    my room is 18 feet by 14 feet and 7 feet tall.... I am going to run 8 1000 watt lights... what size extractor and inline do i use.... More acuretally what size cfm for both? I did the math and if im correct this is what i got. 1600 cfm for extractor and 900 for intake?

    i believe you take your area and thats what cfm you need. double if you add a carbon filter.

    Hi hemphero,
    I come up with 1764 cubic feet. My best guess would be 2 fans, one at either end of the room. Like I said a guess.
    Cheers,
    bruce
