Fan/Filter requirement for 60''x48"x24" growtent W/ 250w CFL

hello guys!

i'm starting to purchase all the supplies for my grow but i'm somewhat stumped when it comes to the fan and filter.
my tent is 60''x48"x24" and the two options are (4" fan and filter @190CFM) and (6" fan and filter @440CFM)
i'm thinking that the 4" fan will suffice but i've never setup a tent before.

any input is greatly appreciated.
thanks in advance.

What are you using the fan for? Cooling your hood? Or for a Fresh Air Intake/Co2?

Go with the 6 inch for sure...more fresh air the better in my opinion...good growing

its 250W CFL, no air cooled hood. the fan and filter are the whole of the exhaust and odor management system thats going into this tent

i think i might go with the 6" inch fan/filter combo.
more airflow and bigger filter = better odor control which is a big issue for me.

The minimum CFM for your area is 13 CFM
