Haifa SOP GG 0-0-51 — Potassium Sulfate

Haifa SOP GG 0-0-51 — Greenhouse-Grade Water-Soluble Potassium Sulfate

Haifa SOP GG is a premium greenhouse-grade potassium sulfate delivering 51% K₂O and 18% sulfate sulfur in a fully water-soluble, chloride-free formulation. Produced by Haifa Fertilizers, SOP GG is specifically engineered for hydroponic and fertigation systems — dissolving rapidly and completely with no residue, and providing a slightly acidic pH that helps prevent irrigation line blockages and improves phosphate and micronutrient availability in alkaline water.

Nitrogen-free and sodium-free, Haifa SOP GG allows precise potassium management without affecting the nitrogen balance of your nutrient program — ideal for fruiting and finishing stages where high K:N ratios are required.

Key Features

• 51% K₂O — high-analysis potassium for efficient delivery per kilogram of product
• 18% sulfate sulfur — immediately plant-available; supports protein synthesis and quality
• Nitrogen-free — precise K control without affecting N:K ratio
• Chloride and sodium free — safe for recirculating systems and chloride-sensitive crops
• Acidic pH in solution — helps prevent line blockages; improves P and micronutrient availability
• 100% water soluble — dissolves completely; no residue or clogging
• Greenhouse grade — produced to strict purity standards for professional horticulture

Applications

• Hydroponic nutrient programs — NFT, DWC, ebb & flow, drip
• Greenhouse fertigation for tomatoes, peppers, cucumbers, and specialty crop
• Fruiting and finishing stage potassium boost
• Alkaline water correction — acidic pH improves nutrient availability
• Chloride-sensitive crop production
