quadLINK Controller

The quadLINK is a switching module that connects to your Growlink system via the HUB or Wi-Fi, letting you easily control up to four devices—including irrigation pumps, CO₂ systems, fans, and lights—through four independent NEMA 5-15R receptacles. Each outlet is independently switched and supports manual, scheduled, and sensor-triggered automation through Growlink OS.

Why the quadLINK

Four outlets. Total control.

Without intelligent outlet control, growers rely on manual timers and guesswork. The quadLINK brings four independently switched outlets into Growlink OS for precise, automated device management across your entire operation.

4 Independent NEMA 5-15R Outlets

Four independently switched receptacles, each rated at 6A with 9A combined maximum.

HUB or Wi-Fi Connectivity

Connect via the HUB connection port or directly over Wi-Fi for flexible deployment.

Versatile Device Control

Control irrigation pumps, CO₂ systems, fans, lights, and other 120VAC equipment.

Growlink App Integration

Remote monitoring, firmware updates, automation rules, alerts, and real-time data through the Growlink mobile app.

LED Status Indicators

Wi-Fi status LED and per-receptacle LED indicators show power and connection status at a glance.

100,000-Cycle Relays

Industrial-grade relays rated for 100,000 cycles with counters tracking up to 4 billion cycles per relay.

The Growlink LINKS System

One HUB. Complete room control.

The quadLINK connects to your LINKS HUB — integrating outlet control with climate, lighting, irrigation, and sensor devices into a single automated system managed through Growlink OS.
