This new concept of pH control will allow you to adjust and stabilize your pH level even in the presence of fast-growing plants.
The degree of acidity or alkalinity of a solution plays an important role on the solubility of the mineral salts and on their absorption by the plant. But in terms of pH, there is no ideal level: a high level favors the cationic absorption and a low level favors that of the anions. Any decision therefore remains a compromise.
In addition, everyone is not the same opinion: some researchers do not see any difference between levels ranging from 4.9 to 6.8! Others are much more picky and adapt their levels to each plant.
It is generally recommended to stay between 5.5 and 6.5. Here we prefer to stay in the lower bracket, and cautiously fluctuate between 5.5 and 6.2.
An ideal pH regulator is a solution you use once: when you start your system. We are not quite there yet, at least not in all situations or with all the fertilizers. But in the tests we do in our greenhouse, where we use our pH regulator with Flora Series and Mineral Magic, we kept the same pH level for several weeks.
In some systems, the pH gradually decreased and a little pH Up restored its balance. In others it stabilized perfectly around a beautiful 6.0.
PH Down - pH Buffer contains organic regulators
Unlike commercially available regulators, pH Down is not a simple acid. It is a precise formula, a balanced mixture of acids and organic regulators that stabilize the pH while regulating the calcium level (this is particularly useful in case of hard water).
It is used when preparing the nutrient solution to lower the pH.
This one remains stable until the renewal of the solution, and only requires occasional readjustments.
PH Up contains silicate
To raise the pH level, this solution is particularly useful for those who use reverse osmosis filters or demineralised water.
pH Up contains silicate, an element whose deficiency can be a limiting factor in hydroponics. Because of its limited solubility, it is difficult to put enough in the nutrient solution.
That's why we incorporate them into our products whenever we can.
