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.
