That sounds like an interesting solution. If you ever do that I would like to see a pic of it. Actually the fan that I use is really pretty quiet. Quieter than the 4" bathroom fan that I used to use. Got it from amazon.Amazon productThats probably what I would have to do. Noise is an issue so I was thinking of taking off piping, doing the cheap carbon filter with the pencil cups and making 6 of them each pulling air from a different part of the top if the tent. Kinda like this: -_-_-_
