How many cfm exhaust?

im using a 3.3' x 3.3' x 6'7" tent. I've been told exhaust is very important and it's time to get it bought. Is there a rule of thumb for the cfm ratings I need? I was told I need to match the cfm on the carbon filter and fan. Can anyone help me figure out the cfm I'll need for this Tent? I think I have a few 6" ports on the tent. Everything will hang up top hopefully. Also if anyone can point me in the direction of where I can get the best bang for my buck? Thanks

yes that's 72.9 cf ..you want to change air a few times a minute so a 200cfm should do....buy a 6 inch ventech like so or any brand you like it's 240cfm...should do fine. 25$

How about carbon filter to match? Any recommendations for those? I'm seeing a bunch of different ones.

do you need one?

Yea. Tent is in my bedroom. Should have probably clarified.

you live with ppl you don't want to know?

No. I'm in California, got my medical card all that in my own home. Just had no other place but in my room. I'll be sleeping a few feet from it. Don't need all that smell in there if I don't have to.

ok then buy a scrubber that will fit....imo if I were legal and only growing in a 3 foot tent, I would just vent out side and call it a day...
