Hy-Gen pH Buffer 4.0 Calibration Solution for pH Meter 

The ideal pH range for a nutrient solution is typicallybetween 5.8 and 6.5. A pH value above or below this range can increase thelikelihood that some nutrients become unavailable to the plant. A pH value of6.3 typically works well for most plants.

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