Power Si Original 250ml
Best silica supplement for growers seeking stronger stems and improved resilience.
Power Si Original is a concentrated silica biomix designed to enhance plant health and nutrient absorption. This pure, highly concentrated formula delivers fast, visible results by increasing nutrient uptake and bioavailability. Silica acts as an efficient transporter, helping to reduce salt buildup and dehydration in crops. It strengthens cell walls, leading to more robust plants with thicker stalks and stems, while also correcting internode elongation caused by environmental stress and nutrient imbalance. This product is ideal for growers seeking to improve plant structure and resilience.

Know before you buy
Power Si uses a proprietary, highly bioavailable biomix that allows plants to absorb silica more efficiently than traditional potassium silicate products. This formula is designed for rapid uptake, leading to faster structural improvements in stalks and stems.
Yes, Power Si Original is formulated for use in both the vegetative and flowering stages. It is effective year-round, regardless of the season, to support consistent plant resilience.
The standard application rate is 0.5 mL per gallon of water. Because it is a highly concentrated formula, it is important to measure carefully to ensure you do not exceed the recommended dosage.
Yes, Power Si is specifically designed to correct internode elongation caused by environmental stress. By strengthening cell walls, it helps keep plants compact and structurally sound.
Yes, the silica in this formula acts as an efficient transporter that helps reduce salt buildup. This improves the overall health of the root zone and prevents nutrient lockout caused by excess salt accumulation.
