Silica
Silica is important for the health of plant stalks and roots. Supplementing with silica gives plants more food to strengthen cell walls, making both stems and shoots more resistant to pests, disease, and general wear and tear from wind and rain. This means better heat resistance, drought resistance, cold stress tolerance, and better leaf exposure to light. Silica can be watered directly into soil or can be used as a foliar spray for immediate results. For supplements that are light in macronutrients NPK, silica can be used throughout the growing cycle.
