Getting mites is one of my fears. I heard from a local hobbyist that diatomaceous earth will also keep mites away. I decided to give it a try, so my cultures are currently sitting in about a quarter inch of diatomaceous earth in a couple of seedling trays. I’m new to the hobby, though, so I don’t have much experience. I’m interested to see what more experienced individuals have to say about the effectiveness of traditional mite paper vs. alternatives like diatomaceous earth.
