Growlink LINKS ValveLINK 8-Channel Irrigation Controller — 2.7A Compatible with Growlink Copilot

Precision 8-Zone Irrigation Automation for Advanced Crop Steering with the Growlink ValveLINK

The Growlink™ LINKS ValveLINK 8-Channel Irrigation Controller delivers precise, automated irrigation management across up to eight independent zones, integrating seamlessly with Growlink's Copilot for advanced crop steering programs. Each of the eight channels controls an individual irrigation valve independently — enabling tailored watering schedules, shot volumes, and timing strategies for different crop zones, growth stages, or substrate types within the same facility.

Supporting up to 1 amp per output (2.7A max combined), the ValveLINK operates across three control modes — manual, scheduled, and sensor-based — giving cultivators the flexibility to match irrigation automation to their specific crop steering philosophy. Its rugged, durable construction ensures reliable performance in demanding agricultural environments, and its integration with Growlink OS and Copilot enables coordinated irrigation responses driven by real-time substrate moisture, climate, and plant demand data. Made in the USA.

Key Features & Benefits

• 8 independent irrigation channels — control up to eight valve zones individually for zone-specific watering programs across different crops, stages, or substrate types.
• Growlink Copilot compatible — integrates with Growlink's advanced automation engine for sensor-responsive crop steering programs beyond basic scheduling.
• Three control modes — manual, scheduled, and sensor-based operation provide flexibility to implement any irrigation strategy from simple schedules to fully automated moisture-driven programs.
• 1A per output / 2.7A combined — supports a wide range of standard irrigation solenoid valves across all eight channels simultaneously.
• Zone-level precision — independent channel control enables different irrigation strategies for seedling, vegetative, and flowering zones within the same facility.
• Rugged, durable construction — engineered for reliable long-term performance in high-humidity cultivation environments.
• Made in the USA — built to commercial agricultural standards for professional-grade reliability.

Who Should Use the Growlink ValveLINK

The ValveLINK is the essential irrigation controller for commercial indoor cultivators running multi-zone irrigation systems who need precise, automated valve control integrated with Growlink's automation platform. It is particularly valuable for operations implementing data-driven crop steering strategies where irrigation timing, frequency, and volume are dynamically adjusted based on substrate moisture data from TerraLINK sensors or climate conditions from ClimaLINK sensors through Growlink Copilot.

Sensor-Driven Irrigation for Precision Crop Steering

Advanced crop steering in indoor cultivation hinges on the ability to deliver the right amount of water at precisely the right time — not according to a fixed clock, but in response to actual plant and substrate conditions. The ValveLINK's sensor-based control mode, combined with Growlink Copilot, enables irrigation events to be triggered automatically by TerraLINK substrate moisture readings, VPD targets, or custom automation rules. This closes the loop between environmental sensing and irrigation delivery, creating a truly responsive system that adapts to plant demand throughout every growth phase.

Frequently Asked Questions

How many irrigation valves can the ValveLINK control?

The ValveLINK controls up to eight irrigation valves independently across eight channels. Each channel can be programmed with its own schedule, sensor trigger, or manual override.

What is Growlink Copilot and why does it matter for irrigation?

Growlink Copilot is Growlink's advanced automation engine that enables sensor-responsive, rule-based automation programs. When the ValveLINK is integrated with Copilot, irrigation can be triggered and adjusted dynamically based on real-time substrate moisture, VPD, temperature, or other sensor inputs — enabling true data-driven crop steering rather than fixed schedules.

Can TerraLINK substrate moisture data trigger ValveLINK irrigation events?

Yes. When both are connected to the Growlink platform, TerraLINK moisture readings can be used by Growlink Copilot to trigger ValveLINK irrigation events automatically when substrate moisture falls to a low threshold, enabling demand-driven irrigation automation.

What type of irrigation valves are compatible with the ValveLINK?

The ValveLINK supports standard irrigation solenoid valves up to 1A per channel (2.7A combined across all channels). Verify valve specifications against channel ratings before installation.

Does the ValveLINK require a Growlink HUB?

The ValveLINK integrates with the Growlink LINKS platform. A Growlink HUB or compatible LINKS infrastructure is required to connect the controller to Growlink OS for scheduling, Copilot automation, and remote management.
