Autoflower varieties are extremely sensitive in their early stages of life and require constant attention. We root our seed in EarthPot (available from www.obcnw.com) degradable plugs in 50 cell trays. These plugs 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. We use a minimum of 10k watts in a 30x100ft greenhouse. 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 when roots reach the bottoms of plugs, usually within 7 days of soil emergence.

If roots become bound inside plugs, 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.

Field planting conditions are also important with autos. It's best not to plant during cold spells (temps below 50-60 degrees) or in heat spells (temps 90+), particularly if using black plastic mulch, as it increases soil temperatures drastically.
