Description

The Bluelab Guardian Monitor constantly measures conductivity, pH and temperature levels, and displays it in an easy to read LED.

Many factors determine how fast plants take up nutrients; season, stage of growth, temperature, and available light, just to mention a few. And with these variables the critical elements of the hydroponic nutrient can readily change. The Bluelab Guardian monitor makes the task of balancing these changes easier.
