You can count the total cubic feet with multiplying length by width by height of your growing area. Then divide by the CFM Parameter(cubic feet per minute) of the fan, you will get the time that the fan exchange the air for your grow area. For example, if the size of your grow tent is 8' length x 8' width x 8' height, it contains a total of 512 cubic feet. With our 120CFM fan, you would treat your growing area within 5 minutes! Convenient and high-efficient for your grow room or grow tent!
