I definitely agree with the post about CFL's and the fact that they should be close but I think you can grow at least the first few weeks with the purple grow lights. I have a plant that is just breaking the surface with only two purple grow lights. They say they are grow lights so I assume those are the correct ones, not the ones to ditch? Anyway in your case put the purple lights basically right on the plants because from my experience they do not get hot barely at all. Good Luck, hit us with some pictures soon:rasta:
