As growers, we always have a wish list of things that would make life easier. On top of the list is a pH buffer that would work so well that you could go on a 2-week holiday and come back to the same pH in your nutrient solution. The problem is that this can be done only with a poor nutrient when there is not much action in your solution and your plants grow at an average rate. In presence of fast growth, with the removal of a large number of ions and all the complex interactions in the solution, such stability is out of the question.Today we are not helpless anymore, and we can achieve a satisfying stability… as well as other benefits.
A good pH control solution is one that you use only once: when you start your system. Well, GHE doesn’t claim that they've got quite that; not in every situation and with every nutrient. But in the controls that GHE have done in their greenhouse, using the pH Down in combination with Flora-Series nutrient and Mineral Magic, they 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. GHE's advise is to stay on the low side: from 5.5 to 6.2.
The pH Down - pH Buffer an organically buffered solution.
Unlike the pH regulators generally available on the market, pH Down is not a common acid. It is a precise formula that regulates, feeds, and buffers your nutritive solution all at once.
Together with a balanced blend of acids,GHE have incorporated buffers to stabilize pH and help control Calcium in hard water situations.
