So i purchased a carbon filter (a growbright 4in. Jr. Carbon Filter) and a 6in. inline duct fan with a rating of 160cfm free air flow (250cfm booster flow) inside a grow tent that is 39inx39inx79in. I've got the 6in fan mounted on the top of the tent, then attatched a 6in to 4in. duct reducer and applied flexible aluminium ducting (used commonly for clothes dryers)...i've read that in order to properly filter air you multiply the LxWxH and divide by 5 (air must be exchanged every 5minutes minimum) which means i'm roughly at 63cubic feet...divide that by 5 and you get 12.6cfm roughly...i've assumed that the 3 vents in the bottom of my tent would provide enough air in the bottom for the proper exchange, am i wrong? Also, in a day or two if necessary I will be putting some ducting on the outside attatched to a 4in flange on the bottom to allow more free air into the bottom of the tent...any idea on why i'm having troubles controlling the odor...i've linked below the products i'm using and would appreciate any and all input
