Just getting my parts in the mail to set up my closet....its 2x4x7ft. I will be running 2 x 250hps with cooltubes. I just got my fan in the mail thats rated at 400cfm. For my venting i was planning on setting it like filter>Fan>duct>cooltube>duct>cooltube>duct>exhaust.


My room is 56 cubic ft. assuming( but you know what they say about assuming) that my fan loses 50% efficeincy through the filiter duct and ct lets say it moves 200 cfm. That means my fan will exchange the air in the closet 4x per min. Overkill? Not enough?

thanks
