Boca Hydro Sulfate of Potash 0-0-50

Boca Hydro Sulfate of Potash (SOP) 0-0-50 is a high-purity, chloride-free source of 50% Potassium (K₂O) and 18% Sulfur (S). It delivers two essential nutrients critical for strong flowering, fruiting, root development, and disease resistance—making it ideal for all crops, including citrus, tomatoes, leafy greens, and flowering ornamentals. Our ultra-refined, water-soluble SOP dissolves quickly and is safe for hydroponics, soil applications, foliar spray, and fertigation systems.

Unlike potassium chloride (Muriate of Potash), SOP is low in salt index and free of harmful chlorides, making it a superior choice for sensitive crops and high-performance growers.
