I lost my sense of smell years ago, so I must rely on other people to tell me if there's an odor from the plants. No one has ever mentioned the plants themselves. The soil, however, is a different issue. My wife recently complained after I added mycorrhizae. She has also complained about the smell from top dressing dry nutrients. We therefore now have refillable charcoal filters on both tents and I'm $200 poorer. I also ran the dehumidifier and let the top layer of the soil dry. I didn't know humidity could affect charcoal filters, but it makes intuitive sense. I already knew that adjusting the humidity could improve odors.
