A Comprehesive Guide To Autoflowering Cannabis Seeds

Everything you need to know about Autoflower Cannibus Seeds from growing to harvesting!

About Feminized Cannabis Seeds and Autoflowering Cannabis Seeds

in the beginning, back in the 1990s we resisted the movement to feminized Cannabis seeds. At that time much of our customer base were happy with dioecious plants and in many cases were making their own Cannabis seeds from our base strain Cannabis seeds.

It wasn’t the idea of feminizing Cannabis seeds per se but rather the feminization process at the time and unfortunately still true to this day, led to hermaphroditic plants from the resultant seeds. None-the-less the market was speaking to us and a lot of growers now wanted feminized Cannabis seeds. We decided if we could find a way to feminize seeds that did not produce hermaphroditic plants we would sell feminized Cannabis seeds. We developed our own Cannabis feminization process that absolutely did not produce hermaphroditic Cannabis plants from the resultant seeds; indeed for years and to this day people who want to use the old feminization process to make their own feminized Cannabis seeds complain to us that they can’t make our feminized Cannabis strains turn into hermaphrodite plants. It is beyond rare that a grower can induce enough stress to cause our plants produce hermaphrodite Cannabis flowers.
Our first feminized Cannabis strains were Bubba Kush, OG Kush, Chemdawg and later East Coast Sour Diesel, Trainwreck and G-13. We were the first in the world to offer these benchmark Cannabis strains in seed form. We are proud to still carry these benchmark Cannabis strains unchanged and unadulterated.

Now to Auto-flowering Cannabis plants and seeds.
As with feminized Cannabis strains we resisted introducing auto flowering Cannabis strains. We looked around and test grew many Autoflower Cannabis plants and all we saw were dishonest advertisements that showed close ups of Auto-flowering Cannabis plants that gave no indication of the low yield of most auto flowering Cannabis plants; so generally speaking, the yield wasn’t good enough to make our list.
We also sampled many, many Auto-flowering Cannabis strains and none were of sufficient potency to make our list.

After a time we developed Iranian Autoflower Cannabis and Cannabis seeds. Finally a Cannabis plant we felt was of superb potency and respectable yield; so Iranian Autoflower was the first Auto-flowering Cannabis good enough to be on our list and has been a solid leader in auto-flowering seed sales for us for about ten years now. More recently we were able to produce Auto-flowering OG Kush Cannabis and Cannabis seeds that we named Whiplash OG and that stuff is flying off the shelf with customers coming back for more year after year.

Unlocking the Potential of Autoflower Seeds: A Comprehensive Guide

A Brief introduction of the concept of autoflowering cannabis seeds.

Autoflowering cannabis seeds are a unique type of cannabis seed known for their ability to automatically switch from the vegetative growth phase to the flowering phase based on their age, rather than relying on changes in light cycles. This distinctive trait makes them popular among growers for their rapid growth, compact size, and adaptability to various light conditions. Autoflowering seeds have a shorter life cycle, often maturing and ready for harvest in as little as 8 to 12 weeks from germination, making them a preferred choice for those seeking quick yields and flexibility in cultivation.

The significance of autoflower seeds in the cannabis industry.

Autoflower seeds hold significant importance in the cannabis industry for several compelling reasons:

Rapid Growth and Shorter Harvest Time: Autoflowering cannabis plants have a much quicker life cycle compared to traditional photoperiod strains.

Growing Autoflower Cannabis 

A detailed Cultivation Guide for Autoflowering Cannabis

  1. Germination and Seedling Stage:

Start with high-quality autoflower seeds from a reputable source.Germinate seeds using the paper towel method or by placing them in a small container with a moist growing medium. Maintain a temperature of around 70-75°F (21-24°C) and a humidity level of 70-80%.Once seedlings have emerged, transplant them into their final pots or growing containers, preferably  with a well-draining potting mix.

  1. Light Requirements:

Autoflowering cannabis thrives with at least 18-20 hours of light per day during the vegetative stage. Indoors, use high-quality LED or HPS grow lights. Maintain a distance between the lights and the canopy to prevent light burn and heat stress. Some growers use a 24-hour light cycle, as autoflower plants are less sensitive to light stress. However, providing a brief dark period can help conserve energy and reduce costs.

  1. Nutrient and Watering Needs:

Use a balanced, pH-neutral soil mix or a hydroponic system suitable for autoflowers.Start with half-strength nutrient solutions and gradually increase as plants grow. Autoflowers are sensitive to nutrient burn, so monitor carefully.Water when the top inch (2.5 cm) of soil feels dry. Overwatering can lead to root rot, so allow for proper drainage.Measure and adjust pH levels of water and nutrient solutions to maintain a pH of around 6.0-6.5.

  1. Pruning and Training Techniques:

Autoflowers have a limited vegetative stage, so avoid aggressive pruning. Instead, focus on low-stress training (LST) and defoliation techniques to maximize light penetration and airflow. Use soft plant ties or garden twine to gently bend and secure branches to expose lower growth sites to light.Tuck fan leaves instead of removing them to minimize stress.

Common Pitfalls and Troubleshooting Tips:

Overfeeding: Be cautious with nutrients; overfeeding can lead to nutrient burn and stunted growth. Start with a light nutrient regimen.

Overwatering: Ensure proper drainage and let the soil dry slightly between watering. Yellowing or drooping leaves can be signs of overwatering.

Light Burn: Monitor the distance between lights and plants to prevent light burn, which can cause bleached or damaged leaves.

pH Imbalance: Maintain proper pH levels in your water and nutrient solutions. pH fluctuations can affect nutrient uptake.

Pests and Diseases: Regularly inspect plants for pests like spider mites or aphids. Treat promptly with organic pesticides if necessary.

Stress: Autoflowers are sensitive to stress. Avoid sudden changes in light, temperature, or humidity.

Note: Autoflowering strains are generally more forgiving than photoperiod strains but still require attention to detail. Experimentation and observation are key to perfecting your cultivation techniques. With proper care and attention, you can successfully cultivate autoflowering cannabis plants and enjoy their fast growth and harvest times.

Maximizing Yields with Autoflower Plants

Maximizing yields with autoflowering cannabis plants requires a combination of proper care, strategic techniques, and attention to detail. Here are tips and strategies to optimize your autoflower harvest:

  1. Start with Quality Genetics: Choose high-quality autoflowering strains from reputable breeders. Select strains known for their yield potential and desired characteristics.
  2. Optimize Lighting: Provide adequate light during the vegetative and flowering stages. Autoflowers benefit from 18-20 hours of daylight during the vegetative stage and 12-14 hours during flowering. Use high-intensity LED, HPS, or CMH grow lights to ensure sufficient light intensity. Keep light fixtures at the appropriate distance to avoid light burn or stress.
  3. Low-Stress Training (LST): LST involves gently bending and securing branches to encourage lateral growth and create an even canopy.Use soft plant ties or garden twine to bend branches and expose lower growth sites to light. LST is particularly effective in optimizing light distribution and increasing the number of bud sites.
  4. High-Stress Training (HST): HST techniques, such as topping or fimming, can be employed sparingly with autoflowers. These methods involve more aggressive pruning or bending. Proceed with caution when using HST techniques, as autoflowers have a limited vegetative stage, and excessive stress can slow growth or reduce yields.
  5. Proper Nutrient Management: Start with a well-balanced nutrient regimen and monitor plant response closely. Avoid overfeeding, as autoflowers are sensitive to nutrient burn. Begin with half-strength nutrients and gradually increase as plants mature. Use a pH meter to ensure nutrient solutions remain within the optimal range (around 6.0-6.5 pH).
  6. Careful Pruning and Defoliation: Prune and defoliate sparingly to maintain airflow and light penetration. Remove only large, shading fan leaves and avoid aggressive pruning.Tuck leaves or branches instead of removing them entirely to minimize stress.
  7. Maintain Environmental Conditions: Keep temperature and humidity levels within the ideal range for cannabis cultivation (around 70-85°F or 21-30°C and 40-60% humidity). Ensure proper ventilation and airflow to prevent mold and mildew.
  8. Avoid Stress and Shock: Autoflowers are sensitive to stress and can recover more slowly than photoperiod strains. Avoid sudden changes in environmental conditions, including temperature, humidity, and lighting.
  9. Adequate Container Size: Use appropriately sized containers to accommodate the root system. A larger container allows for more root growth and better nutrient uptake.
  10. Timing and Planning: Autoflowers have a predetermined life cycle. Plan your growth cycle to ensure they receive the maximum amount of light and nutrients during their limited vegetative phase.
  11. Harvest at the Right Time: Pay attention to trichome development and the maturity of your plants. Harvest when trichomes are cloudy or amber, depending on your desired effect.

12. Monitor for Pests and Diseases: Regularly inspect plants for pests and diseases, as these can reduce yields. Use organic pest control methods if necessary. Remember that every strain may respond differently to various techniques, so it’s essential to observe and adapt your approach based on the specific needs and characteristics of your autoflowering cannabis plants. With careful planning and attention, you can maximize your autoflower yields and enjoy high-quality cannabis.

Harvesting and Curing Autoflower Buds

Harvesting and curing autoflowering cannabis buds is a crucial process to ensure the highest quality, potency, and flavor. Here’s a step-by-step guide:

The Signs of Readiness for Your Harvest

Trichome Color: The most reliable indicator of harvest readiness is the color of the trichomes (the small, resinous glands on the buds). Use a magnifying glass to inspect the trichomes:

Clear: Harvesting at this stage will result in a more energetic and psychoactive effect.

Cloudy: Harvesting when trichomes are mostly cloudy will produce a balanced high, with both cerebral and body effects.

Amber: If you prefer a more sedative, relaxing effect, wait until some trichomes turn amber (usually around 10-20% amber).

Pistil Color: Another indicator is the color of the pistils (hairs) on the buds. When pistils start turning from white to brown or orange, it’s a sign that the plant is nearing maturity.

Calyx Swelling: As the buds mature, the calyxes (the small pods that encase the seeds) will swell, making the buds appear denser.

Overall Appearance: Buds should be well-formed, plump, and resinous, with no signs of mold or disease.

The Harvesting Process

Harvest in the morning or when the lights come on to capture the plant’s peak terpene and cannabinoid levels. Use clean, sterilized scissors or pruning shears to cut the branches. Trim away any large fan leaves. Hang the branches upside down in a dark, cool, and well-ventilated space with a temperature of about 60-70°F (15-21°C) and a humidity level of around 45-55%.

Trimming: Once the branches are dry and the buds feel crisp on the outside (usually in about 5-10 days), it’s time to trim. Trim away excess leaves and sugar leaves (small leaves covered in trichomes) that don’t have many trichomes. Leave some sugar leaves for a smoother smoke.Handle buds gently to avoid damaging trichomes.

Drying: Continue to dry the trimmed buds in a dark, cool, and well-ventilated space for another 5-10 days, or until the smaller stems snap when bent. Use a hygrometer to monitor humidity levels; they should stabilize around 50%. Keep the drying area free from light, pests, and mold.

Curing: Place the dried buds in airtight glass jars, filling them about 2/3 full to allow air circulation. Store the jars in a cool, dark place with a consistent temperature of about 60-70°F (15-21°C). Open the jars daily for the first two weeks to “burp” them, releasing excess moisture and preventing mold. Gradually reduce burping frequency over several weeks. Properly cured buds improve in flavor and aroma over time. Aim for a curing period of at least 2-4 weeks, but longer curing (up to several months) can further enhance the quality.

Storing: Store cured buds in a cool, dark, and airtight container. Mason jars work well. Keep them away from light, heat, and humidity, which can degrade cannabinoids and terpenes. Use humidity packs or control devices to maintain ideal moisture levels (around 58-62%).

Properly harvested, dried, trimmed, and cured autoflowering cannabis buds will provide a smoother, more flavorful, and potent smoking or vaping experience. Be patient, as curing is a critical
