Measures 3 critical parameters: pH, conductivity and temperature - Seasonal changes, sunlight hours, wind, inherent plant growth; from vegetative to fruiting; are all influencing factors to plant growth success.
More importantly...these parameters change the plants uptake and need of water and specific nutrient elements.
The Bluelab Guardian is a constant indicator of the desired levels of EC, pH and temperature, enabling the grower to optimise these parameters as the crop progresses through each growing phase.
