well if you dont have an ehaust port then just get carbon filter... sit it on the ground in your grow room and connect the inline fan to pull air through it. It will circulate the air inside the grow area and clean it without having to exaust it.

Today it has been eactly a month since they have sprouted, and they are starting to smell. I dont want to build a big grow box with an intake and an exhaust, are there any simpler options? Rating: 5
