8-channel canopy sensor hub — substrate, climate, and light data unified in Growlink OS.
Growlink canopyLINK consolidates up to eight SDI-12-compatible sensors into a single device, feeding real-time substrate, climate, and light data into Growlink OS for automated, data-driven crop management. Connects via wired RJ-45 or 2.4 GHz Wi-Fi — no manual sensor addressing required.
The Growlink canopyLINK is an 8-port sensor aggregation hub built for the Growlink LINKS ecosystem. It accepts up to eight SDI-12 compatible sensors — one per M8 port — and transmits all readings to Growlink OS as a single registered device. That matters at scale: instead of burning individual Hub ports on every sensor in a room, you consolidate an entire zone's sensor network through one canopyLINK, keeping your Hub ports available for other LINKS modules.
Compatible sensors include the Climalink climate sensor, Terralink and Terralink+ substrate sensors, Acclima TDR, ESM3, and TEROS 12 (some require an M8 adapter cable). Automatic sensor addressing means the hub detects and registers connected sensors on its own — no manual configuration per channel. The canopyLINK is designed and manufactured in the USA for commercial cultivation environments.
The canopyLINK fits any licensed cannabis or hemp operation running Growlink OS that needs dense, reliable sensor coverage across grow zones. Single-room craft builds can use it to monitor substrate moisture, EC, and temperature across multiple container sites from one device. Multi-room commercial facilities benefit most: deploy one canopyLINK per zone, mix substrate and climate sensors per the room's needs, and surface all data in a single Growlink OS dashboard.
It's also the right tool for operators building out crop steering programs. Accurate, canopy-level VWC, EC, temperature, RH, VPD, and light readings are the inputs that make irrigation triggering and climate automation precise. If you're manually pulling data or working off room-average readings, the canopyLINK is the hardware layer that closes that gap.
The canopyLINK connects upstream to the Growlink ecosystem via your choice of wired RJ-45 (HUB Connection Port) or 2.4 GHz Wi-Fi. Wired is recommended for facilities where reliability is non-negotiable or where additional LINKS hardware requiring a HUB connection is already in use. Wi-Fi works well for standalone monitoring setups and situations where running cable is impractical.
Power input is 24 V DC via the included AC/DC adapter. The unit ships with a mounting kit and a 10 ft RJ-45 cable. Installation best practice per Growlink is to mount above the plant canopy and bench level to protect the M8 connectors and board from moisture — avoid positioning below misters, foggers, or humidifiers, and locate away from condensation zones. Sensor cables can be extended using Growlink's M8 extension cables where reach is a factor.
Once registered, the canopyLINK surfaces all connected sensor data in Growlink OS — the same platform managing lighting, climate, irrigation, and nutrient control in a LINKS-equipped facility. From there, operators can configure automation rules triggered by actual canopy readings: irrigation events based on live VWC and EC, climate adjustments off real-time VPD, or alerts when any parameter drifts out of spec.
Remote monitoring, firmware updates, and analytics are all handled through the Growlink app without requiring physical access to the device. For facilities running Growlink's AI-driven Copilot or building toward full environmental automation, the canopyLINK is the sensor aggregation layer that makes the data inputs actionable. It registers as a single device in Growlink OS regardless of how many sensors are connected, keeping facility dashboards clean as installs scale.

No. The canopyLINK can connect directly to the Growlink platform over 2.4 GHz Wi-Fi without a HUB. A HUB is recommended if you want a wired, more fault-tolerant upstream connection or if you plan to add other LINKS modules that require a wired HUB connection.
Yes. The eight M8 ports accept any supported SDI-12 sensor — Climalink, Terralink, Terralink+, Acclima TDR, ESM3, TEROS 12 — in any combination across the available channels, up to eight total.
Not without an adapter. Older Terralink cables use a different connector. Current Terralink sensors for the LINKS system ship with an M8 connector and plug directly into the canopyLINK's M8 ports. Growlink offers M8 adapter cables for legacy sensors.
It registers as a single device regardless of how many sensors are attached. This keeps your device list manageable and frees up Hub ports for other LINKS hardware as your facility scales.
Depending on which sensors are connected: volumetric water content (VWC), substrate EC, substrate temperature, air temperature, relative humidity (RH), vapor pressure deficit (VPD), CO2, and light intensity — with additional parameters depending on the specific sensor models deployed.
