General Hydroponics PH DOWN helps you to control pH. It offers premium pH management and buffering for hydroponics, coco and soil.
GHE PH DOWN is made with a blend of three acids commonly used alone in hydroponics to give you all the benefits of each acid, without the disadvantages.
GHE pH Down 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.
This ensures no residue on the surface of your tank from using phosphoric alone in hard water areas. 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.
