Haifa SOP GG is a greenhouse-grade potassium sulfate fertilizer with 51% soluble potash, 18% sulfur and no nitrogen. It dissolves fully for fertigation, hydroponics and blended feeding programs. The zero-nitrogen formula lets growers push potassium during flowering, fruit set and sizing without adding nitrogen. It suits greenhouse and intensive growers who need clean, precise nutrient control, and it competes with other fully soluble potassium sources on purity and chloride-free nutrition.

Haifa SOP GG 0-0-51 is a greenhouse-grade sulfate of potash (potassium sulfate) fertilizer. It is fully water soluble and supplies 51% soluble potash (K₂O) and 18% sulfur (S). It contains 0% nitrogen.
Because it adds potassium without adding nitrogen, it can raise potassium levels in a feeding program without changing nitrogen levels. This suits stages with high potassium demand, such as flowering, fruit development, fruit sizing and finishing. The sulfur content supports crops that need additional sulfur.
It is suitable for fertigation of all crops and for preparing fertilizer blends and liquid fertilizer solutions. It has a low chloride content and a low salt index, which suits salt-sensitive crops and high-frequency irrigation systems. It is used in greenhouse, hydroponic and intensive crop production.
