Growlink LINKS HUB Communication Hub Controller — 8-Port 24VDC Ethernet or WiFi

The Central Command for Your Growlink LINKS Automation Network

The Growlink™ LINKS HUB is the backbone of any LINKS-based cultivation automation system, serving as the central communication point that connects, coordinates, and manages all LINKS devices through a single unified interface. With 8 ports and dual-mode connectivity via Ethernet or Wi-Fi, the HUB integrates sensors, controllers, and automation modules into the Growlink platform for comprehensive, real-time environmental management across your entire grow operation.

Operating on 24VDC at up to 1A, the LINKS HUB is engineered for simplicity and scalability — equally suited to compact single-room grows and large multi-zone commercial facilities. Whether deployed as a standalone controller or as part of a larger Growlink infrastructure, it provides the flexible integration needed to centralize monitoring, automate responses, and manage cultivation environments with precision. Made in the USA.

Key Features & Benefits

• 8-port connectivity — supports up to 8 simultaneous LINKS device connections for comprehensive automation coverage across a single grow zone or room.
• Ethernet and Wi-Fi support — flexible dual-mode connectivity accommodates wired and wireless infrastructure for diverse facility layouts.
• 24VDC / 1A operation — reliable, low-voltage power delivery engineered for continuous operation in cultivation environments.
• Universal LINKS compatibility — integrates the full ecosystem of Growlink LINKS modules including ClimaLINK, TerraLINK, LightLINK, RelayLINK, QuadLINK, and more.
• Centralized Growlink OS management — all connected device data and controls are consolidated in the Growlink platform for unified monitoring, automation, and analytics.
• Scalable architecture — additional HUBs can be deployed across rooms or zones, each managed within the same Growlink OS instance for facility-wide oversight.
• Made in the USA — built to professional cultivation standards for long-term reliability in demanding indoor and greenhouse environments.

Who Should Use the Growlink LINKS HUB

The LINKS HUB is a foundational component for any grower building out a Growlink LINKS automation system. It is essential for operations deploying multiple LINKS sensors or controllers that need to communicate with the Growlink platform, and is particularly valuable in commercial facilities where centralized, remote management of environmental controls across multiple zones is required.

Building a Scalable Cultivation Automation Infrastructure

The LINKS HUB is designed to grow with your operation. Starting with a single HUB for one room, cultivators can expand to additional HUBs as new zones are developed — all managed through the same Growlink OS interface. This modular approach eliminates the need to overhaul infrastructure as facilities scale, making the LINKS HUB a long-term investment in automation capability rather than a fixed-capacity solution.

Frequently Asked Questions

How many LINKS devices can connect to one HUB?

The LINKS HUB has 8 ports, supporting up to 8 simultaneous LINKS device connections. For operations requiring more connections in a single space, multiple HUBs can be deployed and managed within the same Growlink OS environment.

Does the HUB require a wired Ethernet connection?

No. The LINKS HUB supports both Ethernet and Wi-Fi connectivity, giving you flexibility to use wired or wireless infrastructure depending on your facility layout and preference.

Which Growlink LINKS devices are compatible with the HUB?

The LINKS HUB is compatible with the full range of Growlink LINKS modules, including ClimaLINK, CanopyLINK, TerraLINK, LightLINK, RelayLINK, QuadLINK, HVACLINK, ValveLINK, and TankLINK systems.

Can I manage multiple HUBs from a single Growlink account?

Yes. Multiple LINKS HUBs across different rooms or zones can be connected to the same Growlink OS account, providing a centralized dashboard for monitoring and managing your entire facility.

Is the HUB suitable for use in high-humidity grow environments?

Yes. The LINKS HUB is designed for deployment in cultivation environments and built to perform reliably under the humidity and temperature conditions typical of indoor growing facilities.
