High-Analysis Water-Soluble Potassium for Any Growing System

Potassium Chloride (MOP) 0-0-62 is one of the most concentrated and cost-effective sources of soluble potassium available. With 62% K2O and 47% chloride, this fine powder dissolves completely in water — making it ideal for fertigation, drip irrigation, hydroponics, and greenhouse applications where rapid potassium delivery is needed.

A versatile staple in professional nutrient programs, it can also be used to prepare storage and calibration solutions for pH and TDS/EC meter probes.

Key Benefits

• High-Analysis 0-0-62: One of the most concentrated potassium sources available — more K per dollar than most alternatives.
• Fully Water-Soluble: Fine powder dissolves completely with no residue — safe for drip emitters and injection systems.
• Fast Potassium Delivery: Rapidly corrects potassium deficiency and supports fruiting, flowering, and root development.
• Broad Application Compatibility: Suitable for hydroponics, soil, greenhouse, and field crop programs.
• Dual-Use: Can be used to prepare DIY storage solution for pH and TDS/EC meter probes (1g per gallon = 136 ppm K, 124 ppm Cl). Learn how to make your own pH probe storage solution →
