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

Trigger Irrigation Zone by Zone Based on Actual Substrate Demand

Different zones, crop stages, and substrate types often call for different irrigation timing, and a single shared valve schedule rarely fits all of them well. The Growlink ValveLINK 8-Channel Irrigation Controller drives up to eight independent valves, each configurable with its own manual, scheduled, or sensor-based logic, so zones can water on genuinely different strategies from one controller.

Each channel supports up to 1A, with 2.7A combined across all eight, and the controller pairs with TerraLINK substrate moisture data so irrigation events can fire automatically once moisture drops to a set threshold rather than running on a fixed clock alone.

Key Features & Benefits

• 8 Independent Irrigation Channels: Runs different watering strategies across zones, stages, or substrate types.
• 1A Per Output, 2.7A Combined: Supports a wide range of standard irrigation solenoid valves.
• Three Control Modes: Manual, scheduled, and sensor-based operation fit each zone's own strategy.
• Substrate-Data-Driven Irrigation: Pairs with TerraLINK moisture readings to trigger events based on real demand.
• Zone-Level Precision: Different seedling, vegetative, and flowering zones can each run their own program.

Who Should Use This

Multi-zone growers who want irrigation timing to respond to actual substrate moisture and climate data, rather than a single fixed schedule across every zone, are the direct fit for ValveLINK, particularly operations running distinct crop stages side by side.

About Growlink

Since 2015, Growlink has built irrigation valve automation hardware under its LINKS brand, aiming to connect substrate sensor data directly to physical watering response through Growlink OS.

Frequently Asked Questions

How many valves can ValveLINK control?

ValveLINK controls up to eight irrigation valves independently, each with its own schedule, sensor trigger, or manual override. That independence lets different zones run entirely different watering strategies from a single controller.

Can substrate moisture data trigger ValveLINK irrigation events?

Yes, when both are connected to the Growlink platform, TerraLINK moisture readings can trigger ValveLINK irrigation events automatically once substrate moisture reaches a low threshold. This replaces a fixed schedule with irrigation timed to actual demand.

What valves are compatible with ValveLINK?

Standard irrigation solenoid valves rated up to 1A per channel are supported, with a combined 2.7A maximum across all eight channels. Confirm your valve specifications against these ratings before installation.

Does ValveLINK require a Growlink HUB?

Yes, a Growlink HUB or compatible LINKS infrastructure is needed to connect ValveLINK to Growlink OS for scheduling and sensor-based automation. Without that connection the controller loses remote scheduling and sensor-triggered response.
