    2 tents 1 fan…

    Hi everyone.. like the title says, I’m trying to see if I can run (1) fan to exhaust (2), small-ish tents. Tent 1 is 32x60x80 (almost 5x3) and the other is 24x48x60. Based on my beautiful sketch, does this seem like it would work? Here’s some details; 5x3 has a Viparspectra 480w LED...

    I am looking to start a small 4x4 tent up using Viparspectra XS series lights. Is 4 - XS2000 (rated at 240w each) going to be overkill?

    Scrubbing inside of a room..

    So if you scrub the air inside the room, what would the general rule of thumb be? Ex if I have a 6” fan pulling 400cfm out of the room with a CF.. what size filter/fan combo would be needed inside the room to prescrub as secondary measure? Would a 4 inch work?

    Should I over OVER size my exhaust fan?

    The space I plan on using is only about 112 cubic feet. A 6 inch 350-400 cfm fan should easily do the job for this size area and scrub with no problem but I’d like to prepare for the worst.. an 8 inch fan basically costs the same as a 6” (difference of $9 between Vortex S600 and S800).. would...

I may...
