These are photoperiod plants. I do grow autos but haven't done enough research to apply the technique to them. I use Megacrop V2 one part for the autos in 3 gal cloth, or 5 gal SIP buckets. My environment in the basement this winter was all over the place and the autos suffered. Mostly small plants with little yield. Now that spring is showing my humidity and temp can be controlled more easily and shouldn't have a problem keeping it within perimeters. Hoping to be able to move from the basement in the future to an enclosed room (lung) and will control the lung room environment instead of individual tents.
