any help please. . .

Just about everything I\'ve seen about shade pole fans or squirrel cage--exhaust fans anyways--the people are using 180, usually 265 cfm or more. If the supposedly widely accepted formula is cu ft (l x w x h) / 5 and your high and think of the equation backwards. . .

265 x 5 = 1325 cu ft. . . isn\'t that the size room a 265 cfm cage fan room would support cleaning the air every five minutes???

or that it would theoretically clean out a 13 cu ft fridgegrow 20 times per minute???

I know you want more often than every five minutes, but don\'t you have to give the CO2 a little chance to mingle???
