For your plants to be truly happy, the pH level of the nutrient solution needs to be slightly acidic; the ideal being between 5.5 and 6.5.
Our fertilizers contain pH-regulating elements that allow your solution to always remain stable. In practice, and for several reasons, this stability is unfortunately not always ensured: When the water is not of good quality, when the supports used have unstable pH values, such as for certain rock wools and clay and when the plant’s growth rate is such that rapid nutrient uptake unbalances the nutrient solution.
Our pH Indicator Test is perfect for quick testing.
To know the pH level of your nutrient solution, fill half of the vial included in the kit and add 3 drops of our indicator.
Compare the color thus obtained with those of the chart provided for this purpose.
You can do over 200 tests per vial at an unbeatable price. Reliable, easy to use and inexpensive.
