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.
The most important step in growing autoflowering varietals 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 2-3” in height. If plants are deprived of light, they will grow tall and spindly, and may break during transplant or in the elements.
Water in your field for at least 24 hours before transplanting. We strongly recommend using Vitamin B1 (Super Thrive, Thrive Alive, etc.) and liquid mycorrhizae (Myco Apply Injector Endo, Great White Liquid Orca) mixed into water wheel planter or other plant apparatus reservoirs. This will limit shock.
