Power Si is a patented form of silicic acid for crops.
Unlike other silica products, we work with the best possible silicic acid matrix (patented) to enable superior absorption. Power Si is a proprietary organic biomix containing highly bioavailable micro and macronutrients. It is a pure, highly concentrated formula with fast visible effects. Power Si also increases nutrient absorption and bioavailability 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 corrects and reduces the space between internodes caused by environmental stress and nutrition imbalances improving your crops overall health.
