Pro Powders Silica Pro Potassium Silicate Powder - 50 lb

Soluble Potassium and Silicon for Sturdier Plants - 50 lb Bulk Supply

Growers who want stronger structure and better stress tolerance need a silicon source that dissolves cleanly and fits an existing feed schedule. Silica Pro is a potassium silicate powder that supplies soluble potassium (K2O) and plant-available silicon. It carries a guaranteed analysis of 33.0% soluble potash and 53.0% soluble silica, so you can dose from a stated analysis.

The 50 lb size suits growers who use silicon supplements regularly across several rooms, reservoirs or irrigation lines. Smaller gardens may find it more than they need, while larger and automated operations will value a bulk supply of one product.
