You do realize cmh technology puts led (uva/uvb), hps, and mh all in 1 bulb with a 20,000hr bulb life. If I didn't think cmh was the way to go, I wouldn't have swapped out my entire grow from hps/mh to all 315 cmh.
My 3 past grows should prove that it's the 600mh/hps killer.
It definitely is a technology I said I would look into as other people like them as well. I've ordered my 4 x 8 tent, should be here tomorrow. but anyway, I don't want to steal this tread, I have a thread going on this subject That I will be posting my CMH vs. COB questions.
