Question
What is the importance of pH measuring?
Answer
pH has a great influence on the availability of the different nutrient elements. Therefore be sure the pH is always in the right range. The best availability range in the substrate is from 5.2- up to 6.2.
But CANNA recommends a different range for each type of substrate:
| TERRA | 5.8 – 6.2 |
| COCO | 5.5 – 6.2 |
| Others | 5.2 – 6.2 |
