Save time and effort with the Bluelab Guardian Monitor
With the Bluelab Guardian Monitor, you will be able to continuously monitor the key parameters of pH, EC and temperature. There’s no need for manual measurements and spot checks; instead, you will only need to adjust for pH and nutrient.

When you consistently track the three fundamental parameters of nutrient uptake, you’ll be able to spot any fluctuations, allowing you to solve issues as and when they happen. After all, when you keep these parameters steady, you’ll end up with healthier plants.
