Depending on the phase in the growth cycle, there may be fluctuations in the pH value, which can lead to disruption of the plant?s nutrient uptake. This can result in a strongly or mildly-presenting nutrient deficiency. Therefore, you should ensure that the pH value remains as stable as possible when cultivating plants.

This kit allows you to determine the pH value of irrigation water quickly and reliably. The contents of this pH testing kit are sufficient to carry out around 500 tests.

...

Soil testing kit for easy and accurate measurement of the pH value of the soil (e.g. to determine if there is a need for lime). Based on a colour reaction, even non-chemists can carry out this test in a matter of minutes.

GHE pH Down is used to reduce the pH value of "hard" water, because most crops require an optimal pH value for nutrient uptake. However, tap water in many countries is often inconsistent in this respect. In most cases, the water is too "hard" (high pH value, a lot of limescale is formed), which requires manual reduction of the pH value (the water is ?acidified?).
In addition to simple acids, this pH Down also contains a mixture of organic buffer substances, which means that the pH value is kept consistent in the long term, and the calcium content is reduced.

GHE pH Up is used to increase the pH value of water. GHE pH Up is used to increase the pH value of "hard" water, because most crops require an optimal pH value for nutrient uptake. However, tap water in many countries is often inconsistent in this respect, so pH correction is essential. In most cases, the water is too "hard" (high pH value, a lot of limescale is formed), which requires manual reduction of the pH value (the water is "acidified").

The pH control system from Advanced Hydroponics is one of the most flexible available and is also fully compatible with fertiliser systems from other manufacturers. In addition to a universally-applicable pH Up (increases pH value), Advanced Hydroponics also offer two different pH Downs. The reason for this seemingly complicated solution is that plants metabolise pH correction elements differently in different stages of their life cycle. As such, the pH correction of the irrigation water or nutrient solution can be optimised by using different products that take these conditions into account.

The digital pH meter ADWA AD11.
Measure pH values easily, safely, and reliably.

The electronic pH meter AD11 by ADWA enables uncomplicated testing of the optimal pH value of irrigation water both before and after adding fertiliser. The pH value defines how "acidic" or "alkaline" a fluid is, i.e. how well other substances can dissolve in it. As such, the fluid should have an ideal pH value so that the added nutrients can dissolve optimally, as they are otherwise inaccessible to the plant. (Roots cannot "directly" take in nutrients, only in a solution with water).

We know pH levels can be the difference between a great crop and well, a disaster. Measuring and adjusting nutrient solution levels constantly can be time-consuming. And let?s face it; you have better things to do.

Sometimes the more you know, the better. And when it comes to managing the pH of your nutrient solution, exact knowledge makes a world of difference.
