The special formula of the pH – solution of GHE provides for the mixing of the three acids that are commonly used in the regulation of the nutrient solution of soilless crops such as phosphoric acid, nitric and citric.

In particular, nitric and phosphoric acid combined together, lower the pH value while maintaining a greater balance to the N / K value of the nutrient solution.

Organic citric acid comes into play to stabilize changes in pH over time, keeping your solution more stable, and helping to manage excess calcium in areas with hard water.

Warning: Always wear suitable protection when handling strong acids.

To change the pH: add as needed to the water or nutrient solution. Test the pH again and correct it if necessary.
