The Growlink batch tankLINK (GL-LINK-BATCH) is a dedicated nutrient-tank monitoring and automation controller for continuously tracking EC, pH, temperature, and tank level. It can trigger automated refills based on tank-level thresholds, store sensor data locally, provide configurable high/low alerts, and send data to Growlink OS for centralized monitoring and crop-steering analysis. It can also operate independently over Wi-Fi when a Growlink HUB is not present.

Key Advantage: The batch tankLINK combines four critical nutrient-tank measurements with local data logging, threshold alerts, and automated refill capability in one controller. When connected to Growlink OS, the tank data can be combined with irrigation and canopy data to support centralized monitoring and closed-loop crop steering.
