The Growlink quadLINK (GL-LINK-QUAD) is a four-channel relay switching module that brings four independently controlled 120VAC outlets into the Growlink OS environment. Each outlet can operate independently using manual control, time-based scheduling, or sensor-triggered automation, making the unit suitable for controlling pumps, CO₂ equipment, fans, supplemental lighting, dehumidifiers, and other 120VAC ancillary equipment. It can connect through a Growlink LINKS HUB or operate as a standalone device over secured 2.4 GHz Wi-Fi.

Key Advantage: The quadLINK turns one Growlink HUB port into four independently programmable 120VAC outputs, allowing each connected device to respond to its own schedule or live sensor conditions. This provides a compact way to automate multiple ancillary devices while keeping their control and monitoring centralized in Growlink OS.
