  1. Can someone answer me this . Is it better to have 2 exhaust fans or 1 with the equivalent cfm3? I’m considering buying either 2 at 1400cfm each or 1 at 2800cfm , I wanted just the one but realised it would be much heavier to install but then I started wondering if I had 2 they Would possibly fight against each other?

  2. I tried doing this before, than my girlfriend made it drop below 60 at night because it was getting "too hot". She still cant grasp the fact you cant do that to plants.

  3. I don't use a carbon filter so keeping the pressure negative in my grow room is essential to keeping the smell from entering the rest of the house. Note I can smell my grow two houses down but here in Canada its legal and its all good!
