The Growlink valveLINK is an 8-channel 24VAC irrigation valve controller designed for multi-zone commercial cultivation. Each channel operates independently, allowing different irrigation schedules or control logic for separate rooms, benches, trays, or crop stages. It can operate manually or on scheduled timers, while integration with Growlink Copilot and TerraLINK substrate sensors enables irrigation events to respond to live substrate VWC and EC data.
• SKU: GL-LINK-VALVE
• Valve Channels: 8 independent outputs
• Valve Voltage: 24VAC, simulated using 50% PWM at 1 kHz
• Valve Opening: 1-second DC inrush pulse
• Output Current: 1A per channel; 2.7A maximum combined
• Input Power: 24VDC, 2.7A
• Power Adapter: Included
• Compatible Valves: Standard 24VAC 2-wire diaphragm valves and 24VAC motorized ball valves
• Control Modes: Manual, scheduled, and sensor-based
• Manual Mode: Fire individual valves on demand through Growlink OS
• Scheduled Mode: Independent time-based irrigation programs for each channel
• Sensor-Based Control: Uses live substrate VWC and EC data through Growlink Copilot
• Copilot: Analyzes previous irrigation cycles and suggests adjustments for subsequent events
• AutoPilot: Automatically implements Copilot recommendations for autonomous crop steering
• Connectivity: Wi-Fi or wired RJ-45 through the LINKS HUB
• Software Integration: Growlink OS and Growlink Copilot
• Event Logging: Irrigation events are logged and time-stamped in Growlink OS
• Independent Scheduling: Each of the 8 channels can have its own schedule, trigger logic, shot volume, and sensor pairing
• LINKS Ecosystem: Works alongside LINKS HUB, TerraLINK substrate sensors, canopyLINK, and climaLINK devices
• System Expansion: Additional valveLINK controllers can be added for larger facilities
• Installation: Recommended outside the grow environment; use a sealed enclosure if installed in a high-humidity area
• Origin: Made in USA
Key Advantage: The valveLINK combines 8 independent irrigation zones with sensor-driven crop steering, allowing irrigation to move beyond fixed timers. With Growlink Copilot/AutoPilot and TerraLINK substrate data, each valve zone can respond to actual substrate conditions and automatically adjust irrigation timing and strategy.
