Noob question: The hell is LST?yea some dub and some triple in size durring flowering. I just copped a hortilux w. enhanced spectrum with more blue light and just enough red to promote flowering. Guy told me it will bud nicely and witht the exta blue spec will make denser less stretched nugs so a new light could help you too. Topping them or LST can help you out in reducing size of a plant also
