Hello all, I just bought a 315 watt cmh for a 4x4 grow space and was wondering how many members have used this light from the seedling stage on thru veg. If so what is a safe distance to hang the light above seedlings. Thanks all.

They veg very nice. Just put er at the ceiling to start. 4x4 with a 315 was a good choice imo. They seem to cover more than 3x3 imo but it depends on the reflector I guess
i agree. They don’t replace a 600w mh/hps but are wicked little units. Just like how folks say 400 watts of led watts replace a 1k.. it’s like dude those lights are efficient and wicked cool.. ain’t gotta lie ta kick it lolI think they are good for 4x4 veg and 3x3 flower in the tent but in my open room only one 315 struggled to light a 3x3 area.
That is the sun system verticle open remote reflector and a galaxy lec ballast.
Multiple 315’s would work better I think they need some overlap to deserve the overblown hype about them.
They are a little better than a 400 metal halide or hps is the truth.
Exactly, Dirtbag. T5 or even CFL grow bulbs. That's all you need for seedlings. I have my 315 cmh 12-14 inches from my Scrog and it rocks...but you might not want to waste the limited lifespan of the bulbs on seedlings that don't appreciate it.
