How to Grow Big Autoflower Plants: A Comprehensive Guide


Autoflowering cannabis plants have gained immense popularity among growers for their rapid growth and ease of cultivation. With the right techniques and care, you can cultivate auto flower plants that yield large, potent buds. In this comprehensive guide, we will delve into everything you need to know about growing big autoflower plants, from selecting the right strains to optimizing environmental conditions and maximizing yields.

Understanding Autoflowering Cannabis

Before diving into the specifics of growing big autoflower plants, it’s essential to understand what sets them apart from photoperiod varieties. Unlike photoperiod plants, which rely on changes in light cycle to trigger flowering, autoflowers transition from vegetative growth to flowering based on age. This characteristic makes them ideal for growers looking to streamline their cultivation process and achieve quicker harvests.

Advantages of Growing Autoflower Plants

  1. Shorter Life Cycle: Autoflower plants have a fixed life cycle, typically ranging from 8 to 12 weeks from seed to harvest. This shorter duration allows for multiple harvests in a single growing season.
  2. Compact Size: Autoflowers tend to stay small and compact, making them suitable for indoor cultivation or discreet outdoor growth.
  3. Resilience: Autoflowering strains are known for their resilience to environmental stressors, making them more forgiving for novice growers.
  4. Continuous Harvest: By staggering planting times, growers can maintain a continuous harvest cycle, ensuring a steady supply of fresh buds.

Selecting the Right Autoflower Strains

The first step in growing big autoflower plants is choosing the right strains suited to your preferences and growing environment. With a wide variety of autoflowering genetics available on the market, it’s essential to consider factors such as yield potential, cannabinoid profile, and growth characteristics.

Factors to Consider When Choosing Autoflower Strains:

  1. Yield Potential: Look for autoflower strains known for their high yields and dense buds. Strains like Critical Auto, Girl Scout Cookies Auto, and those available from reputable seedbanks like Herbies Seeds are renowned for their impressive harvests.
  2. Cannabinoid Profile: Consider the cannabinoid profile of the strains, including THC and CBD levels, to ensure they align with your desired effects.
  3. Growth Characteristics: Pay attention to the plant’s growth habits, including height, branching structure, and overall vigor, to determine if it’s suitable for your growing space.

Optimal Growing Environment for Big Autoflower Plants

Creating the ideal growing environment is crucial for maximizing the size and potency of your autoflower plants. From lighting and nutrients to temperature and humidity levels, every aspect plays a significant role in determining plant health and yield potential.

  • Lighting Requirements. Autoflowering cannabis plants thrive under a consistent light cycle, but the intensity and spectrum of light are equally important for robust growth and flowering. While natural sunlight is ideal for outdoor growth, indoor growers can achieve excellent results with full-spectrum LED or high-intensity discharge (HID) lights. Aim for a minimum of 18 hours of light during the vegetative stage, followed by 12 hours of uninterrupted darkness to induce flowering. Supplemental lighting during the flowering stage can further enhance bud development and yield.
  • Nutrient Management. Providing your auto flower plants with the right balance of nutrients is essential for promoting healthy growth and maximizing yields. Start with a quality potting mix or coco coir medium enriched with beneficial microbes and organic amendments. During the vegetative stage, focus on nitrogen-rich fertilizers to support vigorous growth and development of foliage. As the plants transition into the flowering stage, they switch to bloom-specific nutrients high in phosphorus and potassium to promote flower formation and bud development.
  • Temperature and Humidity Control. Maintaining optimal temperature and humidity levels is critical for preventing stress and ensuring optimal growth throughout the plant’s life cycle. Autoflower plants thrive in temperatures ranging from 70 to 85 degrees Fahrenheit during the day and slightly cooler temperatures of 60 to 75 degrees Fahrenheit at night. Keep humidity levels between 40% and 60% to prevent mold and mildew while promoting efficient nutrient uptake and transpiration.
  • Air Circulation and Ventilation. Proper air circulation is vital for preventing heat buildup, regulating humidity, and strengthening plant stems. Install oscillating fans or circulating fans in your grow space to promote air movement and prevent stagnant pockets of air. Additionally, ensure adequate ventilation to remove excess heat and humidity, especially in enclosed grow spaces. A combination of intake and exhaust fans, along with passive vents, can help maintain optimal environmental conditions throughout the grow room.

Techniques for Maximizing Autoflower Yields

  1. While autoflowering cannabis plants are inherently productive, employing specific cultivation techniques can further enhance yields and quality. From training methods to pruning techniques, here are some strategies for maximizing the potential of your autoflower garden.
  2. Low-Stress Training (LST). Low-stress training is a gentle yet effective technique for manipulating the shape and structure of autoflower plants without causing undue stress. By gently bending and securing branches during the vegetative stage, growers can encourage lateral growth and create a more even canopy. This allows for better light penetration and airflow, resulting in increased bud sites and higher yields.
  3. High-Stress Training (HST). For experienced growers looking to push the limits of their autoflower plants, high-stress training techniques such as topping, FIMing (short for “f*ck, I missed”), and supercropping can be employed to stimulate vigorous growth and maximize bud production. These techniques involve strategically damaging or removing portions of the plant to redirect energy and promote the development of multiple colas. While HST methods can increase yields, they also carry a higher risk of stress-induced hermaphroditism or stunted growth, so caution and careful observation are necessary when implementing these techniques.
  4. Defoliation. Removing unnecessary foliage during the flowering stage can improve light penetration and airflow within the canopy, resulting in larger, denser buds. Focus on pruning away fan leaves that obstruct light to lower bud sites while leaving enough foliage to support the plant’s metabolic processes. However, avoid excessive defoliation, especially during the early flowering stage, as it can stress the plant and hinder bud development.
  5. Lollipopping. Lollipopping involves removing lower branches and foliage that receive minimal light exposure, allowing the plant to redirect energy towards upper bud sites. This technique helps concentrate the plant’s resources on producing larger, more potent buds while reducing the risk of mold and pest infestations in the lower canopy. Lollipopping is typically performed during the transition to the flowering stage and can be repeated as needed to maintain an open, airy canopy.

Final words

Growing big autoflower plants is an achievable goal for both novice and experienced growers alike, thanks to their rapid growth and forgiving nature. By selecting the right strains, optimizing growing conditions, and employing cultivation techniques tailored to maximize yields, you can harvest bountiful crops of high-quality autoflower buds. Remember to pay close attention to the needs of your plants throughout their life cycle, from seed to harvest, and enjoy the rewarding experience of cultivating your own cannabis at home.

Whether you’re a hobbyist grower or a commercial cultivator, the satisfaction of nurturing a thriving garden and harvesting big autoflower buds is incomparable. With dedication, patience, and a bit of knowledge, you can unlock the full potential of autoflowering cannabis and enjoy a plentiful supply of premium-quality buds for your enjoyment.
