I have my regular carbon filter PLUS I'm running tubing out with ona gel in a cup inside of the tubing with a fan on the end pulling the old smelly air threw the tubing over the ona out the speaker hole over another ona/cinnamon mix cup hidden behind the setup o and my grow box is a gutted out old bigscreen tv I've been working on this little at a time would post pics but I'm new here and still figuring that out
Im just going to say that if you seal your pipe up good you wont get any odour from your filter. Unless your filter is old and no good anymore. But if its new you dont need to worry. I took duct tape and made mine tight. No odour at all. Sent from my SGH-I747M using Grasscity Forum mobile app
its sealed off and works great.. the ona was just a stoned idea Im trying lol but its actually working I walked in and all I could was linen and cinnamon
them damn stoned ideas are way too time consuming you should be good with the carbon filter like ^he said
