Do you guys really think she needs a 6 inch fan?.....it is just that my 40" x 40" x 79" tent has a 4 " inch ventech inline fan from cramazon and the matching speed controller and i only have the controller set a 1/4 of the way to full and it keeps the tent at 80.....with it off....it approaches 91 to 92.........i am sorry, but i think 6 inch might be overkill imho
