There is no such thing as an ideal pH. High values help cation uptake and low values help ion uptake: every fixed pH is a compromise. The usual safe range is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2.
Not just a simple acid: GHE pH - helps nutrient solution stability
We carefully blend three acids used alone in hydroponics to give you all the benefits of each.
GHE pH - uses nitric and phosphoric acids to do the initial heavy lifting of altering your water pH. The blend of both means no disturbance to your N/K ratios in 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 mix more stable, and helping handle calcium excesses in hard water areas.
Need PH Up?
Add to water or nutritive solution as required. Re-test pH and adjust as necessary.
