Great Idea! I was curious what this would do to CFM's as well. Is the reduction similar to a Can Fan Filter (about 150 or so is the rated reduction I read somewhere?)

I have a room that i was going to use a 6" Hight output fan to pull through a Can Filter 75, or maybe a 66......wonder if the fan and this set up will match or if the fan will be too strong now.

Interesting feedback from BongJuice and somebody else who reported severe reduction issues.

Anybody else have any feedback on a "room" sized grow?
