D'oh! I meant 400w HPS. Hahah I smoke too much herb. I don't even think 400w (non equivelant) CFLs exist.

I might be considering the 600wHPS though. How big of a growing space does a 600w cover? 6X6 or something?
Buddahbear Reviewed by Buddahbear on . Amount of CFL vs Higher Wattage. Is it worth it to drop the extra money on the big CFLS (105-125 watt 30-50$ a light) Or use multiple low wattage? What do you guys with experience think, because I'm considering using all CFLs to save money but still would like to attempt a sea of green grow in a 4X4 organic soil bed (for 16 clone SOG). Rating: 5
