Power Si is the original patented form of stabilized, bio-available silicic acid for crops. It is pure, highly concentrated, and produces fast, visible effects. Power Si increases the absorption of nutrients while reducing nutrient salt build-up and moisture dehydration of your crops. Power Si is proven to build stronger cell walls, decreasing susceptibility to various diseases and resulting in stronger plants, thicker stems, and increased dry weight. This formula also controls and reduces the space between internodes caused by environmental stress and nutritional imbalances. Power Si is suitable for all cultivation systems and can be used with any other nutrient system on the market.
