need help with carbon scrubber size for a 32" X 32" X 63"

wut size do i need 3in ? and do i need a biger tent? how much can i put in the tent

Get a 4" fan/ filter combo and a speed controller. You can get all 3 from virtualsunhydroponics.com (or another website) for about 175.

I say get the speed controller too because a 192cfm 4" fan sucks the walls in on my 4x2x5 tent lije a vaccum, I assume it will do the same to a 3x3.

if the tent only has a 3 and 6 holes can i use a 4 i got a 4 right now so if i can use it i wood like to know how

Just cable tie the duct sock on the tent tight around the 4" ducting then duct tape it. I do it and works fine. That is for using 4" ducting in a 6" opening. Im sure you could slit the 4" ducting and manipulate it to fit in a 3" sock if need be. Then cable tie and tape it also
