Description
Nutrifield SI-PHISi Phi is a synthetic blend of potassium silicate (Si) and potassium phosphite (Phi). Silica supports and strengthens cell walls, and promotes tolerance to heat and drought stress. Occasional or prolonged high temperatures can cause different physiological and biochemical changes in the plants. These variations effect plant growth as well as development and reduced yield and quality. Use Si Phi throughout the entire grow cycle to ensure plants thrive
