Rock wool blocks that are used both to germinate and transplant plants with bare roots or plants grown en block. With 40 mm diameter hole.
When plants grow, the pH can increase, causing root activity due to the absorption of nutrients. If the pH rises, it is a good sign that indicates that the plant is growing.
In many plants in a state of flowering or fruiting, the pH may drop slightly, which indicates that flowering fertilizers should be used. Although the pH may vary occasionally within the rock wool, it is most important to maintain the appropriate pH level in the nutrient solution of the deposit constantly.
