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.

The Guardian removes the complexity of how each parameter relies on each other for outstanding growth.

Our innovative monitor is a new method to help guard the success of your crops with immediate and accurate results.

A flashing display lets you know if one parameter moves away from the ideal, allowing you to make the required adjustments quickly and effectively.

With our Guardian monitoring your crops 24 hours a day with a built in alarm system there is;
