NH Phosphoric Acid 85% (Food Grade) is a premium-grade acidifier formulated for hydroponic systems, greenhouse production, and food-safe crop applications. It is used to lower the pH of nutrient solutions to maintain the ideal range for nutrient availability. When the pH is kept within the right zone, plants absorb nutrients more efficiently and develop more consistently.
This formulation contains phosphorus, which plays a central role in root growth, flowering, and energy conversion through ATP (adenosine triphosphate). It provides a nutrient benefit while adjusting solution acidity, supporting both health and productivity.
As a food-grade product, NH Phosphoric Acid 85% is suitable for use in systems that cultivate crops like lettuce, herbs, and tomatoes. Because it’s highly concentrated, it’s also cost-effective. Just a small amount is enough to achieve target pH levels.
Benefits:
  • Fast-acting pH adjustment
  • Supplies phosphorus (P) to nutrient solutions
  • Helps restore nutrient availability in high-pH conditions
  • Works across various hydroponic systems including DWC, NFT, coco, and rockwool setups
  • Approved for use in food production systems with proper handling
Usage Tips:
  • Add acid to water slowly, never the reverse
  • Measure with a calibrated pH meter
  • Start with low doses and increase as needed
Available Sizes:
  • 120 mL
  • 500 mL
  • 1 Liter
  • 4 Liters
