Premium pH management
There is no such thing as an ideal pH. High values help cation uptake and low values help anion uptake: every fixed pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2.
GHE pH Down:
Premium pH management and buffering for hydroponics, coco and soil.
Not just a simple acid: GHE pH Down makes a real contribution to nutrient solution stability
To make GHE pH Down we carefully blend three acids commonly used alone in hydroponics to give you all the benefits of each - 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 - 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.
GHE pH Up:
Premium pH management and silica source for hydroponics, coco and soil.
Control pH and boost silica levels at the same time
Whilst raising pH level may seem crazy to growers in hard water areas, it€™s a real issue with very soft water or when using reverse osmosis. GHE pH Up allows that adjustment, and offers a good source of available silicate - which is often deficient in Hydroponics, due to its very low solubility. Proper silicate levels make a big contribution to plant health and so we include it in products whenever we can.
Dry pH Down:
Unique dry powder pH management solution for hydroponics, coco and soil.
The only dry powder pH adjuster on the market today
A unique product in the industry: inert when dry, GHE Dry pH Down becomes a potent acid when mixed with water.
pH regulation is an essential practice for all growers: it makes mineral salts available and stabilizes chelates, but for shops who offer mail order, sending liquid acids by post can be a risky matter - sometimes restricted by postal authorities. GHE Dry pH Down avoids these problems making shipping and transport much easier.
As well as adjusting pH regulation, GHE Dry pH Down can be used (at high concentration) to clean and disinfect lines and systems, at low concentration use as a foliar spray to clean pesticide residue from leaves, and finally, it also gives a nutritive boost to plants by providing:
