Build Inner Strength Build up your plant cell walls to support maximum yields with Sturdy Stalk, a potassium silicate supplement from Emerald Harvest. This Fortifying formulation strengthens cell walls leading to bulkier interior plant structures, promoting plant health through hardier, stress resistant plants. Sturdy Stalk’s key ingredient—silica—fortifies your plants and enriches the internal structures needed to support top-heavy plants laden with flowers and fruits. Because it strengthens cells, silica helps plants withstand environmental and other stressors, 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. Sturdy Stalk contains potassium silicate, providing silicon to strengthen cells whilst potassium helps your plants get the most benefit from photosynthesis, no matter with what light or where your plants are cultivated. Equally important in outdoor and soilless gardens, potassium is essential for strong vegetative growth and yields.
