Description
The Growlink LINKS nutriLINK is a precision nutrient delivery controller built for growers who want repeatable, hands-off dosing. Eight universal outputs drive your dosing pumps, while integrated sensor inputs for pH, EC, and flow keep every feed on target — all coordinated through Growlink OS.
Why growers choose nutriLINK
- Eight universal outputs: Run up to eight dosing pumps from one controller, covering every nutrient, additive, and pH adjuster your recipe needs.
- Integrated pH, EC & flow sensing: Built-in sensor inputs keep dosing decisions grounded in real, live feed data rather than a fixed schedule.
- Customisable dosing programs: Build recipes tailored to each crop stage and let nutriLINK handle the repeat work.
- Growlink Copilot ready: Feeds live dosing and sensor data into Growlink Copilot for automated, data-driven fertigation decisions.
- Rugged, durable build: Engineered for demanding commercial and home-grow environments where reliability matters more than anything else.

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. nutriLINK handles nutrient dosing — eight universal outputs for pumps plus sensor inputs for pH, EC, and flow — feeding dosing data straight into Growlink OS for automated fertigation. Every LINKS device can run wirelessly on its own over Wi-Fi, but connecting to the HUB over a wired RJ-45 connection unlocks whole-room automation, longer signal range, and the ability for the HUB to power and enable additional LINKS hardware across the facility.

"Run cultivation from a system that learns."
Every nutriLINK connects into Growlink OS, the cultivation management portal that turns your best irrigation practices into living Blueprints — standardised schedules and automation logic you can roll out across every room. Growlink OS includes Nova, Growlink's built-in AI, which compares performance across rooms, flags deviations from plan, and answers questions about crop performance without you having to dig through spreadsheets.
