G.H.E - PH-Up

The pH Up contains silicate
To raise the pH level this solution is especially useful to growers using Reverse Osmosis or demineralized water.This new version contains silicate to improve your plant's environment.
Silicate deficiency can be a limiting factor in hydroponics. Because of its low solubility, it is difficult to put enough of it in the solution.This is why we incorporate it in our products each time it is possible.
A good pH control solution is one that you use only once: when you start your system. Well,we don’t claim that we got quite that; not in every situation and with every nutrient. But in the controls that we have done in our greenhouse, using the pH Down in combination with our Flora-series nutrient and Mineral Magic, we have grown plants for weeks without having to readjust the pH. In some of the smaller systems the pH would drift slowly down, and adding a little of our pH Up would bring it back to the desired range. In others, the pH would stay very close to a beautiful 6.0.

There is no such thing as an ideal pH. A high range favors cation intake and a low one favors anion intake. So every chosen pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advise is to stay on the low side: from 5.5 to 6.2.
