I'm starting a small grow in an outdoor closet. I plan on growing one or two plants and then drying them in the same room (not at the same time) because it is the only place I have. The walls are painted white, but I was wondering if putting down a reflective material could also help keep the smell in the room. I'm also using a small air purifier in the room.
What should I use to keep the smell in, if anything?
