Has anyone experimented with homemade/DIY recipes for hop gaurd? I beleive it is a patented extract, obviously made from hops. I have a strong tincture I made out of vodka and hops, and wondering if that could be used to knock back the mites a little bit? I was thinking of lightly soaking a cotton ball or a piece of clothe, and placing it in between 2 frames. Any problems that anyone can forsee?
