Forgot to mention those cfls that i germed with, made my sprouts stretch like crazy. I moved to the 400 watt HPS after watching them stretch like crazy for 4 days, was upsetting and made me glad i didnt buy more cfls, as I see there not good for much of anything. Its in pic 4. Had 2 42 watts and 2 27 watts very close to them, closer than pic shows.
