tent vent help

I have a 3x3x6 grow tent with 2ft 8 bulb t5. I plan on addin a carbon filter and exhaust fan. Can anyone give me advice on a fan and filter. Tent has 4" vent ducts. LxWxH=54 so am I lookin at a fan to exhaust 54cfm a min? And how much cfm must I add to push the air thru the filter? Reps for help! Thanks

A 4in vortex with a matched filter should do the job nicely. I think it's about 200CFM or so. You need a high exchange rate, like 3-4 times per minute to keep it cool.

Thanks fred!

Make sure your filters cfm is rated higher than your fan cfm. Id go for a 100mm rhino {350cfm} to go along with the vortex.
thats what i use along with my 4in hvk (175cfm}, your space is a little bigger than mine though.
Rhinos all the way.

Looked em up monty python but I can only find em thru the uk. Any us companies carry rhino?
