    skint at the mo so im thinking of using one of these

    Evercool DC Fan 120x120mm - Shiny Hardware LTD Evercool Case fans

    with this

    Evercool AD-01 Airduct 80x80x250mm - Shiny Hardware LTD Evercool Case fans
    with a homemade carbon filter in it.

    before i actually buy any of the stuff i just wanna know if the fan will be powerful enough to push the air through the filter, its rated at 84.26 CFM max (ive only set up a small grow room - 2.5 x 2.5 x 6 and im gonna be using an envirolite i got given- would use my HPS lamp but due to the heat factor its not worth it)

    when good exhaust there is no heat factor

    With the envirolite that looks like it may be enough... with HPS certainly not.

    That a good price for muffin fan. But u need better to do serious work. trust me. But for what yur doing cool! Why the extra peice tho, i gotta know. I have passive intake and it work asesome. I ahve a 400 in a 4 by 6 tent. with a 25 htg duct fan and a passive intake i can keep the tent the same as the outside air. Hope that helps as example. It all about exhaust! Are yu gonna fill that with charcoal? Thay would be cool!
