To produce Terra Aquatica pH-, we have carefully combined three commonly used acids separately in hydroponics; With this we can offer you all the benefits of each one of them avoiding their disadvantages.

Terra Aquatica pH- uses nitric and phosphoric acids to do the initial hard work of changing the pH of water and the mixture of both acids supposes the null alteration of the NK proportions during the growth and the bloom, plus avoid any residue on the surface of your container by using phosphoric acid only in areas of hard water.

Then, with its special characteristics, organic citric acid takes over to buffer the changes pH over time, thus keeping your nutrient solution more stable and helping to manage excess calcium in hard water areas.

How to use:

• Add as much pH- or pH+ to the water or nutrient solution as needed.

• Check the pH again and adjust if necessary.

• Warning: Always wear proper protection when handling strong acids/alkalis.
