This is what I will be using, in a closet space of 3 x 2 x 10 obviously going to have fans blowing in and one out to keep temps down.

Thanks for the reply Dutch
THContent Reviewed by THContent on . Should I use MH at veg and HPS during flowering? Hey just a basic question to the pro's, should I use MH during vegetative growth period, and switch to HPS when flowering period starts? Or should I just use the HPS throughout the entire growth cycles, since there is max output with that? I was also looking in to a LED setup but not quite sure if it covers all aspects of needed lighting. Any and all help is appreciated! Rating: 5
