Si-Phi is a synthetic blend of potassium silicate (Si) and potassium phosphite (Phi). Silicate is a bioavailable form of the trace mineral silicon, and phosphite
Si-Phi
Derived from: Monopotassium phosphite, potassium hydroxide, potassium silicate
Si-Phi is part of the Nutrifield Plant Health Enhancer Range, formulated to reinforce plant structure and support physiological resilience under high-intensity cultivation conditions.
The formulation combines bioavailable silica with potassium phosphite in a dual-action approach that extends beyond conventional silica supplementation. Silica is deposited in cell walls and epidermal tissues, reinforcing structural integrity, increasing stem strength, and improving the plant's capacity to support heavy floral loads while maintaining efficient water and nutrient movement. Potassium phosphite engages plant signalling pathways associated with stress response and metabolic regulation, supporting physiological stability under demanding conditions, including high light intensity, elevated EC, and environmental fluctuation.
The clean, stable formulation integrates readily into intensive feeding programs across hydroponic, coco, and soil systems. The result is improved structural integrity, enhanced stress tolerance, and more consistent crop performance across both vegetative and flowering phases.
As part of the Nutrifield Plant Health Enhancer Range, Si-Phi provides the structural and physiological resilience that underpins stable, high-performance cultivation.
