How to Grow Autoflowering Strains: A Comprehensive Guide
Growing autoflowering cannabis strains can be an exciting and rewarding endeavor for both novice and experienced cultivators. These strains are distinct because they can flower based on age instead of light cycle, which facilitates faster and easier growth. Everything you need to know to cultivate autoflowering cannabis strains will be covered in this tutorial, from choosing the best seeds to gathering buds.
Understanding Autoflowering Cannabis
Autoflowering strains are a result of crossbreeding Cannabis ruderalis with indica or sativa strains. Cannabis ruderalis is a hardy, low-THC subspecies of cannabis that evolved in the northern regions of Russia and Central Asia. It has adapted to harsh climates and short growing seasons, developing the ability to flower based on age rather than changes in light exposure.
Key Characteristics:
- Rapid Growth Cycle: Most autoflowering strains go from seed to harvest in 8-12 weeks.
- Compact Size: These plants are generally smaller, making them ideal for indoor grows and limited space.
- Resilience: They are typically more resistant to pests, mold, and adverse weather conditions.
Selecting Autoflowering Seeds
Choosing the right seeds is the first critical step. Here are some factors to consider:
1. Strain Type: Choose strains based on your desired effects (e.g., indica for relaxation, sativa for energy, hybrids for a balanced experience).
2. THC/CBD Content: Depending on your needs, select strains with appropriate THC and CBD levels.
3. Breeder Reputation: Purchase seeds from reputable breeders to ensure quality and genetic stability.
4. Climate Compatibility: While autoflowers are resilient, some strains are better suited for specific climates.
Setting Up Your Growing Environment
1. Indoor vs. Outdoor Growing:
- Indoor: Offers more control over environmental factors such as light, temperature, and humidity. Ideal for year-round growing.
- Outdoor: Cost-effective and utilizes natural sunlight, but is subject to weather conditions and pests.
2. Light Requirements:
- Autoflowers do not rely on a light cycle to flower, but they still need sufficient light to grow vigorously. Aim for 18-24 hours of light per day for optimal growth.
- LED grow lights are recommended for indoor growing due to their efficiency and adjustable spectrum.
3. Growing Medium:
- Soil: Use high-quality, well-draining soil with a balanced pH of 6.0-7.0. Amend with perlite, coco coir, or other aeration materials.
- Hydroponics: Offers faster growth and higher yields but requires more monitoring and maintenance.
4. Containers:
- Use pots with good drainage to prevent root rot. Fabric pots are highly recommended for their breathability and root development support.
Germination and Planting
1. Germination:
- Place seeds between moist paper towels and store them in a warm, dark place until they sprout (usually 1-3 days).
2. Planting:
- Once seeds have sprouted, plant them root-down in your growing medium. Plant them about 1-2 centimeters deep.
- Water gently and keep the soil moist but not waterlogged.
Seedling Stage (Weeks 1-2)
During the seedling stage, the plant focuses on developing a strong root system and its first true leaves.
1. Light:
- Provide 18-24 hours of light daily.
- To avoid heat stress and make sure you’re getting enough light exposure, keep the light source at the right distance.
2. Watering:
- Retain a constant moisture content in the soil, but do not overwater.
- Spray bottles work well for light irrigation.
3. Nutrients:
- Avoid feeding nutrients during the first week. Once the seedling establishes, you can start with a mild nutrient solution (¼ strength).
Vegetative Stage (Weeks 2-4)
In this stage, the plant undergoes rapid growth, developing its structure and foliage.
1. Light:
- Continue providing 18-24 hours of light daily.
2. Watering:
- Water when the top inch of soil feels dry. Ensure proper drainage to prevent root rot.
3. Nutrients:
- Gradually increase nutrient strength to ½. Focus on a balanced N-P-K (nitrogen-phosphorus-potassium) ratio.
- Consider using a vegetative nutrient formula high in nitrogen to support leaf and stem development.
Flowering Stage (Weeks 5-12)
Autoflowering strains will transition into the flowering stage based on age, typically around weeks 3-4.
1. Light:
- Maintain the same light schedule (18-24 hours). Autoflowers do not need a change in light cycle to flower.
2. Watering:
- Continue to water as needed. Avoid getting water on the buds to prevent mold.
3. Nutrients:
- Switch to a flowering nutrient formula with higher phosphorus and potassium levels to support bud development.
- Monitor for nutrient deficiencies and adjust feeding as necessary.
4. Pruning and Training:
- Pruning: Remove lower leaves and branches that receive little light to improve air circulation and focus energy on bud sites.
- Low Stress Training (LST): To increase light exposure and establish an equal canopy, gently bend and tie down branches.
Monitoring and Maintenance
1. Pests and Diseases:
- Examine plants frequently for indications of pests or illnesses.
- Make use of organic pest control techniques and keep the cultivation area clean.
2. pH Levels:
- Regularly check and adjust the pH of your water and nutrient solution to maintain a range of 6.0-7.0 for soil or 5.5-6.5 for hydroponics.
3. Air Circulation:
- Ensure good airflow with fans to strengthen stems, reduce humidity, and prevent mold and pests.
Harvesting
1. Timing:
- Harvest when the trichomes (tiny resin glands on buds) turn from clear to milky white, with some turning amber. This indicates peak potency.
2. Harvest Process:
- Cut down the plants and trim off large fan leaves.
- Hang the plants or branches upside down in a dark, well-ventilated area to dry for about 7-14 days.
3. Curing:
- Once dried, trim the buds and place them in airtight jars. Open the jars daily for the first week to release moisture and prevent mold.
- Cure the buds for at least 2-4 weeks to enhance flavor and potency.
Troubleshooting Common Issues
1. Overwatering/Underwatering:
- Symptoms of overwatering include drooping leaves and yellowing.
- Symptoms of underwatering include wilting and dry, brittle leaves.
- Adjust watering practices based on plant needs and soil moisture levels.
2. Nutrient Deficiencies:
- Yellowing leaves may indicate nitrogen deficiency.
- Purple stems or leaves can indicate phosphorus deficiency.
- Correct deficiencies by adjusting nutrient solutions and checking pH levels.
3. Light Stress:
- Symptoms include curled leaves and bleaching of bud sites.
- Adjust the distance between the light source and the plant to prevent heat and light stress.
Maximizing Yield and Quality
1. Training Techniques:
- Low Stress Training (LST): Bend and tie branches to create an even canopy.
- Screen of Green (ScrOG): Use a screen to train plants horizontally, maximizing light exposure.
2. Optimal Environment:
- Maintain stable temperature (70-85°F or 21-29°C) and humidity (40-60%) levels.
- Ensure adequate CO2 levels for enhanced growth and yield.
3. Genetic Selection:
- Choose high-yielding, potent strains from reputable breeders.
- Consider strains with specific traits, such as disease resistance or unique flavors.
