I got the same light...I had it in a 3x1x3 space and it torched the plants....I moved it to my walk-in closet and its vegging perfect since there is sooo much more space for the heat to circulate and get out...Unless you bought a cool tube youre gonna need to do some major venting...
ToPHeR31 Reviewed by ToPHeR31 on . Optimal # of plants for a 400w HPS/MH light I just purchased this light on ebay for 200. I was wondering if anyone can tell me how many plants i should try and grow for optimal production with this type of light. I want quality over quanity to maximize my yields. Would 6 plants be to much? Rating: 5
