Blue lab Guardian Monitor



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.
