I just purchased a deep water culture kit from stealth hydroponics. Not real sure how well it's going to work but I wanted something easy for my first grow. My question is about lighting. I really only have about 200 to 300 dollars to spend on lighting. I've heard about the different kinds of setups but I think I may go with cfl's. Can anyone explain to me the lighting cycles and how many lights I will need for a 4 plant setup?
