Future Harvests’ Plantacillin contains beneficial Bacillus subtilis GB03, a naturally occurring bacteria that colonizes and lives on plant roots and root hairs. Bacillus subtilis GB03 is gram-positive (spore producing), making it extremely persistent and able to withstand stressful conditions like heat, drought, and cold. Plantacillin’s non-clogging, non-abrasive liquid formulation also includes a food source to ensure the survival of the GB03 once they are applied. Plantacillin is 100% natural, and contains no chemicals. What does this mean for you and your plants? Well, to start with, you’ll get some secondary benefits that you wouldn’t when using chemicals. For instance, it is a known fact that the use of chemical products will actually prune the roots of your plants. In stark contrast to chemical fungicides, Plantacillin actually encourages stronger, denser root mass and length! That is because Bacillus subtilis GB03 excretes auxin-like substances that encourage such growth. The product is also easy to use. Plantacillin can be reservoir-mixed with fertilizers without detrimental effects to the product.
