GHE pH -: 

Premium pH management and buffering for hydroponics, coco and soil.

Not just a simple acid: GHE pH – makes a real contribution to nutrient solution stability

To make GHE pH – we carefully blend three acids commonly used alone in hydroponics to give you all the benefits of each – without the disadvantages.

GHE pH – uses nitric and phosphoric acids to do the initial heavy lifting of altering your water pH, and the blend of both means no disturbance to your N/K ratios throughout grow and bloom – and no residue on the surface of your tank from using phosphoric alone in hard water areas. Then, with its own special characteristics, organic citric acid takes over to buffer pH changes over time, keeping your nutrient solution more stable, and helping handle calcium excesses in hard water areas.

HOW TO USE:

Warning: Always wear appropriate protection when handling strong alkalis.

To adjust pH: Add to water or nutritive solution as required. Re-test pH and adjust as necessary.
