Bluelab Hydroponics Medium, Nutrient Solution and Potting Soil Mix Multimedia pH Measuring Meter.

The potential hydrogen, pH, plays an important role in growing, the correct balance ensures that all the essential nutrients dissolved in water to feed plants remain soluble and available to plant roots for absorption.
This pH meter is built with a reinforced tip to measure pH of the root zone in a variety of growing media such as rock wool, coco coir, other growing substrates and aggregates, potting mix and soil, and the nutrient solution.
