Autos grow

if you going to keep them in containers bigger is better, if you going to transplant into soil line the bed with grass clippings to act as a much and prevent splash back from the soil on the bottom of the plant. They will drink a lot and the pot can become very small very fast. might need to water multiple times a day. and if its black plastic it can become over heated and cause issues. also if they are photoperiods you have to be wary of light sources at night like motion detection lights causing issues in the dark period. this should not be interrupted. autoflowers less of an issue. Good Luck!
