it can cause them to sex out early, but they shouldnt bud, inside u give them 18 hrs light, u got a good 3 or 4 hr decrease being moved out, and the plant thinks falls coming, but then the rising days of summer will tell it its not fall, and to continue vegging, ive had a bunch of plants sex out so far, which is great for me, get the males out early its less work and watering and what not
