PH METERS - Всичко за вашите растения!
The first step to maintaining a stable pH value is regular control and measurement using pH meters. We offer instruments for accurate measurement of the pH of a solution or substrate ADWA pH meters BlueLab, GIB, spare parts and accessories.
In the growth phase, the pH usually rises due to the fact that the roots secrete substances that increase the pH. The opposite process occurs in the flowering phase, when substances released by the roots lower the pH values. If you provide the plants with specialized nutrition for both phases, you will help maintain a stable pH.
The pH value can also be affected by the presence of trace elements in the water. In the case of hard water, the pH of the watering will rather increase after mixing with fertilizers. On the contrary, with soft water there is a risk of a decrease in the pH value. In areas with soft water, it is more appropriate to prepare a nutrient solution with a higher pH value of 5.8-6.2. At a lower pH value, some substances (iron, manganese, etc.) dissolve more easily and can thus oversaturate the plant.
