Nutrient salts, oils and organic matter build up on probe faces over time, and a dirty probe reads wrong — which means your whole feed chart is working off bad numbers. This kit gives you both probe cleaners, calibration and storage solutions, and the cleaning tools to bring your readings back to accurate and keep them there.
