GHE pH Down Dry

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.

Base formulated using potassium hydroxide, organic citric acid and potassium carbonate.

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:

  • Nitrates, in a form that supports growth without compromising flowering.
  • Phosphates for strong flowering, root health, lush foliage and harmonious growth. 

pH- powder becomes potent pH reducer as soon as it's mixed with water. It is used to lower the pH level during all of the plants life cycle and to clean substrate, systems and parts.


To reach a pH of 5.0 to 6.0 in most waters: In the solution use 1g for 5 to 6 litres. (0.2g/litre)

For foliar spray: use 1g for 10 litres

To clean growing systems, substrates and parts: dilute 1g for 1 litre. Let it run overnight and rinse well.
