can anybody tell me what i need to make a carbon filter, can i use the filter sheets that are used for cooker hoods. if i could find a way to stop the smell from 4 plants. i would have my oulet going into the attic , instead of going out the gable end, that would mean drilling a 6 inch hole, which i dont fancy doing due to nosey neighbers i want to get rid of all the smell........is this possible ?
i've heard of air ionizers, they're supposed to work or you cover the odor with something else, i bought something like an air freshener at my local grow shop
air ionizers that sounds interesting but i cant see how they get rid of the smell ? where would the smell go i will look into it thanks for the idea smoochy
