      Tips: Effective treatment requires the exchange of air in your growing area in a period of several minutes. You can count the total cubic feet with multiplying length by width by height of your growing area. Then divide by the CFM(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 9' length x 9' width x 9' height, it contains a total of 729 cubic feet. With our 176CFM fan, you would treat your growing area within 5 minutes! Powerful and high-efficient for your grow room or grow tent!
