i use a 400 watt hps in my 2x2 closet. it works out just fine and my plant loves it! it can get hot in there if you don't ventilate properly(large inline fan).
jacked420 Reviewed by jacked420 on . Is my light TOO powerful?? So i have a small, 2' x 2' grow space. But i have the opritunity to get a 400 W HPS cheap (for flowering). obviously it would have to be hung about a foot above the plants....it has a cool tube. Will it be more trouble then its worth? should i just go for a 250. Does anybody have experience using a big light in small area? Rating: 5
