Too Much Air Flow?

    Hey there guys and gals,

    Quick question as part of my pre-planning. Im thinking of using a 1.2m x 1.2m x 2.0m grow tent. Would a centrifugal fan pulling out 220 m3/h be overly excessive? Basically would it potentially cause me any problems?

    Cheers,
    Dutchey

    That's like 120CFMs, right?

    Not excessive at all. I would say at least 200CFMs

    So just to put in more accepted format the proposed room is 3' 11" x 3' 11" x 6' 6.7"
    So it would be 374 CFM

    I'm saying the fan is only about 120 cfms. You want a fan rated for 200+ cfm.

    I have a 400w hps in a 2ft x 3ft x 5 1/4ft tent with a 190CFM fan, temps stay in the 70s to low 80s

    Sorry I think I'm miss understanding? CFM being Cubic Feet per Min?

    Yes. 220 m3/h =about 120cfms

    A 400 m3/h fan will be much better
