Before and after grows, I wipe down everything and I mean everything in my grow room and tent with Orange oil. Floor, walls, lights, tools, containers, duct work, literally anything in that dedicated grow area. When I mix my soil for a grow, I always moisten with Orange oil and Garrett juice, 1 oz. ea per gallon of PH'd H2O. I have never had an insect, mold or mildew infiltrate my space.
