pH pen calibration solutions

Calibrating your pH pen is like changing your toothbrush.

Growers are advised to calibrate their pH pens every 6 months. Nothing beats a bad harvest because of a miscalibrated EC meter.

Purchase our conveniently bottled calibration solutions (6.86, 4.01, 9.18) to ensure your pH pen sensors are in tip-top condition and that your plants are getting the right pH concentrations for optimum growth.
