Silica-based nutrients can have Silicon (Si) in various forms like silicic acid and silicon dioxide. It is the only nutrient which is not harmful when overfed. Silicic acid is the most bioavailable form of silicon that strengthens cell walls, increases nutrient uptake, and increases the immune response improving resistance to heat, cold, drought, and pests. Silicon is also one of the best ways to increase calcium availability in the form of silicic acid.

Benefits of Si

increased disease resistance
increased resistance to pathogenic airborne fungi like Botrytis
increased resistance to waterborne pathogens
increased resistanceto insects/pests
increased strength in cell structure
increased stress tolerance
increased drought tolerance
increased salt tolerance
increased yields
