Dsitance and amount of light is the biggest step for growing with CFL's and floro's. I know that there are huge debates out there about using CFL's & floro's for the whole grow. Most people do great when it comes to vegging but when it comes to flowering time, a lot of people are dissapointed. Flowering with cfl's & floro's is not much different than flowering with HPS. Only difference is, the HPS penetrates further from the light source which means you don't need much side lighting, if any. A lot of people grow from above the plants only and that is where the CFL & floro growers make mistakes. CFL & floro grows should penetrate the plant from all sides if possible and as close as possible (CFL's do burn but haven't seen a floro burn yet). I have seen CFL & floro grows turn out just as good as HPS grows, if not better and of course less lumens and watts. It all depends on distance and amount.

I have seen 467watts (34,XXX Lumens) of CFL's & floros combined to make the goodies and amounts you see in magazines, no lie, it can be done!!!
