Fans

  1. I have 1000w and am just about done building the room for it. However I had a venting question. The 1000w has a cool tube(glass and 2 holes for ducts, right?) so I'm imagining I have to get 2 for that? But then I need to pump co2 in to the room, would I also need to pump the air out at a separate location as well?


    I need to know what kind of fans(can't afford few hundred dollar vortex's) and how many I need I suppose. One of the few things I haven't researched too well.

    Do you guys use fans that attach in to the middle of the 6" ducting as well?
     
  2. Theres a sticky for ventilation (under grow room design) it'll answer all your questions!
