completed filter
i have the fan pushing rather than pulling through it but either way works fine.

i have used a fiter a little smaller than this in a cabinet with 4 plants in it with great success



took around a half an hour
c of green Reviewed by c of green on . ? i have seen some how to carbon filter threads but the average cost after the fan is $150+.i am getting ready to build another 10$ carbon filter and was wondering if you would like a how to?it is good for a small cab grow or a drying room.i currently have one in my veg with 18 plants...cant smell a thing unless i put my nose to the plant(then it is quite potent) Rating: 5
