Powder for pH adjustment GHE Dry pH Down 250 g

Pure, concentrated and harmless. PH regulation is an essential practice for the plant grower: it enables mineral salts availability and chelates stability, two primary conditions for a good absorption of nutritive elements by the plant. To do so, different brands of acids are manufactured in the industry, some of them very concentrated and more or less dangerous, depending on their formulation. In several countries, like Switzerland for instance, the law restricts sales and handling of these products. So, to be able to sell them, the storeowner is submitted to a series of mandatory requirements. Moreover, for stores who do mail orders, sending liquid acids by post is a dangerous and risky matter, sometimes restricted by the postal authorities. To address both problems our researchers looked for a product that would be as efficient as our traditional liquid pH Down, while eliminating the dangers controlled by the legislator. Today at GHE we are happy to offer you our “Dry pH Down”, a new concept in pH regulation, and a unique product in our industry. Dry pH Down is quite a peculiar product : as long as it stays dry it is harmless, easy to handle and non-toxic. But as soon as it is mixed with water, it becomes a potent pH reducer. This new concept in pH control will allow you to adjust your pH, specially in presence of fast growing plants.

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,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.
