Hy-Pro pH- Nitric Acid – Nitric Acid-Based pH Adjuster for Nutrient Solution

Hy-Pro pH- Nitric Acid – Nitric Acid-Based pH Down for Nutrient Solution

Hy-Pro pH- Nitric Acid is a nitric acid-based pH down product used to lower the pH of the nutrient solution to the optimal range of 5.5 to 6.0, where plants absorb nutrients most effectively. It is suitable for soil, coco, and hydroponic cultivation and can be used during all growth stages.

This is a highly concentrated product, so it should be added drop by drop while constantly checking the pH with a pH meter. It is recommended to first adjust the EC—that is, mix all the nutrients in the reservoir—and then correct the pH at the end, once the solution is complete.

Caution: This is an acid. Always handle it with gloves and safety goggles, keep it out of reach of children, and never mix it directly with other concentrated correctors.

Key Features

• Nitric acid base: pH down product formulated with nitric acid.
• Target range 5.5-6.0: brings the nutrient solution to the optimal absorption range.
• Suitable for soil, coco, and hydroponics: one pH down product for any cultivation system.
• Use in all stages: can be used throughout the entire cycle, from growth to flowering.
• Highly concentrated: only minimal amounts are needed, so it offers great value per container.
• Two sizes: available in a 500 ml bottle and a 5-liter container for large reservoirs.

How to Use

• First adjust the EC: mix all fertilizers in the reservoir and stir well before adjusting the pH.
• Correct the pH at the end: once the nutrient solution is complete, measure the initial pH.
• Add drop by drop: the product is highly concentrated; add small amounts and stir after each addition.
• Measure constantly: check the value with a pH meter after each dose until it is between 5.5 and 6.0.
• Protective gear required: always handle with gloves and safety goggles and avoid splashes.
• Do not mix: never mix it directly with other concentrated correctors and keep it out of reach of children.

Your satisfaction is our priority.

1. First mix all the fertilizers in the reservoir and adjust the EC of the nutrient solution.
2. Put on gloves and safety goggles before opening the container.
3. Measure the starting pH of the solution with a pH meter.
4. Add the pH- Nitric Acid drop by drop, in very small quantities, and stir the reservoir after each addition.
5. Measure again after each dose until the pH is between 5.5 and 6.0.
6. Close the container tightly, store it out of reach of children and never mix it directly with other concentrated correctors.
