PH 4.01 calibration solution - 250ml

Growth Technology's 250ml Ph 4.01 Calibration Solution is a handy liquid used to calibrate electrodes and digital Ph meters to a value of 4.01.

It is advisable to measure the ph of the water every time the vegetable is fed, after the substances or the nourishment have dissolved well.

The pH measurement provides the value of the acidity and basicity of the water, to ensure that it takes the correct absorption of all the microelements and changing the value according to the growth and genetics of the plant. Generally, as far as hemp is concerned, the perfect pH measure is between 6.0 and 6.5, slightly more acidic in the vegetative phase of the plant and on the reverse, tending towards basicity at the time of flowering.

How to properly use Growth Technology's Ph 4.01 Calibration buffer Solution

1. Fill the appropriate "measure" cap with the solution

2. Immerse the electrode

3. Adjust the calibration screw with the screwdriver provided until the display indicates the ph value of the calibration solution (ph 4.01).
