Where is the carbon filter? Is that it over the end of the duct? I dont think that will really stop much smell.Made home made one. Lost about 70% air flow in exuast. Exuast feels kinda warm after 20 mins but not hot... Think it will be ok?
How big is your grow space? If its really small, it might help a little. Is that your only odor control? If you grow a stinky variety, i'm sure it will over power it.It's inside the duct
Used close to 7 oz of carbon
