HY-GEN PH-4 BUFFER SOLUTION

pH BUFFER 4
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.
