How to Grow Autoflowering Marijuana Indoors
What is an autoflowering plant?
An autoflowering or automatic plant is one that does not require a change in the light cycle to begin flowering. This variety will flower automatically when the time comes (usually 27 to 45 days from germination).
Its size is smaller than other varieties, and the time until harvest is also shorter, as is typical of autoflowering strains.
It also requires more hours of light. While other varieties use 18/6 for growth and 12/12 for flowering, autoflowers should remain under 18/6 throughout the entire grow, which is recommended to maximize yield.
Germination Stage – How to Grow Autoflowering Marijuana Indoors
1 – Air:
Good air circulation is essential to keep oxygen levels high and to constantly refresh the environment. This is necessary to prevent seeds from drowning and to ensure successful sprouting.
2 – Temperature:
This is a crucial factor for proper germination. The ideal temperature range is between 24°C and 26°C.
3 – Relative Humidity:
Humidity should be as high as possible, but without pooling water where the seeds are kept. A few droplets are fine, but excessive condensation can negatively affect the seeds. Ideal humidity is between 85% and 100%.
Once you’re sure you can maintain these conditions, you can proceed with germination.
Traditional germination method:
Most growers are familiar with the technique of placing seeds between moist paper towels, storing them in a closed container, away from sunlight or high-intensity grow lights.
Once the seed sprouts, it should be placed under a light source (being careful not to overheat it to avoid stretching).
Finally, once the plant reaches a suitable height, it should be transplanted into a larger pot.
Direct germination method (alternative):
A more direct method is becoming popular. It involves placing the seeds directly into pre-moistened soil, making a 3–5 mm deep hole, inserting the seed, and covering it lightly with more soil.
Lastly, gently water the area where the seed was placed. While this method reduces transplant stress, experts agree that the paper towel method remains more reliable.
