Setting up my indoor grow with some Northern Lights clones. Usind a 120w led to avoid heat issues. I ordered a 20"x36" footprint grow tent. I know the LEDs may need a cfl boost for flower and am ready for that. The problem I have is the closet is in the middle of my house with no way to vent outside. With 2-3 plants max could I just run a carbon scrubber 4" or 6" inside the closet recirculating the scrubbed air? Got cleaning people and pest control coming thru once in a while and gotta keep it stealthy.
if you only use an led light... and you introduce Co2 maybe... but i would still advice you to replace the door and vent the grow out of the closet
