These high-yielding autoflowering cannabis strains are easy to grow and don't require as much care as photoperiod strains.
What Can Be Considered a High-Yielding Autoflowering Strain?
Autoflowering cannabis strains, due to their unique characteristics and rapid growth cycles, typically yield differently than their photoperiod counterparts. While traditional photoperiod strains can offer larger yields due to their longer vegetative growth phase, which can be extended by the grower, autoflowering strains transition to the flowering stage based on age, limiting their vegetative growth time. However, advances in breeding have led to autoflowering strains that can still produce impressive yields in a shorter timeframe.
The yields from autoflowers can vary widely depending on the strain, growing conditions, and care given to the plants. On average, autoflowering strains can yield anywhere from 30 to 150 grams per plant when grown outdoors. Indoor growers might see yields ranging from 400 to 600 grams per square meter of grow space, especially under optimal conditions and using sea of green (SOG) or screen of green (SCROG) setups that maximize light exposure and plant density.
Some of the most advanced autoflowering genetics can push these averages even higher under ideal conditions, with certain strains capable of producing up to 200 grams per plant outdoors and over 600 grams per square meter indoors. But keep in mind that these figures are highly dependent on factors such as the quality of the growing environment (light, nutrients, humidity, etc.), the grower's experience, and the specific genetics of the strain being grown.

How to Increase the Yields of Autoflowering Strains
To maximize the yields of autoflowering cannabis plants, it's crucial to optimize the growing conditions and employ specific cultivation techniques tailored to the plants’ unique growth patterns. Here are some key tips for increasing autoflower yields:
- Start in the final container: Autoflowers don't like to be transplanted. Start your seeds in their final pots to avoid transplant shock, which can stunt growth and reduce yields.
- Optimize lighting: Autoflowers thrive under light. Use LED or full-spectrum lights, and consider a light schedule of 18-24 hours of light per day to encourage photosynthesis and growth.
- Manage nutrients: Begin with a light nutrient regimen to avoid overfeeding, especially during the seedling phase. Gradually increase the nutrients after that, focusing on higher phosphorus and potassium levels during flowering to boost bud production.
- Maintain ideal conditions: Keep the growing environment within optimal temperature and humidity levels. Autoflowers prefer temperatures between 20-25°C (68-77°F) and relative humidity around 40-50% during flowering.
- Use LST: Employ low-stress training (LST) techniques like bending and tying down branches to expose more of the plants to light without causing stress that can hinder their growth.
- Choose high-yielding strains: Start with genetics known for higher yields. Research and select autoflowering strains that are bred for both vigor and productivity.
