Hy-Gen pH Buffer 4 is important as the lower calibration point in the two point calibration of electronic meters. Regularly calibrate your pH meter with both pH Buffer 4 and pH Buffer 7 calibration solutions to ensure that your meter is operating with precision and accuracy between pH 4 and 7. Some electronic meters require a ‘two point’ calibration. pH BUFFER 4 is important as the lower calibration point in the two point calibration process. This will ensure that meters accurately reflect the true reading at the lower end of the range.

Monitor the pH on a daily basis. As plants grow, demand for nutrients increase. This means the pH can fluctuate and therefore should be tested and adjusted to maintain an optimum working nutrient solution. Nutrient requirements vary from plant to plant; therefore the ideal pH varies from plant to plant also.

The ideal pH range for a nutrient solution is typically between 5.8 and 6.5. A pH value above or below this range can increase the likelihood that some nutrients become unavailable to the plant. A pH value of 6.3 typically works well for most plants.

Some electronic meters require a ‘two point’ calibration. pH BUFFER 4 is important as the lower calibration point in the two point calibration process. This will ensure that meters accurately reflect the true reading at the lower end of the range.
