Carbon Filter size??

Hey i was wondering how big of a carbon filter i would need for a grow of about 8 plants. Thanks.

....depends on the size of your room. LxWxH

...the carbon filter and the fan will have a reading in CFM's or Cubic Feet per/ Minute. Find out what the square feet of your grow area is first off. You need to be able to refil your room 5 times per minute.

...so, if you had say 100 sqft space, you'll need a filter and fan that moves 500 cfm's.

a flower area of 67 inch long 84 inch tall and 30 inch deep

so....your basically working with a little over 100 sqft. You'll need to exaust the whole area out 5 times per minute, so....you'll need about 500 cfm's....have a look at this filter, follow this link >>>> http://www.progressive-growth.com/proddetail.php?prod=29007

...now you'll need a fan with equal cfm's, like this >>> http://www.maxgrower.com/vortex-6-inch-powerfan-4496449.html

yeah, I've got a 435cfm for my room.... 10x15.. it's not enough.... this is not a case where less is more... I'll be upgrading to a 1200cfm eventually...
