extraction.

[wish.i.knew]

should both my intake and outtake fans (100mm-125mm rvk fans) be running 24/7? at the mo the out take fan is on 24/7 but intake only comes on with the light.
w.i.k
edit. i have a 1x1x2m bud box grow tent. and a 400w hps.

im not positive, but i wouldnt think so unless heat or humidity were a problem. i dont know how advanced you are or want to be, but ive read where the fans were hooked up to temp. and humidity meters.

like your avatar. I base on whether I use my fan after lights off exactly as twoguys said.....if the space is hot or humid, then I would leave it running 24/7.
