Nutrifield Si-Phi ISN and boosts performance across soilNutrifield SiPhi is a premium plantcare biostimulant that combines potassium silicate (Si) and potassium phosphite (Phi) to strengthen your plants and boost resilience. The silicon component supports and reinforces cell walls, helping plants better withstand heat, drought, and environmental stress. The phosphite works as a metabolic stimulant (not just a nutrient source), encouraging increased stress tolerance, healthier growth, and improved vigor.
