Growlink LINKS nutriLINK 8-Output Nutrient Delivery Controller

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. Technical Specifications Outputs 8 universal dosing pump outputs Sensor Inputs pH, EC, and flow Dosing Programs Fully customisable per crop stage Monitoring Real-time dosing & sensor data logging Connectivity HUB port (wired) or 2.4GHz Wi-Fi (standalone) Platform Integration Growlink OS & Copilot 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.
