Power Si Original 20L is a concentrated, commercial-grade silicic acid formula for serious growers who want consistent results at scale. It's made with patented, bioavailable silicic acid and essential nutrients like boron and molybdenum to help plants absorb nutrients better, build stronger structures, and perform under stress. This 20-liter size is ideal for large-scale farms, greenhouses, or high-output cultivation. Power Si improves root development, strengthens stems, and supports overall crop health while reducing salt buildup and water loss. It's pH-neutral, tank-stable, and fully compatible with any nutrient or crop protection program. Dilution Rate: Mix 0.5 mL per gallon of water.
