Growlink LINKS batch tankLINK Nutrient Tank Monitor & Controller

The Growlink LINKS batch tankLINK keeps your nutrient reservoirs monitored and under control, tracking tank levels and driving batch mixing so you're never caught guessing how much feed is left mid-cycle. Why growers choose batch tankLINK Automated tank monitoring: Continuous visibility into nutrient tank levels, so refills happen on your schedule, not in an emergency. Batch mixing control: Drives batch tank fill and dosing cycles automatically as part of your wider irrigation setup. Growlink Copilot ready: Feeds tank-level data into Growlink Copilot alongside your valveLINK and canopyLINK sensors for closed-loop automation. Rugged, durable build: Built for the same demanding commercial and home-grow environments as the rest of the LINKS range. Part of the Growlink LINKS Ecosystem LINKS is Growlink's modular grow-room hardware system: small, purpose-built devices that each do one job well, and click together into a whole-facility control network. batch tankLINK (this device) handles nutrient tank monitoring and batch mixing, working alongside valveLINK for irrigation and canopyLINK for climate and substrate monitoring. Every LINKS device can run wirelessly on its own over Wi-Fi, but connect them to the HUB over a wired RJ-45 connection and you unlock whole-room automation, longer signal range, and the ability for the HUB to power and enable additional LINKS hardware across the facility.
