*Treating soil with heat is an effective option to consider in many situations to propagate healthy, strong plants year-round by controlling common soil-borne weeds, harmful pests (i.e. snails, gnats and eggs), molds (damping off), and disease safely, economically, and chemical-free in your growing media…pasteurize BEFORE you plant your valuable seeds, cuttings, and transplants. Successful growers around the world have been using Pro-Grow’s heavy-duty equipment to carefully control their growing mixes in-house. Sterilize screened media first and then add beneficial amendments and supplements. Using unsterilized media in the beginning may introduce a variety of problems into your growing operations. Minimize your exposure to toxic chemicals with soil pasteurization and sterilization.
