Original

Power Si Original is a premium stabilized monosilicic acid (orthosilicic acid) supplement formulated with bioavailable silicic acid alongside micro and macronutrients. Unlike potassium silicate products that require soil microbial conversion to become absorbable, Power Si delivers silicon already in the monosilicic acid form that plants take up directly through roots and leaves — achieving results within 24 hours of application.

Plants deposit absorbed silicon in epidermal cells and vascular tissue throughout the plant, creating physically stronger stems, thicker leaves with improved pest and disease resistance, and harder surfaces that make it more difficult for insects and fungi to penetrate. Yield improvements, improved lateral branching, and enhanced trichome formation are commonly reported. Power Si doesn't raise pH and is tank-stable without creating unwanted residue in reservoirs.

Apply throughout vegetative and flowering phases in any growing system. Pairs effectively with FloraFlex nutrients as a standard part of the feeding program. No pH adjustment required. Made by Power Si, Belgium — the original high-purity monosilicic acid for horticulture.
