{"product_id":"growlink-quadlink-controller","title":"Growlink quadLINK Controller","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: GL-LINK-QUAD\u003cbr\u003e\n• Controlled Outlets: 4 × independently switched outlets\u003cbr\u003e\n• Receptacle Type: NEMA 5-15R\u003cbr\u003e\n• Voltage: 120VAC per outlet\u003cbr\u003e\n• Current Rating: 6A maximum per outlet\u003cbr\u003e\n• Combined Maximum Load: 9A across all four outlets\u003cbr\u003e\n• Relay Durability: 100,000+ switching cycles\u003cbr\u003e\n• Relay Cycle Counter: Tracks up to 4 billion cycles per relay\u003cbr\u003e\n• Connectivity: Growlink LINKS HUB via RJ-45 or standalone secured 2.4 GHz Wi-Fi\u003cbr\u003e\n• 5 GHz Wi-Fi: Not supported\u003cbr\u003e\n• HUB Port Usage: 1 HUB port controls all 4 outlets\u003cbr\u003e\n• Control Modes: Manual, scheduled, and sensor-triggered\u003cbr\u003e\n• Independent Control: Each outlet can have its own schedule or automation trigger\u003cbr\u003e\n• Sensor Automation: Can respond to live Growlink sensor data such as VPD, temperature, humidity, CO₂, and substrate readings\u003cbr\u003e\n• Typical Applications: Irrigation pumps, CO₂ solenoids\/controllers, inline fans, circulation fans, supplemental lighting, dehumidifiers, and similar 120VAC loads\u003cbr\u003e\n• Remote Control: Growlink OS and Growlink mobile app\u003cbr\u003e\n• Run Logging: Supported through Growlink OS\u003cbr\u003e\n• Alerts: Supported through Growlink OS\u003cbr\u003e\n• Status Indicators: Individual LED for each receptacle + Wi-Fi status LED\u003cbr\u003e\n• Mounting: Wall mounting hardware included\u003cbr\u003e\n• DIN Rail: Optional DIN rail mounting kit available separately\u003cbr\u003e\n• Installation Environment: Indoor only\u003cbr\u003e\n• High-Humidity Installation: Sealed enclosure recommended where humidity exposure is unavoidable\u003cbr\u003e\n• 240VAC Equipment: Not designed for high-draw 240VAC equipment\u003cbr\u003e\n• HUB Requirement: Not required; standalone 2.4 GHz Wi-Fi operation is supported\u003cbr\u003e\n• Country of Origin: USA\u003c\/p\u003e\n\n\n\u003cp\u003eKey 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.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610195722276,"sku":"GL-LINK-QUAD","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/quadlink-controller-gl-link-quad.jpg?v=1791317785","url":"https:\/\/www.growitdepot.com\/products\/growlink-quadlink-controller","provider":"Grow It Depot","version":"1.0","type":"link"}
