Bluelab calibration, conductivity and KCl storage solutions are a must in every growers’ toolbox.
A clean probe is an accurate probe. Cleaning the probe surface removes dirt or contamination. After cleaning - calibration (for pH probes) or testing (for conductivity probes) is needed. Bluelab ppm and EC Pens can be calibrated.
Cleaning and calibrating at least monthly will help maintain accurate readings. Accurate readings simplify crop management and provide improved growth.
