hey guys. i'm finally about done with my flowering box. the box is in a 12x10 room in my basement. their is a mother box in there also. the box is 6.5x3.5x6 with 2 600 hps's in it. the lights are mounted on both sides of a 6" vortek fan all ducted from one side of the box to the other. i have 1 freestanding carbon filter in the room itself, and i plan on adding 1 on the light exhaust. my question is, whats a good fan/filter designed for heat and odor that you can vent to the outside (ducting on both sides)? i also have the option to vent behind my wall because i framed out the basement 12" of the block to compensate for my french drain. do you think i could exhaust there or would it create mold issues. thanks in advance
