The Growlink LINKS 8-Port Device HUB (GL-LINK-HUB) is the required central controller for the Growlink LINKS ecosystem. It connects and powers up to eight LINK devices—including canopyLINK, valveLINK, lightLINK, hvacLINK, nutriLINK, batch tankLINK, relayLINK, and powerLINK—using standard RJ-45 cabling. Connected devices are managed through Growlink OS and the Growlink App, providing centralized monitoring, automation, scheduling, alerts, and historical data.

• Status Indicator: Connectivity status LED
• Country of Origin: USA
• Scaling: Additional HUBs can be deployed when more than eight device connections are required
• Sensor Expansion: A canopyLINK Sensor HUB can occupy one HUB port while connecting up to eight climate/substrate sensors
• Internet Requirement: Internet connection required for Growlink OS operation
• Installation Location: Recommended outside the grow environment or inside a sealed enclosure where humidity exceeds the operating limit.
Key Advantage: The LINKS HUB serves as the central communication and power backbone for an entire Growlink LINKS installation, combining eight individually buffered long-range device ports with Ethernet/Wi-Fi connectivity and centralized Growlink OS control. This makes it possible to build a modular climate, lighting, irrigation, nutrient, and HVAC automation system around a single network architecture.
