Haifa Cal Prime 17-0-0 + 23.5% Ca

Haifa Cal Prime — High-Concentration Calcium Nitrate for Hydroponics & Fertigation

Haifa Cal Prime is the most concentrated calcium nitrate formulation available for professional hydroponic and fertigation programs. Delivering 17% nitrogen and 23.5% calcium (33% CaO) in an anhydrous, near-ammonium-free form (only 0.3% NH₄-N), Cal Prime sets a new standard for precision calcium nutrition in soilless and controlled-environment production systems.

17% more concentrated than conventional calcium nitrate products — meaning less product per tank, reduced transport volume, and lower storage requirements without compromising plant nutrition.

Key Advantages for Hydroponics & Fertigation

• 23.5% calcium (33% CaO) — highest calcium concentration of any major calcium nitrate; more Ca delivered per kg of product
• Only 0.3% ammonium-N — near-zero ammonium prevents pH drift in recirculating systems and eliminates ammonium toxicity risk under high light conditions
• 17% more concentrated — reduced application volumes; fewer deliveries and less storage space required
• 100% water soluble — dissolves completely with no residue; compatible with all drip, NFT, DWC, and injection systems
• Chloride & sodium free — no salt accumulation in recirculating systems; safe for sensitive crops
• Ideal for high-irradiation environments — near-zero ammonium prevents toxic ammonium uptake under intense light conditions

Why Low Ammonium Matters in Hydroponics

In soilless and hydroponic systems, ammonium nitrogen cannot be buffered by soil microbes the way it is in field production. Excess ammonium in the root zone competes with calcium and potassium uptake, lowers solution pH, and can cause phytotoxicity — especially under high light intensity when ammonium uptake accelerates. At only 0.3% ammonium, Haifa Cal Prime virtually eliminates these risks while delivering maximum calcium and nitrogen efficiency.

Ideal Applications

• Recirculating hydroponic systems (NFT, DWC, ebb & flow)
• Greenhouse drip fertigation for tomatoes, peppers, cucumbers, and leafy greens
• High-light greenhouse environments where ammonium toxicity is a concern
• Precision nutrient programs requiring exact Ca:N ratios
• Operations looking to reduce product volume and storage footprint
