HY-GEN PH BUFFER 4 1LTR

Description

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.
