Im beginning to grow soon and have a DWC system(from stealth hydro), a grow tent, but no lights. i know that i should get the best lights possible, but im ballin on a budget. i figure that cfls will suffice for the mean time. i'll have to get at least two different kinds: one for veg and another for flower right? How many would i need for both phases of growth? i was thinking two each but i dont know. Let me know if you can help. thank
