Autoflower Seed Starting Tips
Autoflower varieties are extremely sensitive in their early stages of life and require constant attention. They are essentially hardwired to flower when stressed.
We suggest either planting seeds in the container you intend to flower them out in or root them in an easily transferable plug. We use 50 cell trays loaded with Earth Pots (available from www.obcnw.com).
These plugs (pictured above) allow for easy plant removal and minimal transplant shock. Seeds are planted ¼” and covered lightly with soil.
Like all seed, water in gently and ensure constant moisture. Do not over-water. Keep temperatures above 68°F, and between 75-85°F for fastest germination rates.
During all hours of darkness, and when temperatures allow, we light supplement our autoflower seedlings with high intensity lights. This isn't essential but it will give starts a strong beginning and can help keep conditions warm.
The MOST IMPORTANT STEP in growing autoflowering genetics is transplanting seedlings as soon as, or before roots reach the bottoms of plugs, usually within 7 days of soil emergence.
If autoflower seedlings become even slightly root bound, plants WILL flower regardless of how young they are. Four-inch tall colas are cute but unproductive, so be vigilant about checking plug bottoms for roots!
We prefer to plant them into the field at about 2-4” in height. If plants are deprived of light, they will grow tall and spindly, and may break during transplant or in the elements.
Autoflowers are also very sensitive to their environments, and planting in cold weather or extreme heat can cause plants to go into flower prematurely. Do your best to plan your planting schedule accordingly.
