiod counterparts. However, modern breeding techniques have significantly closed this gap, and many autoflowering strains now have THC levels comparable to photoperiod strains.
3. Limited Cloning Potential: Autoflowers aren’t ideal for cloning. Because their life cycle is determined by age rather than light cycle, a clone will be the same age as the mother plant and will therefore flower at around the same time, resulting in a very small plant with a minimal yield.
4. Less Responsive to Training: High-stress training techniques like topping or FIMing can be harmful to autoflowering plants because they don’t have the time to recover that photoperiod plants do. Low-stress training methods can be used, but growers have less time and fewer opportunities to train the plant due to the short vegetative stage.
5. No Vegetative Stage Control: With photoperiod plants, growers can extend or shorten the vegetative stage as needed by adjusting the light schedule. This is not possible with autoflowering plants, which can be a drawback if a grower needs more flexibility.
6. Cost: Autoflower seeds can often be more expensive than photoperiod seeds, which can be a deterrent for some growers.
It’s important for growers to weigh these potential drawbacks against the advantages of autoflowering strains when deciding which type of cannabis to grow.
Can a feminized Autoflower turn male?
Feminized seeds, including autoflowering ones, are bred to produce only female plants, so they should not naturally turn into males. However, under certain circumstances, a feminized plant can develop male characteristics through a process called hermaphroditism.
Stress is the main cause that can lead a feminized plant to become a hermaphrodite. This could be due to environmental factors such as drastic changes in light cycle or spectrum, temperature fluctuations, over or under watering, nutrient deficiencies or excesses, physical damage, or disease.
When a female plant undergoes significant stress, it may start to produce male flowers in an effort to self-pollinate and ensure the survival of its genetics.
It’s important to note that not all stress will cause a plant to “hermie.” It generally takes a significant amount of stress, and some strains are more prone to hermaphroditism than others due to their genetic predisposition.
If a feminized plant does start to develop male flowers, it’s crucial to remove these as soon as possible to prevent them from pollinating the female flowers.
If pollination does occur, the female flowers will then produce seeds, reducing the overall yield of consumable cannabis buds – not an ideal situation.
To avoid hermaphroditism, try to provide a stable growing environment with minimal stress. Regularly check your plants for signs of stress or the development of male flowers. If you do find male flowers, remove them immediately to protect the rest of your plants.
Are Autoflowers better for beginners?
Autoflowering cannabis strains can indeed be a good choice for beginners for several reasons:
1. Simplicity: Autoflowers switch from the vegetative stage to the flowering stage based on their age, not changes in light cycle. This makes them easier to grow, especially for beginners, because you don’t have to worry about adjusting the light schedule to induce flowering.
2. Fast Growth Cycle: Autoflowering plants typically have a much faster growth cycle than traditional photoperiod plants, going from seed to harvest in as little as 8-12 weeks. This can be a good thing for beginners because it allows for quicker feedback on your growing practices.
3. Small Size: Autoflowers are generally smaller than photoperiod plants, which makes them a good choice for indoor grows or any situation where space might be limited. For beginners who are starting with a small setup, this can be very beneficial.
4. Resilience: Autoflowers are often hardier and more resistant to pests and diseases compared to traditional cannabis strains. This can make them more forgiving for beginners who are still developing their growing skills.
5. Variety: As autoflowers have skyrocketed in popularity, breeders have introduced a wide variety of strains. This means beginners can choose from an ever growing range of options to find a strain that matches their specific needs and preferences.
Remember, while autoflowers offer many advantages for beginners, they also have their limitations.
For example, they generally produce less yield per plant than photoperiod strains, and they don’t generally respond well to plant training techniques that involve high-stress methods, such as topping.
But,for many beginners (and indeed experienced growers) the benefits outweigh these limitations, making autoflowers a great starting point for learning to grow cannabis.
How strong are Autoflowers?
The strength, or potency, of autoflowering cannabis strains can vary widely depending on their specific genetics. Historically, autoflowering strains were less potent than photoperiod strains.
This is because autoflowering strains were originally bred with Cannabis ruderalis, a wild type of cannabis that is known for its autoflowering characteristics but has lower levels of THC, the main psychoactive compound in cannabis.
However, over time, breeders have worked to increase the potency of autoflowering strains by crossbreeding them with high-THC strains. As a result, many modern autoflowering strains have THC levels that are comparable to those of photoperiod strains, some even reaching up to 20-25% THC or more.
In addition to THC, cannabis contains other cannabinoids like CBD and terpenes, which also contribute to the plant’s overall effects.
Some autoflowering strains have been bred to be high in CBD and lower in THC, which can be beneficial for medical users or those who want the health benefits of cannabis without a strong psychoactive effect.
As always, the effects of any cannabis strain can vary depending on individual tolerance, dose, method of consumption, and other factors. It’s also important to remember that while THC content can be an indicator of potency, it doesn’t tell the whole story.
Other factors, such as the presence of other cannabinoids and terpenes, can also influence the overall effects and therapeutic benefits of a strain.
How much does 1 Autoflower plant yield?
The yield of an autoflowering cannabis plant can vary significantly depending on the strain and growing conditions. On average, you might expect to yield between 1 to 2 ounces (28 to 56 grams) per plant when grown under optimal conditions indoors.
Some larger autoflowering strains or expertly grown plants can yield up to 6 ounces (170 grams) or more per plant, but these are exceptional cases.
Several factors can influence the yield of your autoflowering cannabis plants:
1. Strain: Some autoflowering strains are simply bred to be more productive than others. Be sure to research the expected yield of your specific strain.
2. Light: Autoflowers need ample light to produce a healthy yield. Using high-quality grow lights and providing 18-24 hours of light per day can help maximize yield.
3. Nutrients: Proper feeding is crucial to the growth and yield of your plant. A balanced cannabis-specific nutrient regimen will help ensure your plants get the nutrients they need at the right time.
4. Environment: Conditions such as temperature, humidity, and airflow can significantly affect your plant’s health and yield. Optimal conditions can vary depending on the stage of growth.
5. Training: Techniques such as low-stress training (LST) can help increase yield by exposing more of the plant to light.
6. Pot Size: A larger pot allows for a larger root system, which can contribute to a larger plant and a higher yield. However, autoflowers typically don’t require as large a pot as photoperiod strains.
7. Growing Medium: The choice of soil versus hydroponics can also impact the final yield, with hydroponics often leading to larger yields if managed correctly.
Remember that these are just averages and your results may vary. For the best results, it’s important to carefully manage your growing conditions and respond to your plant’s needs throughout its life cycle.
How long do autoflowering cannabis plants grow?
Autoflowering cannabis plants typically have a shorter lifespan than traditional photoperiod strains. From seed to harvest, autoflowers generally take between 8 to 12 weeks. This timeframe includes both the vegetative and flowering stages.
Here’s a general timeline:
1. Seedling Stage (1-2 weeks): During the first couple of weeks, your plant is a seedling. It will develop its first set of leaves and begin to look more like a cannabis plant.
2. Vegetative Stage (2-4 weeks): Once the seedling stage is complete, your plant will enter the vegetative stage. During this stage, the plant focuses on growing bigger and taller, developing its structure.
3. Flowering Stage (5-10 weeks): After about 3-5 weeks, your autoflower will automatically transition to the flowering stage. This is when your plant starts to produce buds. The flowering stage can last anywhere from 5 to 10 weeks, depending on the strain and growing conditions.
Remember that these timelines can vary based on the strain and growing conditions. To determine when your autoflowering plant is ready to harvest, you’ll want to look at the trichomes (the tiny, mushroom-shaped glands on the buds and leaves).
When a majority of the trichomes have transitioned from clear to a milky white color, and some have turned amber, it’s usually a good time to harvest.
How many hours a day do Autoflowers need?
Autoflowering cannabis strains are not dependent on light cycles to transition between the vegetative and flowering stages, as traditional photoperiod strains are. This gives you more flexibility in terms of how many hours of light per day you provide.
That said, a common light schedule for autoflowers is 18 hours of light and 6 hours of darkness per day (18/6 schedule) for the entire lifecycle of the plant. This provides a good balance between giving the plants plenty of light for photosynthesis and growth, and allowing a period of darkness each day for the plant to rest.
Some growers even choose to provide 20 hours of light and 4 hours of darkness (20/4 schedule), or even 24 hours of continuous light, in order to maximize photosynthesis and growth.
However, there is some debate among growers about whether a period of darkness is beneficial for the plant, and whether the additional energy cost of providing more light results in a proportionate increase in yield.
In general, more light will tend to result in greater growth and higher yields, up to a point. However, it’s also important to ensure that the light is not so intense that it causes light burn or other forms of stress to the plant.
Monitoring your plants for signs of stress and adjusting your light setup accordingly is a key part of successful cannabis cultivation.
Can I harvest the top half of my Autoflower plant?
In theory, you could selectively harvest parts of your autoflowering cannabis plant, but it’s not typically recommended. Here’s why:
Autoflowering cannabis plants are different from photoperiod cannabis plants. Autoflowers have a set lifecycle which is not influenced by changes in light schedule. They start flowering based on their age, not based on changes in the light cycle.
Harvesting only the top half of an autoflowering plant won’t trigger the remaining part of the plant to keep growing or produce more buds, because it’s not the plant’s natural response.
Once an autoflower starts to flower, it will keep doing so until its lifecycle ends. Also, any stress on the plant – such as harvesting part of it – can potentially reduce the health and yield of the remaining buds.
As always, it’s important to monitor your plants closely and respond to their specific needs, as every strain and every grow environment can have different requirements.
Is it good to top an autoflower plant?
Topping, which involves cutting off the top of the cannabis plant to encourage it to grow more branches and thus more flower sites, is a common technique used with photoperiod cannabis strains.
However, it’s generally not recommended for autoflowering strains.
Here’s why:
1. Short Life Cycle: Autoflowering cannabis plants have a shorter life cycle than photoperiod strains. Topping is a high-stress training technique that plants need time to recover from. Autoflowers may not have enough time to fully recover before they start flowering.
2. Potential Yield Loss: Due to their short life cycle, any stress, including the stress from topping, can potentially result in a smaller yield. Stressed plants tend to focus more on recovery than growth and bud production.
3. Size: Autoflowers are generally smaller than photoperiod plants, and topping may reduce the size of the plant even further.
While topping is generally not recommended for autoflowers, some growers have successfully used this technique with careful timing and attentive care to the plant’s recovery.
However, for most growers, especially those new to cannabis cultivation, it’s safer to stick to low-stress training techniques, such as LST (Low Stress Training), bending and securing branches to expose more of the plant to light.
Remember, every plant is unique and will respond to stress differently. What works well for one plant might not work as well for another, even if they are the same strain. It’s always important to monitor your plants closely and adjust your care based on their individual responses.
How much soil do you need for Autoflowers?
The amount of soil needed for autoflowering cannabis plants depends on the size of the pot you’re using, which in turn should be appropriate for the size of the plant you’re growing.
Autoflowers are generally smaller than photoperiod strains and thus usually require less space for root growth. A pot that holds about 2 to 3 gallons (7-11 liters) of soil is often sufficient for most autoflowering strains. This size allows enough room for the plant to develop a good root system but isn’t so large that it becomes inefficient for water and nutrient use.
Remember, a larger pot will require more soil, but it will also hold more water, which can make watering less frequent but potentially more challenging.
Overwatering can be a risk if the pot is too large for the plant’s needs. On the other hand, a smaller pot dries out faster and might need more frequent watering but reduces the risk of overwatering.
Some growers choose to use even smaller pots for autoflowers, such as 1-gallon pots, while others may use larger pots of 5 gallons. The best pot size can depend on the specific strain, the plant’s growth rate, the growing medium, and the grower’s personal preferences and growing style.
In any case, the soil you use should be well-draining and rich in organic matter. Cannabis plants prefer a slightly acidic soil pH, usually between 6.0 and 7.0. Many growers opt for cannabis-specific soil mixes, which are designed to provide the right nutrient balance for cannabis plants.
What is the best soil for Autoflowers?
When growing autoflowering cannabis plants, the choice of soil can greatly influence the overall health and productivity of your plants. Here are a few key characteristics to look for in a soil:
1. Well-draining: Cannabis plants don’t like to have “wet feet.” The soil should have good drainage to prevent water-logging and root rot. This often means looking for a soil that contains perlite, vermiculite, or sand to help improve drainage.
2. Rich in organic matter: Cannabis plants thrive in nutrient-rich soil. Look for a soil that contains plenty of organic matter, such as compost or worm castings. These materials will provide a slow and steady supply of nutrients to your plants as they grow.
3. Correct pH: Cannabis prefers a slightly acidic soil pH, typically between 6.0 and 7.0. Many commercial cannabis soils are pre-buffered to maintain this ideal pH range.
4. Light and airy: The soil should be light and airy to allow the roots to breathe and grow easily. Again, ingredients like perlite and vermiculite can help create this kind of texture.
Several commercial soil brands are well-suited for growing autoflowering cannabis.
These include Fox Farms Ocean Forest Soil and Roots Organic Original Potting Soil. Both of these soils contain a good mix of nutrients and are well-draining, which are important for cannabis plants.
However, some growers prefer to make their own soil mix to have more control over the exact composition. A basic recipe might include components like peat moss or coco coir for the base, compost or worm castings for nutrients, and perlite or vermiculite for drainage.
No matter which soil you choose, remember that it will likely need to be supplemented with additional nutrients as your plants grow, since cannabis has high nutrient needs and can deplete the nutrients in the soil over time. Always monitor your plants for signs of nutrient deficiencies or excesses, and adjust your feeding regimen accordingly.
What is the strongest autoflower?
Here are a few of the strongest autoflowering strains from Barney’s Farm’s catalogue, based on their THC content:
1. Purple Punch Auto: This strain is an autoflowering version of the popular Purple Punch. It’s known for its high THC levels, reaching up to 24%, and its grape and berry flavors.
2. Gorilla Glue Auto: Barney’s Farm’s version of Gorilla Glue Auto is a potent strain with THC levels that can reach around 25%. It’s known for its resinous buds and balanced effects.
3. Wedding Cake Auto: Wedding Cake Auto is a potent autoflowering strain with THC levels of up to 25%. It’s a version of the popular Wedding Cake strain, renowned for its sweet, vanilla flavor.
4. Runtz Auto: Runtz Auto is an autoflowering version of the original Runtz, boasting high THC levels of approximately 27%. It’s celebrated for its sweet, fruity flavor profile.
5. Dos Si Dos Auto: Dos Si Dos Auto from Barney’s Farm is a potent strain with THC levels reaching around 22%. This strain is a variation of the original Dos Si Dos, known for its intense, calming effects.
Please note that the actual potency can vary based on the specific plant phenotype and growing conditions. Also, THC content is not the sole measure of a strain’s potency – other factors, such as the presence of other cannabinoids and terpenes, can significantly influence the overall effects and experience.
Why are my Autoflowers so tall?
Autoflower cannabis plants are known for their relatively small size compared to photoperiod strains, but several factors can lead to taller-than-expected growth:
1. Genetics: The genetics of your autoflowering plant play a significant role in its growth pattern. Some autoflower strains have been bred with Sativa strains, which are naturally taller, to produce autoflowers that can grow taller than the average.
2. Lighting: Autoflowering plants need ample light to grow properly. However, if the light source is too far from the plant, it may cause the plant to stretch or grow taller in an attempt to get closer to the light source. This phenomenon is known as “stretching.” You might want to adjust the distance between your lights and plants if this is happening.
3. Temperature and Humidity: Environmental conditions such as temperature and humidity can also affect plant height. High temperatures and low humidity levels, especially in the seedling stage, can cause plants to stretch.
4. Nutrients: Overfeeding can sometimes cause rapid, unnatural growth in plants, leading them to be taller. Always follow a proper feeding schedule and adjust based on your plant’s specific needs.
5. Improper Training: Techniques like Low Stress Training (LST) are used to control the height and shape of the plant. If these techniques are not applied or are implemented incorrectly, autoflowers can grow taller than expected.
To manage the height of your autoflowering plants, you can manipulate their growing conditions or use training techniques.
However, remember that each plant is unique and what works for one may not work for another. Always monitor your plants closely to understand their specific needs.
Will Autoflowers produce seeds?
Autoflowering cannabis plants, like all cannabis plants, have the potential to produce seeds if they are fertilized. However, most growers aim to avoid this as the presence of seeds can reduce the overall quality and quantity of the usable bud.
Here’s how it works:
Feminized Autoflowers – Most autoflower seeds sold are feminized, meaning they are bred to produce only female plants. Female plants are the ones that produce the large, resinous buds that are harvested for use. If these female plants are not exposed to male pollen (either from a male plant or a hermaphrodite plant), they will not produce seeds and will instead put all their energy into producing more resin and cannabinoids.
Non-Feminized Autoflowers – If you’re growing from non-feminized autoflower seeds, you’ll get a mix of male and female plants. In this case, you would need to identify and remove the male plants before they release pollen in order to prevent your female plants from being fertilized and producing seeds.
Stress-Induced Hermaphroditism – Sometimes, a female plant can become a hermaphrodite (developing both male and female reproductive parts) as a response to stress. If this occurs, the plant may self-pollinate and produce seeds. To prevent this, it’s important to provide a stable growing environment and avoid high-stress techniques.
So, while autoflowering plants can produce seeds, most growers aim to prevent this from happening to maximize the quality and quantity of their harvest. If you want to produce seeds for further propagation, you would need to intentionally pollinate your female plants.
How often do Autoflowers need nutrients?
Autoflowering cannabis plants typically need to be fed nutrients once or twice a week, but this can depend on a variety of factors including the stage of growth, the size of the plant, the type of growing medium used, and the specific nutrient regimen you’re following.
Here’s a general guide:
Seedling Stage (1-2 weeks): At this stage, your autoflowering plants typically won’t need any additional nutrients if you’re using a quality soil with a good amount of organic matter. The seedlings are very delicate at this stage and can easily be burned by excess nutrients.
Vegetative Stage (2-4 weeks): As your plants enter the vegetative stage, they will start to require more nutrients to support their rapid growth.
This is a good time to start introducing a balanced nutrient solution, but it’s still important to start with a lower dose to avoid nutrient burn. You can gradually increase the nutrient dosage as your plants grow and show that they can handle it.
Flowering Stage (5-10 weeks): During the flowering stage, your plants’ nutrient needs will change. They will require less nitrogen and more phosphorus and potassium to support bud development. At this stage, you’ll typically need to feed your plants a nutrient solution specifically designed for the flowering stage once or twice a week.
Do keep in mind that these are just general guidelines, and the exact feeding schedule can vary based on your specific growing conditions and the needs of your plants.
Always pay close attention to your plants and adjust your feeding regimen as needed based on their appearance and growth. Signs of nutrient deficiencies or excesses can include yellowing leaves, brown spots, slow growth, and other abnormalities.
Are Autoflowers more expensive?
The cost of autoflowering cannabis seeds can vary depending on the strain, the seed bank, and the quality of the seeds.
Generally, autoflowering seeds can be slightly more expensive than regular photoperiod seeds, but this is not always the case.
This higher cost can be attributed to several factors:
1. Breeding Process: Autoflowering strains are created through a complex breeding process that includes introducing genetics from Cannabis ruderalis, a variety of cannabis that naturally autoflowers. This process can take time and resources, which can contribute to a higher cost.
2. Shorter Grow Cycle: Autoflowering plants have a shorter grow cycle compared to photoperiod plants. This means that growers can have multiple harvests in the time it would take for a photoperiod strain to reach harvest. The potential for a faster return on investment can make autoflowering seeds more valuable.
3. Ease of Growth: Autoflowering strains are generally easier to grow than photoperiod strains, as they don’t require a change in light schedule to trigger flowering. This makes them a popular choice for less experienced growers, which can drive up demand and price.
While the upfront cost of autoflowering seeds may be higher, many growers find that the benefits, such as the shorter grow cycle and ease of growth, make them a worthwhile investment for many.
Do Autoflowers need sleep?
Autoflowering cannabis plants, like all plants, have a natural rhythm that includes periods of activity and rest. However, autoflowering strains do not require a traditional dark period in the same way that photoperiod (non-autoflowering) cannabis plants do.
Photoperiod cannabis plants rely on specific light cycles to trigger their vegetative and flowering stages. They typically require a 12 hours light, 12 hours dark schedule to induce flowering. The dark period, or “sleep,” is crucial for these plants as it allows them to rest and prepare for the next day’s light exposure.
Autoflowering plants, on the other hand, are not dependent on light cycles to trigger their growth stags. This is due to their genetics, which include Cannabis ruderalis, a subspecies adapted to regions with long days in the summer where the sun might not set for a significant amount of time. Therefore, autoflowers can technically grow and flower under 24 hours of light without a “sleep” period.
However, some growers still prefer to give autoflowers a period of darkness each day, such as a 20 hours light, 4 hours dark schedule. The reasoning behind this is that it may help the plant’s metabolic processes, and can save on electricity costs.
In summary, while autoflowers do not “need” a sleep period in the same way photoperiod plants do, a period of darkness can still be beneficial for them.
As with many aspects of cultivation, the optimal light schedule can depend on the specific strain and growing conditions. It’s always a good idea to do research and experimentation to find what works best for your specific situation.
What’s better Autoflower or regular?
Whether autoflowering or regular (also known as photoperiod) cannabis strains are “better” really depends on the specific needs and constraints of the grower. Both types have their advantages and disadvantages.
Here are some factors to consider:
Autoflowering Strains
• Speed: Autoflowers typically have a much quicker growth cycle than regular strains. They can go from seed to harvest in as little as 8-10 weeks. This can be advantageous for growers looking for a quick turnaround.
• Size: Autoflowers are generally smaller than regular plants, which can be beneficial for indoor or stealth grows where space is limited.
• Lighting: Autoflowers are not dependent on light cycles to trigger their growth stages. This means they can be grown under constant light, which can simplify the growing process.
• Predictability: Because autoflowers automatically switch from vegetative growth to flowering after a certain amount of time, there’s less chance for a grower to make errors in timing.
Photoperiod (Regular) Strains
• Potency and Yield: Regular strains often have the potential for higher THC levels and larger yields than autoflowers. However, this can greatly depend on the specific strain and the skill of the grower.
• Flexibility: Regular plants can be kept in the vegetative stage for as long as the grower wants, allowing for techniques like training, pruning, and cloning that are not always suitable for autoflowers.
• Selection: There is a wider variety of regular strains available compared to autoflowering strains, giving growers more options to find a strain that suits their needs.
In summary, neither type is inherently “better” than the other. The best choice depends on the specific needs and constraints of the grower. Factors such as growing space, desired turnaround time, experience level, and personal preferences can all play a role in deciding whether autoflowering or regular strains are the best choice.
Can I grow Autoflower and Regular plants together?
Yes, you can grow autoflowering and regular (photoperiod) cannabis plants together, but it requires careful planning and management to ensure that both types of plants receive the appropriate light schedules they need.
Autoflowers are not dependent on light cycles to trigger their growth stages—they will automatically transition from the vegetative stage to the flowering stage after a certain amount of time, regardless of the light schedule.
Because of this, they can technically be grown under continuous light, or a light schedule with a significant amount of daily light, such as 20 hours on and 4 hours off (20/4).
Regular cannabis plants, on the other hand, require specific light cycles to trigger their vegetative and flowering stages. They typically require a light schedule with equal amounts of light and dark, such as 12 hours on and 12 hours off (12/12), to induce flowering.
If you want to grow both types of plants in the same space, you could consider the following options:
1. Use the autoflower light schedule for both types of plants: This would involve keeping the light schedule at something like 18/6 or 20/4 for the entire grow. The autoflowers will grow and flower as normal under this schedule. The regular plants will stay in their vegetative stage under this schedule, and will only start flowering if you switch to a 12/12 schedule. This might be a good option if you want to keep the regular plants in a prolonged vegetative state for training or cloning.
2. Start the autoflowers later: If you want the autoflowers and regular plants to flower at the same time, you could start the regular plants first, and then start the autoflowers later. The idea is to time it so that the autoflowers start flowering at the same time that you switch the light schedule to 12/12 for the regular plants.
Remember, the success of growing both types together in the same space will require careful planning and management. It’s also important to note that the optimal light schedule can depend on the specific strain and growing conditions, so it’s always a good idea to do some research and experimentation to find what works best for your situation.
What should I feed my Autoflower?
Feeding autoflowering cannabis plants involves providing them with the necessary nutrients they need to grow and flower. Autoflowers typically need the same basic nutrients as regular cannabis plants: nitrogen (N), phosphorus (P), and potassium (K), often referred to as the NPK ratio.
These are considered macronutrients and are needed in larger amounts. Other necessary nutrients, required in smaller amounts, include calcium, magnesium, and a range of trace elements.
However, autoflowers generally don’t require as much feeding as regular cannabis plants due to their smaller size and faster growth cycle.
Overfeeding can lead to nutrient burn, so it’s important to start with a light feeding schedule and gradually increase the nutrients as needed.
Here’s a general guide on what to feed your autoflower at different stages of its life:
1. Seedling Stage: Young seedlings have enough stored nutrients to sustain them for the first week or two. During this stage, they usually only need water and a light source.
2. Vegetative Stage: Once the plant has developed a few sets of leaves, it enters the vegetative stage and begins to require additional nutrients. During this stage, autoflowers typically require higher levels of nitrogen (N), which promotes healthy leaf and stem growth.
3. Flowering Stage: When the plant starts to flower, its nutrient needs will shift. It will require less nitrogen (N) and more phosphorus (P) and potassium (K). Phosphorus and potassium are essential for bud development.
4. Late Flowering/Before Harvest: During the last couple of weeks before harvest, it’s common to flush the plants with plain water. This helps to remove any excess nutrients and can improve the taste and quality of the final product.
Remember, these are general guidelines and the specific nutrient needs can vary based on the strain and growing conditions. It’s also important to monitor your plants for signs of nutrient deficiencies or excesses, and adjust your feeding schedule as necessary.
Always follow the instructions provided by your nutrient manufacturer, as concentrations can vary between products.
It’s worth noting that using a high-quality soil or growing medium can also provide your plants with many of the nutrients they need, especially in the early stages of growth. In this case, supplemental feeding might not be necessary until later in the plant’s life.
Lastly, pH plays a crucial role in nutrient uptake. Cannabis prefers a slightly acidic pH, around 6.0-7.0 in soil or 5.5-6.5 in hydroponics. Regularly checking and adjusting the pH of your water and nutrient solution can help ensure your plants are able to effectively absorb the nutrients they need
Are Autos harder to grow?
Autoflowering cannabis strains are generally considered easier to grow than photoperiod (regular) strains, making them a popular choice for beginners. Here’s why:
1. Simplified Light Schedule: Autoflowers are not dependent on light cycles to trigger their vegetative and flowering stages. They will automatically transition from vegetative growth to flowering after a certain amount of time, regardless of the light schedule. This simplifies the growing process as you don’t need to worry about changing the light schedule to induce flowering.
2. Faster Growth Cycle: Autoflowers typically have a much quicker growth cycle than regular strains, going from seed to harvest in as little as 8-10 weeks. This not only means a quicker turnaround, but also less time for things to go wrong.
3. Smaller Size: Autoflowers are generally smaller than regular cannabis plants, which can make them easier to manage, especially for indoor growers with limited space.
However, there are a few challenges unique to autoflowers that growers should be aware of:
1. Less Room for Error: Due to their shorter lifespan, autoflowers have less time to recover if something goes wrong, such as a pest infestation or nutrient problem. This means you’ll need to monitor your plants closely and address any issues promptly.
2. Limited Training Opportunities: Because autoflowers transition to flowering on their own timeline, there is less opportunity for plant training techniques that rely on controlling the vegetative stage, such as topping or main-lining.
3. Potentially Lower Yields and Potency: Autoflowers can produce less yield than their photoperiod counterparts, and some autoflowering strains may also have slightly lower THC content. However, the gap has been narrowing with the development of new autoflowering strains.
In summary, while autoflowers have certain characteristics that can make them easier to grow, successful cultivation still requires attention to detail, careful monitoring, and an understanding of basic plant care principles.
How do I get big buds on my Autoflower?
Maximizing bud size in autoflowering cannabis plants involves a combination of providing optimal growing conditions and proper care throughout the plant’s life cycle. Here are some tips to help increase the size and quality of your autoflower buds:
1. Choose the Right Strain: Genetics plays a big role in the potential size and potency of your buds. Some autoflowering strains are bred to produce larger buds than others. Do your research to find a strain that is known for producing big buds.
2. Optimal Lighting: Proper lighting is crucial for cannabis growth. Autoflowers generally do well under 18-24 hours of light per day. Make sure your plants have access to plenty of bright, but not scorching, light to encourage photosynthesis and growth.
3. Proper Nutrients: Cannabis plants need the right nutrients to grow big buds. During the flowering stage, they need less nitrogen and more phosphorus and potassium. Using a bloom or flowering fertilizer can help provide these nutrients.
4. Monitor pH: The pH level of your water and nutrient solution can affect the plant’s ability to absorb nutrients. Cannabis prefers a slightly acidic pH, around 6.0-7.0 in soil or 5.5-6.5 in hydroponics.
5. Control Temperature and Humidity: Cannabis plants like a certain climate. During the flowering stage, aim for temperatures around 70-80°F (20-26°C) and a relative humidity around 40-50%.
6. Pruning and Training: While some high-stress training methods are not recommended for autoflowers due to their short life cycle, low-stress training (LST) and selective leaf pruning can help expose more bud sites to light, promoting bigger buds.
7. Avoid Overwatering: Overwatering is a common mistake that can lead to root problems and stunt bud development. Water deeply, but infrequently, and only when the top inch or so of the soil is dry to the touch.
8. Proper Air Circulation: Good air circulation is important to prevent mold and pests, and to ensure your plants get enough carbon dioxide for photosynthesis. Use fans to circulate air in indoor grows, but avoid pointing them directly at the plants, which can cause wind burn.
9. Flushing Before Harvest: Flushing the plants with plain water a week or two before harvest can help remove any excess nutrients and improve the taste and quality of your buds.
Remember, growing cannabis is as much an art as it is a science. Each plant is unique and may require different care. It’s always a good idea to monitor your plants closely, adjust your care practices as needed, and experiment to find what works best for you and your plants.
How often should I water my Autoflowers?
The frequency at which you should water your autoflowering cannabis plants can depend on a variety of factors, including the stage of growth, the size of the plant, the medium in which you’re growing, the size of the pot, the environment, and even the particular strain. However, here are some general guidelines to follow:
Seedling Stage: Young seedlings do not require a lot of water. In fact, overwatering at this stage can be detrimental. Seedlings typically prefer a consistently moist (but not waterlogged) environment. Depending on your growing medium and environmental conditions, this might mean lightly watering or misting the seedlings once a day or every other day.
Vegetative Stage: As your plants grow and their root systems develop, they will start to require more water. However, it’s still important to avoid overwatering, which can lead to root problems like root rot. A good rule of thumb for this stage is to water deeply, until you see some water coming out of the bottom of the pot, and then wait to water again until the top inch or so of the soil is dry to the touch.
Flowering Stage: Watering needs can increase during the flowering stage as the plant is working hard to produce buds. However, the same principle applies: water deeply, and then wait until the top inch of the soil is dry before watering again.
In addition to these guidelines, here are a few more tips:
• Check the weight of the pot: Lifting the pot is a good way to judge whether it’s time to water again. After watering, the pot will feel heavy. As the plant uses up the water, the pot will start to feel lighter. With experience, you can learn to judge when it’s time to water again based on the weight of the pot.
• Watch for signs of overwatering or underwatering: If your plant’s leaves are wilting or turning yellow, it might be a sign of overwatering. On the other hand, if the leaves are drooping but perk up shortly after watering, it might be a sign of underwatering.
• Be aware of your growing environment: Factors such as temperature, humidity, and the intensity of your lights can all affect how quickly your plants use water. For example, plants will typically use water more quickly in a hot, dry environment compared to a cool, humid one.
Remember, these are just guidelines, and the exact watering schedule that works best for your autoflowers can depend on a variety of factors. Monitoring your plants closely and learning to recognize their needs is the key to successful watering.
How do you plant Autoflower seeds directly in soil?
Planting autoflower seeds directly in soil can be a straightforward process. Here are the steps to do it:
1. Prepare Your Pot: Autoflowers do not like to be transplanted, so it’s best to plant the seeds directly into their final growing pot. A 3-5 gallon pot is often a good size for autoflowers. Fill your pot with a good quality soil or potting mix. A light, well-draining soil is usually best. Some growers choose to mix in some perlite for added drainage.
2. Water the Soil: Water the soil until it’s thoroughly moist, but not waterlogged. It’s usually best to use pH balanced water (pH 6.0-7.0) for this.
3. Plant the Seed: Make a small hole in the soil with your finger or a pencil, about 0.5-1 inch deep. Place the autoflower seed in the hole, pointy end down. Lightly cover the seed with soil. Do not pack the soil down over the seed, as this can make it harder for the seedling to break through the surface.
4. Maintain Moist Conditions: Keep the soil moist until the seedling sprouts. This usually takes a few days to a week. You can lightly mist the soil with water if it starts to dry out. Some growers choose to cover the pot with a plastic bag or dome to keep the humidity high, but if you do this, make sure to remove the cover once the seedling sprouts to prevent mold growth.
5. Provide Light: Once the seedling sprouts, it will need access to light. Autoflowers can handle a lot of light, so aim for 18-24 hours of light per day.
6. Monitor and Care for Your Seedling: Monitor your seedling closely as it grows. Keep the soil moist, but be careful not to overwater. Once the plant has developed a few sets of leaves, it will start to need additional nutrients, so start a light feeding schedule according to the nutrient manufacturer’s recommendations.
Remember, while autoflowers are generally hardy and easy to grow, they are also fast growers with a short life cycle, which means they have less time to recover from problems.
Therefore, it’s important to monitor your plants closely, address any issues promptly, and take care to avoid common mistakes like overwatering or overfeeding.
Can you grow Autoflowers in winter?
Yes, you can grow autoflowers in winter, but there are some challenges and considerations to keep in mind.
1. Indoor Growing: If you’re growing indoors, you can grow autoflowers at any time of the year, including in winter. Indoor growing allows you to control the environment, so you can provide optimal light, temperature, and humidity conditions for your plants regardless of what’s happening outside.
2. Outdoor Growing: If you’re growing outdoors in winter, it can be more challenging depending on your climate. Autoflowers generally prefer temperatures in the range of 70-80°F (20-26°C), and they can start to experience problems if temperatures drop below 50°F (10°C) or so. They also need plenty of light to grow, which can be in short supply during the winter months, especially in higher latitudes. That being said, if you live in a climate with mild winters and plenty of winter sunlight, it might be possible to grow autoflowers outdoors in winter.
3. Greenhouse Growing: A greenhouse can be a good compromise for winter growing. A well-insulated greenhouse can help protect your plants from cold temperatures, and it can also extend the daylight hours by capturing and holding onto sunlight.
If you decide to grow autoflowers in winter, choose strains that are known for their hardiness and resistance to cold. Monitor your plants closely for signs of cold stress, which can include slow growth, purpling of the leaves, and in extreme cases, frost damage.
Remember, cannabis is a resilient plant and can adapt to a range of conditions. However, providing optimal growing conditions will help ensure that your plants can grow to their full potential and produce a good yield.
Do Autoflowers like intense light?
Yes, autoflowering cannabis plants do typically enjoy intense light. They have a much shorter vegetative period than traditional photoperiod cannabis plants, and during this time they need as much light as possible to grow and develop before they start flowering.
Autoflower plants can tolerate up to 24 hours of light per day, although a schedule of 18-20 hours of light and 4-6 hours of darkness is quite common and may help the plant to rest and metabolize nutrients.
When it comes to light intensity, it’s important to strike the right balance. Too little light can lead to weak, spindly plants and reduced yields. On the other hand, too much light, especially in combination with high temperatures, can cause light burn or heat stress.
As a rule of thumb, indoor growers using LED lights can place them 18-24 inches away from the top of the plants. If you’re using more intense lights, like HPS or MH bulbs, they may need to be placed further away to prevent heat stress.
Always monitor your plants closely for signs of light or heat stress, which can include yellowing or “bleaching” of the leaves, curling leaf edges, or a general wilting or drooping appearance.
In general, autoflowers are quite hardy and adaptable, but they can still benefit from a well-managed environment. Balancing light intensity with proper temperature and humidity control will help ensure that your autoflowers can grow and produce to their full potential.
Can Autoflowers go back to veg?
No, autoflowering cannabis plants cannot revert back to the vegetative state once they have started flowering. This is due to their genetic heritage.
Autoflowers contain genetics from Cannabis ruderalis, a variety of cannabis that originated in harsh climates with irregular and short periods of daylight.
As a survival mechanism, these plants evolved to flower based on age, rather than light cycle. This trait has been bred into autoflowering cannabis strains, which means they will automatically start flowering after a certain period of vegetative growth, regardless of the light schedule.
Once an autoflower starts flowering, it is on a set course to mature and produce buds, and it cannot be reverted back to the vegetative state. This is different from photoperiod cannabis plants, which can potentially be reverted back to the vegetative state by changing the light cycle back to a vegetative light schedule (typically 18-24 hours of light per day).
This is one of the reasons why it’s generally not recommended to use high-stress training techniques like topping or supercropping with autoflowers.
These techniques can cause significant stress and recovery time, and because autoflowers have such a short life cycle, they don’t have much time to recover before they start flowering. It’s better to use low-stress training techniques that can be applied gradually over time, without causing too much stress or disruption to the plant’s growth.
Can I trim an Autoflower during flowering?
Yes, you can trim or prune autoflowering cannabis plants during flowering, but it should be done carefully and sparingly. Because autoflowers have a shorter life cycle than photoperiod plants, they have less time to recover from stress.
Excessive pruning can potentially stress the plant and reduce your final yield.
That said, strategic pruning can be beneficial for airflow and light penetration, especially if the plant is particularly bushy. Here are some tips if you decide to trim during flowering:
1. Be Selective: Only trim leaves that are yellow, dying, or blocking light to bud sites. Healthy leaves are an important part of the plant’s photosynthesis process and contribute to bud development, so avoid removing them unless necessary.
2. Avoid Over-Trimming: Remember, every leaf you remove is a part of the plant’s energy production system. Over-trimming can stress the plant and potentially reduce your final yield.
3. Trim Gradually: If you decide to trim, do so gradually over time rather than all at once to avoid causing too much stress to the plant.
4. Clean Tools: Always use clean, sharp scissors or pruning shears to make clean cuts and reduce the risk of infection or disease.
5. Monitor the Plant: After trimming, monitor the plant closely for any signs of stress or disease.
In general, low-stress training (LST) techniques are often recommended over pruning for autoflowers. LST involves gently bending and tying down branches to change the plant’s shape and expose more bud sites to the light, without causing significant stress to the plant.
This can be a more effective way to increase yield in autoflowers, as it doesn’t involve removing parts of the plant.
Can you reuse Autoflower soil?
Yes, you can reuse soil from a previous autoflower crop, but it requires some additional steps to ensure the soil is healthy and nutrient-rich for your next crop. Here’s a general process you can follow:
1. Remove Old Roots: Start by removing any large root masses or other plant material from the soil. These can decompose and cause problems with pests or disease.
2. Compost: Add the used soil to a compost pile, if you have one. Composting helps to break down any remaining roots and plant material and can replenish the soil with nutrients.
3. Replenish Nutrients: If you’re not composting the soil, you’ll need to replenish the nutrients that the previous plants used up. You can do this by adding amendments like compost, worm castings, bone meal, or other organic matter.
4. Sterilize (Optional): Some growers choose to sterilize the soil to kill any pests or pathogens. This can be done by baking the soil in the oven at a low temperature (around 200°F or 90°C) for about 30 minutes. Be aware, though, that this can also kill beneficial microbes in the soil.
5. Test pH: Before reusing the soil, test the pH to make sure it’s in the correct range for cannabis (typically around 6.0-7.0 for soil). If the pH is off, you may need to adjust it using lime (to raise pH) or sulfur (to lower pH).
6. Rest: Allow the soil to rest for a few weeks before planting your next crop. This gives the amendments time to break down and become available to your plants.
Reusing soil can be a cost-effective and environmentally friendly practice, but it does require some extra work compared to using fresh soil. If you decide to reuse your soil, monitor your plants closely for any signs of nutrient deficiencies or other problems. If problems arise, you may need to adjust your soil amendments or consider using fresh soil.
What is the best soil for Autoflowers (UK)?
The best soil for autoflowers in the UK can depend on a few factors such as your specific growing conditions and the requirements of the autoflower strain you’re growing.
However, some soils that are commonly recommended for autoflowers in the UK include Plant Magic Soil, Biobizz Allmix, and John Innes.
Remember, regardless of the brand of soil you choose, it’s important to ensure that it has good drainage and aeration, and that it contains the necessary nutrients for your plants.
You might also consider adding some amendments to your soil, such as compost or worm castings, to further enhance its nutrient content.
Always monitor your plants closely for any signs of nutrient deficiencies or other problems, and adjust your soil or feeding regimen as necessary.
There are also ready made soils especially for autoflowers available such as Living Soils.
How do I take care of my Autoflower?
Taking care of autoflowering cannabis plants involves a few key steps. Here’s a basic guide:
1. Choose the Right Strain: Different autoflower strains have different growth characteristics and care requirements. Choose a strain that’s suitable for your growing conditions and experience level.
2. Use a Suitable Growing Medium: Autoflowers can be grown in soil, coco coir, or hydroponic systems. If you’re using soil, make sure it’s light and well-draining. Autoflowers generally prefer slightly acidic pH levels (6.0-7.0 for soil, 5.5-6.5 for hydroponics or coco).
3. Provide Plenty of Light: Autoflowers need a lot of light to grow and produce well. They can handle up to 24 hours of light per day, although a schedule of 18-20 hours of light and 4-6 hours of darkness is quite common.
4. Water Carefully: Autoflowers are susceptible to overwatering. It’s generally better to water deeply and less frequently, rather than little and often. Always allow the top inch of soil to dry out before watering again.
5. Feed Appropriately: Start with a light feeding schedule and adjust based on your plant’s needs. Autoflowers don’t need as much nutrients as photoperiod plants, and they can be sensitive to overfeeding.
6. Consider Low-Stress Training: Low-stress training techniques like bending and tying down branchescan help expose more bud sites to the light and increase yields, without causing too much stress to the plant.
7. Monitor and Adjust: Keep a close eye on your plants and adjust your care regimen as necessary. Look out for any signs of nutrient deficiencies, pests, or disease, and address any issues promptly.
Remember, while autoflowers are generally hardy and easy to grow, they also have a short life cycle, which means they have less time to recover from problems. Taking care to provide optimal growing conditions and address any issues promptly can help ensure a successful harvest.
What week should I stop feeding my Autoflower?
The exact timing can vary depending on the specific strain you’re growing and its individual needs, but a common rule of thumb is to stop feeding your autoflowering plants with nutrients about two weeks before you expect to harvest.
This two-week period is often referred to as the “flushing” phase. During this time, you should water your plants as usual but without adding any nutrients.
The idea behind flushing is to allow the plant to use up any remaining nutrients in the soil and in its tissues. This can help to improve the taste and quality of the final buds by reducing harshness that can be caused by leftover nutrients.
Remember, this is a general guideline and may not apply to all situations. For instance, if your plant is showing signs of a nutrient deficiency during these last couple weeks, it might be beneficial to continue feeding with a reduced nutrient solution.
Always monitor your plants closely and adjust your care regimen as needed. Signs that your plant is ready for harvest include most of the pistils changing from white to brown and the trichomes (the small, crystal-like structures on the buds) changing from clear to a milky white color. A jeweler’s loupe or a small microscope can be very helpful for checking the color of the trichomes.
Do you need lights for Autoflowers?
Yes, lights are a critical component for growing autoflowering cannabis plants. Like all green plants, cannabis uses light for photosynthesis, the process by which it converts light energy into chemical energy to fuel its growth.
Autoflowers have a unique advantage over traditional photoperiod cannabis plants in that they are not dependent on changes in light cycle to trigger flowering. This means you can maintain a consistent light schedule throughout their entire life cycle.
For indoor growing, autoflowers can receive 18-24 hours of light per day. Many growers opt for a 20/4 schedule (20 hours of light, 4 hours of dark) to give plants a bit of rest and save on energy.
In terms of the type of lights to use, there are several options, including compact fluorescent lights (CFLs), high-intensity discharge (HID) lights, and light-emitting diodes (LEDs). LEDs are often favored for their efficiency and full-spectrum light output, but the best choice will depend on your specific setup and budget.
For outdoor growing, autoflowers can be planted at any time of the year as long as temperatures are suitable. They will flower automatically after a certain period of time, regardless of daylight hours.
However, they will generally perform best when they can receive at least 8-10 hours of direct sunlight per day. In regions with shorter daylight hours or lower light intensity, growers may supplement with additional lighting.
In all cases, providing adequate light is key to healthy growth and optimal yields with autoflowering cannabis plants.
How can you tell if a Autoflower is male or female?
Most autoflowering cannabis seeds that you can buy are feminized, meaning they have been bred to only produce female plants. Female plants are the ones that produce the buds that are harvested for their high cannabinoid content.
However, it’s still possible (though unlikely) to end up with a male or hermaphrodite plant, so it’s important to know how to identify the sex of your plants.
Here’s how you can tell if an autoflower is male or female:
Female Plants
• Female plants develop small, hair-like structures called pistils. These will appear at the nodes (where the branches meet the stem) and they are often white or light-colored.
• When female plants start flowering, they will form clusters of these pistils, which will develop into buds over time.
Male Plants
• Male plants develop small, ball-like structures called pollen sacs. These will also appear at the nodes, but they look very different from pistils.
• If these pollen sacs are allowed to mature, they will burst open and release pollen, which can fertilize female plants and cause them to produce seeds.
Hermaphrodite Plants
• Hermaphrodite plants have both male and female reproductive structures, meaning they can produce both pistils and pollen sacs.
• Hermaphroditism can be caused by genetics or by stress, such as extreme temperatures or inconsistent light schedules.
If you identify any male or hermaphrodite plants in your garden, it’s usually best to remove them as soon as possible to prevent them from fertilizing your female plants.
Unless you’re intending to breed your own seeds, fertilization will detract from cannabinoid production and result in lower-quality buds.
If you’re growing from feminized autoflower seeds and you see what look like pollen sacs, it’s worth considering if your plants might be under stress and showing hermaphroditic tendencies.
If this is the case, you’ll need to identify and correct the source of the stress to prevent further issues
What do Autoflowers look like before harvest?
Just like regular cannabis plants, autoflowers will show certain signs when they are ready to be harvested. Here’s what to look for:
1. Pistil Color: Pistils are the hair-like structures on the buds. Early in the flowering stage, these will be white or light-colored. As the plant matures, the pistils will begin to darken and curl inwards. When around 60-70% of the pistils have turned brown or red and curled in, this is often a sign that the plant is ready for harvest.
2. Trichome Color: Trichomes are the small, crystal-like structures on the buds and leaves of the plant. These contain the plant’s cannabinoids and terpenes. You’ll need a magnifying glass or jeweler’s loupe to see them clearly. Initially, trichomes are clear.
As the plant matures, they turn a milky white color. When about 70-90% of the trichomes are milky white and the rest are amber, the plant is usually at peak THC content and is ready to be harvested. If you want a more sedative effect, you can wait until more of the trichomes have turned amber, which indicates that some of the THC has converted to CBN.
3. Leaf Color: Towards the end of the plant’s life cycle, the leaves will start to yellow and die off as the plant redirects nutrients towards the buds. This is a normal part of the plant’s maturation process and can be a sign that harvest time is approaching.
4. Swelling of the Buds: As the plant matures, the buds will swell and become denser. This is another sign that the plant is nearing its harvest time.
Remember, these are general guidelines and the exact timing can vary depending on the specific strain you’re growing and your personal preferences. Always monitor your plants closely and adjust your harvest time as needed.
How long do Autoflowers need to veg?
Autoflowering cannabis plants typically have a shorter vegetative stage compared to regular, photoperiod cannabis plants. The vegetative stage is the period of growth between the seedling stage and the flowering stage when the plant focuses on developing its structure and foliage.
For autoflowers, the vegetative stage usually lasts about 2-4 weeks from germination. However, the exact length can vary depending on the specific strain and the growing conditions.
After this short vegetative period, autoflowering plants will automatically begin to flower, regardless of the light schedule.
It’s important to note that unlike photoperiod plants, you can’t extend the vegetative stage of autoflowers by manipulating the light schedule.
This is because autoflowers are genetically programmed to start flowering after a certain period of time.
This can be a benefit, as it makes the growth cycle more predictable, but it also means that autoflowers have less time to recover from stress or damage incurred during the vegetative stage. As such, they may require more careful handling and management during this stage.
Do Autoflowers need nitrogen during flower?
Yes, autoflowering cannabis plants do still require nitrogen during the flowering stage, but in lower amounts than during the vegetative phase. Nitrogen is an essential nutrient for cannabis plants, and it plays a crucial role in photosynthesis and the production of proteins and amino acids.
During the vegetative phase, cannabis plants require higher levels of nitrogen to support rapid growth and the development of foliage.
As plants transition into the flowering phase, their nitrogen requirements decrease, and their need for other nutrients, particularly phosphorus and potassium, increases. These nutrients support bud development and overall plant health during flowering.
Overfeeding nitrogen during flowering can cause problems, as it can inhibit the uptake of other nutrients and potentially reduce bud production. It can also lead to nitrogen toxicity, which can cause the leaves to become dark green and potentially curl or become damaged.
If you’re using a pre-formulated cannabis nutrient solution, it will likely have different recommended mixtures for the vegetative and flowering stages to accommodate these changing nutrient needs.
Always follow the manufacturer’s recommendations, and monitor your plants closely for signs of nutrient deficiencies or excesses, adjusting your feeding regimen as needed.
What is the average yield of an autoflower indoors?
The yield of an indoor autoflowering cannabis plant is influenced by a variety of factors, which can lead to significant variation in yield from one plant to the next. Here are some of the key factors:
1. Strain: Different autoflowering strains have different growth characteristics, including different potential yields. Some strains are bred for maximum productivity and can yield more than others.
2. Lighting: The amount and quality of light that your plants receive is a key factor in determining their yield. More light generally leads to larger yields (up to a point), as long as the light is not so intense that it damages the plants. Also, light spectrum can affect plant development and yield, with full spectrum lights generally considered optimal.
3. Nutrients: Cannabis plants need a range of nutrients to grow and produce buds. Providing the right balance of nutrients can help maximize your yield, while nutrient deficiencies or excesses can reduce yield.
4. Growing Medium: The medium in which you grow your plants can also affect their yield. Some mediums may hold water and nutrients better than others, or provide better aeration to the roots.
5. Care: The care that you provide to your plants throughout their life cycle, including watering, pruning, and protecting against pests and diseases, can significantly affect their final yield.
6. Environment: Factors such as temperature and humidity can also influence yield. Cannabis plants generally prefer a relatively warm and humid environment during the vegetative stage, and a cooler and less humid environment during the flowering stage.
Given all these factors, while the average yield of an indoor autoflowering cannabis plant might typically range from 50 to 120 grams per plant, it’s quite possible for a well-cared-for plant grown under optimal conditions to exceed this range. Conversely, a plant that is not provided with optimal conditions or care may yield less.
