would this be a correct calculation to determine cfm ?

this wold be based on air exchange once per minute

32" high x 23" long x 18" deep = 5.27 sq ft

5.27 sq feet x 32 ( heigth ) = 168.64

168.4 x 60 exchanges per hour = 10117.4 cfm ?

i think you kinda went too deep .... cfm = cubic feet per min ..L x W xH =cubic feet for your area1.5ft X 2ft x3 ft its around 9 cubic feet .. id recommend changing the air maybe 5 time a min .. so the fan should be around 50 cfm or more

happy growin
