Bioworks Epishield O - Hobbyist Sizes Humic Acid 25 gal expanded) bag inBioWorks EpiShield O Miticide Works on Contact, Not Systemically EpiShield O is the bottle you reach for when mites show up and the crop is days from cutting. It runs on peppermint oil at 15% and clove oil at 10%, with the remaining 75% inert. Contact does the work here, paralyzing, smothering and drying out soft bodied pests rather than poisoning them. REI is zero hours and PHI is zero days, so nobody is locked out of the room waiting on an interval.
