I got the same cabinet as you do but I got the 3ft one. My only question is whats that white shit on the walls that you're using? The only down side to the cabinet is that it isn't light proof, mines glows in the dark at night. I'm thinking about painting the insides white and using weather...
I think its great that your doing an led grow setup. Your research will help in trial and error any way you put it. I think the leds are great for veggin and the reds are good for flowering but adding a few cfls wont hurt either. Any how I'm going follow up on this grow from start to finish, BTW...
if your on a budget go with the cfls 42w, buy at least 4 and some y adapters, dont fuck with the reflectors on your clamp lamp cause you wont be able to use the y adapters.
