  1. I'm in the process of setting up my grow closet. I will have a 150w hps and a 4-6 cfls the space is about 3x3x8 will I need air venting outside or air coming from outside or will fans on the plants work?
  2. there needs to be an adequate exchange of air. the room needs to be replaceds every 5 minutes.
  3. hmm in that case ill add a bathroom fan to the ceiling of the closet to vent out, any suggestions on how to bring clean air into the closet
  4. not a bathroom fan, you need an inline fan for sufficient air exchange. you also want to invest in a carbon scrubber to keep odor under control. once you have a decent extraction fan, that will pull fresh air into your space through cracks or an intake hole.
  5. thanks for the good info!
