Pro Powders Silica Pro Potassium Silicate Powder - 20 lb

Soluble Potassium and Silicon for Sturdier Plants - 20 lb Powder

Plants under environmental stress can struggle to hold structure and stay upright through vegetative growth and flowering. This potassium silicate powder supplies soluble potassium (K2O) and plant-available silicon (Si) to support structural integrity, upright growth and stress tolerance. It carries a guaranteed analysis of 33.0% soluble potash (K2O) and 53.0% soluble silica (SiO2), with potassium silicate as the source.

The 20 lb size suits growers who feed silicon regularly across several cycles or run larger rooms and automated irrigation. Hobbyists who want a smaller trial may prefer a smaller container, since this is a bulk-oriented unit.
