Zandor, I took your advice and ran with it. I got all the materials needed and got to work. In pic 1 you can see that i placed the filter with the metal screen side down. Pic 2 is how i layered the activated carbon. Pic 3 is how i put the second filter over the first one with the metal screen side up. I made two of these and ducted taped those together to form one big filter. I found a box big enough to be the housing. I cut the square hole toward the bottom of the box where the most carbon will be in the filter so the air that flows through, flows through the carbon. On the other side i cut a six inch circle where the fart fan was inserted. I have the fart fan on a timer and speed control. Do you think that this will take care of the odor for a 6' x 9' room? Again thanks for the help Zandor.
Happy Growin!!!!!!!!!1
