So I'm getting my exhaust inline fan in the mail today and I just wanted to make sure I wasn't going to harm anything. I have a grow tent that is 2x2x3 (feet) and based on a bathroom CFM calculator I found online it said I need a cfm of at least 2. So the fan I ordered has a CFM rating of 100. Will that hurt anything with my grow? I figure the more fresh air the better, right? I also have an oscillating tower fan permanently inside the tent.
