Growlink is a Denver-based cultivation-technology company delivering scalable automation that adapts to your environment, your data, and your goals. Their platform unifies climate control, precision irrigation, nutrient delivery, and crop steering under a single connected system — Growlink OS — with an AI assistant, Copilot, that analyzes sensor data and suggests daily adjustments for consistent, high-quality yields.
The lineup scales with the operation: the enterprise CORE control panel and CONNECT room controller for commercial facilities, the NDS and NDK fertigation systems for automated nutrient delivery, and the LINKS IoT ecosystem — affordable, Wi-Fi and hub-connected devices that let craft and small commercial growers start small and scale big. Every tier runs on the same software and integrates with the gear you already own through the Integration Hub.
A 15.6″ touchscreen on the wall of every room. VPD, temperature, humidity, CO₂ and leaf VPD live against setpoints, with 24-hour trend lines and irrigation history on one screen — substrate moisture, root-zone EC, shot history and dryback percentage included. An LED ring around the bezel reads the room from down the hallway: green on target, amber drifting, red action needed, purple when Nova AI has something to say. No login. No laptop.
Every grow is unique, but success starts with control, consistency, and clarity. Growlink scales from a single room to a multi-state footprint — find your tier and the equipment that fits.
Personal and medicinal growers automating one room’s worth of equipment with pro-grade precision.

View full specsOur CORE and CONNECT lines are designed for mid- to large-scale commercial projects where every facility is unique. Because CORE systems are custom-built, UL-listed control panels, those opportunities typically require a facility floor plan, equipment list, or completed mechanical, electrical, and plumbing (MEP) plans before we can properly scope the project.

IoT-enabled monitoring and control devices that connect over Wi-Fi or through the LINKS Device HUB. Mix and match to automate irrigation, nutrient delivery, climate, lighting, and monitoring — then grow into full commercial control on the same platform.

Connects all your LINKS devices for control from anywhere.

Automates irrigation valves for exact per-zone watering.

Monitors & controls nutrient mixing tanks for consistent recipes.

Relay control for HVAC, humidifiers & mixed-voltage gear.

Four-outlet smart power with individual scheduling.

Connects climate & substrate sensors for accurate control.

Control lighting intensity, spectrum & timing.

Run up to four lighting channels from one device.

Aspirated temp, humidity, VPD, light & optional CO₂.

Substrate VWC%, EC & root-zone temp for crop steering.

PPFD, DLI, lux, color temp & flicker for canopy mapping.
The LINKS family also includes hvacLINK (smart day/night thermostat) and powerLINK (120VAC 15-amp device control). Ask us to spec a complete LINKS package for your room.
One brain for the entire facility. Growlink OS automates climate, irrigation, and nutrient delivery from a single platform — with real-time dashboards, historical trends, and intelligent alerts.
Proven scheduling templates you customize for consistency each cycle.
AI crop steering that suggests precise daily adjustments from your data.
Automates climate, irrigation & nutrients from one platform.
Live data, setpoints, dashboards & alerts from anywhere.
Bring your existing controllers, sensors, and devices into the Growlink ecosystem. The Integration Hub lets you keep the hardware you already trust while unlocking the automation, monitoring, and intelligence of Growlink OS — running Blueprints and Copilot on your current setup with no rip-and-replace.
Growlink plays nicely with the brands you already run — from lights and HVAC to sensors and fertigation controls — connecting Fluence lighting, Quest dehumidifiers, Priva irrigation, and more into one intuitive platform.
Integration Hub detailsMatrix® is a natively supported protocol on the Growlink digital lightLINK. Your Matrix fixtures take intensity and spectrum commands directly from Growlink OS — the same platform already running your climate and irrigation now drives the light recipe, including far-red and UV. No separate lighting controller to program, and no rip-and-replace.
The digital lightLINK is a communication bridge that sits between the LINKS Hub and your fixtures, translating LINKS commands into the fixture's own control language over RS-485. One module is required per lighting zone.

Matrix fixtures use a circular three-pin connector for digital data. The RJ-12 port on the digital lightLINK is reserved for ThinkGrow and DLI fixtures — Matrix wires to the screw terminal block instead. Cut and strip one end of the Matrix data cable and land the three conductors as shown.
The terminal blocks are pluggable — pull the block off the module face to wire it on the bench, then plug it back in. Same trick makes module swaps painless later.
Add and register devices one at a time so each gets addressed cleanly.
Mount outside the growing area where you can reach it for service, away from misters, foggers, and condensation. Indoor, dry locations only — use a sealed enclosure above 70% continuous RH, and orient the power connection downward.
Each module bridges one zone, so a four-room flower building needs four. The digital lightLINK also requires a canopyLINK with a Climalink sensor on the same Hub for full operation — that's what feeds the canopy temperature behind high-heat dimming and shutdown, alongside sunrise/sunset ramping and adaptive light intensity. Tell us your room count and fixture models and we'll spec the whole package. Get a lighting-control quote →
Running 0-10V instead? Matrix fixtures also accept standard 0-10V analog dimming, which the 4-Channel lightLINK drives. Analog gets you per-channel dimming; the digital lightLINK's RS-485 path is what unlocks true spectrum, far-red, and UV control from Growlink OS — so it's the one we spec for Dyna and Hybrid rooms.
