i have a grow cab that is 2'x3'x4' high. 250 watt hps. 2x4" 80 cfm exhaust/intake inline fans. i thaught that the cooltube would bring my temps down but they are 100-110 degrees farenheit! im going to use co2 so i only need it to get down to around 90 degrees. do i need a more powerful inline fan? or use a window ac somehow. any help would be greatly appreciated
