Emerald Harvest Sturdy Stalk 1 Gal

 Build up your plant cell walls to support maximum yields with Sturdy Stalk, a potassium silicate supplement from Emerald Harvest. The silica in this fortifying formulation bulks up interior plant structures and grows hardy, stress-resistant plants so that they spend more of their energy creating blooms and buds. This results in a productive, vigorous garden with heightened resistance to pests, insects and pathogenic airborne and waterborne diseases.
