closet is 2.5' wide x 6.25' long x 6.75' high, so my CFM is 35 if i want to circulate air out every 3 minutes because my CF is ~105.
i read on a website to add 10-15% to your CFM for every uncooled light and 20% if your using a carbon filter, ill have one 600 watt HPS uncooled and a carbon filter attached to my exhaust fan.
15% of 35 is 5.25, so im at 40.25 CFM.
20% of 35 is 7, so im now at 47.25 CFM if i want to circulate air out every 3 minutes.
the smallest size exhaust i found is 60CFM which is what i would use. that seems small when comparing to other peoples exhaust fans, and when reading the sticky in this forum "calculating the size of an air conditioner" it says to add like 250CFM for every 600 watt HID to your already existing CFM...?
im lost, either a 60CFM is ideal from using that websites approach or a 35CFM + 250CFM(600w HID) is ideal from using that sticky's approach.
what size CFM exhaust fan do i really need for a 2.5 x 6.25 x 6.75 room with one 600 watt HPS uncooled and a carbon filter?
