Super Silica Is a highly concentrated agricultural grade liquid silica nutrient. When SUPER SILICA is compared to most other brands, when applied at an equivalent ml/L usage rate, it proves to provide significantly more ‘Plant Available Silicon’ (PAS) to hydroponic solutions.
- NPK 0 – 0 – 20 as K2O
- 31 % SiO2 (14.95% Si)
- 14.1% Plant available Silicon (PAS) determined by the American Association of Plant Food Control Officials (AAPFCO) approved 5-day method
Recommended usage rate 0.25ml/L
Usage at 0.25ml/L results in approx. 66 ppm K and 59.8 ppm Si in solution
