quick quesition for my closet set up

[tommyboi_420]

hello all in IC land,i wanted to know if im doing the math right on the cubic feet in my closet? WIDTH X LENGTH X HEIGHT = CUBIC FEET so my closet is 3ft W x 6ft L x 8ft H i get a total of 144CF, ok then im taking 5 divided into the 144 with an anser of 28 with a remainder of 4..so is this saying i need a inline fan with a rate of just 28.4 CFM to cycle my closet with fresh exchanged air every 5 minutes???,seem to low of a number to me, i have 2 400W CMH going in there with just plain jane hoods(non-cooled).as for intake i was thinking about "5x13" opening through the closet door,maybe 2 of them..the door is your standard simi hollow 6 pannel..as far as a carbon scrubber im thinking of one of the DIY one's in the diy thread....shoot me some idea's/thoughts on what size inline fans CFM will work the best on air extange and heat control,and if my passive intake size is big enough...be safe everyone

I'd get a fan that can replenish the air inside the grow 3-5x per minute rather then replenish all the air in the grow in 5 minutes.

So instead of a fan that is rated 28.4cfm I'd recommend a fan that is rated atleast 392-440cfm (6" inline centrifugal).Especially if adding a carbon filter.

Yep. Once every 5 minutes is going to be too low. Jnugg knows what's up with the ventilation
