Power Si is the original patented form of stabilized, bioavalible silicic acid for crops. Unlike other silica products, we work with the best possible silicic acid matrix (patented!) to ensure superior absorption. Power Si is a proprietary organic biomix containing highly bioavaliable micro and macro nutrients. It is a pure, highly concentrated formula with fast visible effects. It also increases nutrient absorption and bioavailibility of all other nutrients by acting as an efficient transporter. Furthermore, Power Si reduces nutrient salt build-up and dehydration of your crops. Power Si is proven to build stronger cell walls decreasing susceptibility to various diseases resulting in stronger plants and thicker stems. Power Si also corrects and reduces the space between internodes caused by environmental stress and nutrition imbalances improving your crops overall health.
