The Product
Not all Calcium Nitrate is created equal. HRSU's crystalline powder delivers precision where granules fail - complete dissolution, exact nutrient concentration, zero clogging.
Applications
Prevents blossom-end rot, tip burn, and calcium deficiencies in tomatoes, peppers, and leafy greens. Compatible with all drip systems. Foliar-grade clarity - no nozzle clogging.
Dissolves at room temperature - ideal for closed-loop NFT, DWC, and aeroponic systems demanding EC precision. Compatible with all A/B nutrient systems.
Chloride-free accelerating admixture per ASTM C494. Reduces initial set time by up to 40%, enabling pours down to –15°C without reinforcement corrosion.
Controls hydrogen sulfide odour in municipal sewers and industrial effluent. Maintains denitrification balance in activated sludge processes.
Latex coagulation, surface treatment in metal industries, and heat-transfer fluid formulations. Consistent industrial-grade batches with COA on every lot.
"We don't just supply chemicals.
We supply confidence."

Common Questions
Calcium Nitrate provides both Calcium and Nitrogen in a water-soluble form. Used in drip irrigation, hydroponic nutrient formulations, concrete accelerating admixtures, H₂S control in wastewater, and latex coagulation.
Powdered Calcium Nitrate dissolves instantly and completely - zero residue. Granules contain binders that clog drip emitters. HRSU's powder achieves 100% dissolution at room temperature.
Yes - it's the foundational component in hydroponic Tank A formulations. Compatible with NFT, DWC, and all standard A/B systems. Keep separate from phosphate/sulfate sources.
