I need some help, a lot of you guys say that you let the plant veg for a month and then cut the light to 12 and 12 for flowering. Can you tell me how you get a plant to grow large enough in a month? I use Miracle grow and it seems to work well. I also use potting soil. My plants have been three feet tall but all males so far. I only grow one plant at a time. But it takes several months. I do use flouresent lights. Thanks.
