hey LokaGass, if the smell is strong now , imagine when it's in flower, you should always have air flow anyway. Without a fan and without a filter , your options are limited. There are sprays that take out the smell , and gels you can use on the exhaust, but really you should have a small fan and a small filter next to it, just stand the filter on the ground and use the fan on top, that should work for you. Hope this helps ! 🚀
