Hy-Gen pH BUFFER 4

The optimal pH range for a nutrient solution is generally between 5.8 and 6.5. A pH outside this range can cause certain nutrients to become unavailable to plants. Most plants thrive at a pH of around 6.3.

Many electronic pH meters require a ‘two-point’ calibration for accuracy. **pH BUFFER 4** is crucial as the lower calibration point in this process, ensuring that meters provide precise readings at the lower end of the pH scale.
