Bluelab Guardian


The Bluelab Guardian Monitor measures all three critical parameters to successful growth: pH, conductivity and temperature.

As the environmental factors such as sunlight hours, wind, inherent plant growth change so do the plants uptake and need of water and specific nutrient elements. The Guardian is a constant indicator of the changing desired levels of pH, EC and temperature by the plant throughout each growing phase. It effectively removes the complexity of how each parameter relies on each other for outstanding growth.

A flashing display on the screen indicates when one parameter moves away from the ideal allowing the grower to quickly and effectively compensate. 24 hour monitoring and a 24 hour alarm system mean less risk of crop failure, less risk of disease due to imbalances and no more test strips, manual meters or constant checking.
