I lost most of my sense of smell as a result of a motorcycle accident many years ago. Sometimes I can vaguely smell something. Right now, my flowering gelato smells wonderful, but I have to stick my head in the tent to smell it. My wife has her sense of smell, so I depend on her to tell me what she smells. Both of us like the aroma of flowering cannabis, and we don't worry about the neighbors. She only complains about the scent of some of the amendments I use. So, for that, we have charcoal filters on the exhausts. They're disconnected most of the time. I only connect them when she complains. They last longer that way.
