Growlink Precision Irrigation Controller

Product detailed description

Take absolute control of the nutrition and irrigation of your plants with the Growlink Precision Irrigation Controller. This professional device is the brain of the entire growing system, allowing you to fully automate and optimise the water and nutrient supply down to the smallest detail. Say goodbye to manual watering and dosing and welcome higher yields, healthier plants and significant savings in time and resources.

Key benefits for growers

With this controller, you will turn your growing into a precise and efficient process. Thanks to automation, you will save precious time that you would otherwise spend on daily routine tasks. By precisely controlling irrigation and nutrients, you will avoid mistakes such as overwatering or insufficient nutrition, which leads to higher quality and quantity of the harvest. The system also optimises water and fertiliser consumption, reducing your operating costs and making growing more sustainable.

Key features

• Independent control of 8 zones: The option to control up to 8 separate irrigation valves (24 VAC) for different groups of plants or growing systems.
• Precise nutrient dosing: Connection and control of up to 8 peristaltic pumps for automatic mixing of nutrient solutions according to your recipes.
• Advanced sensor integration: Support for substrate moisture, pH, EC and temperature sensors for data-driven control.
• Remote management via app: Full control and monitoring via a clear mobile app (iOS/Android) and cloud platform.
• Analysis and alerts: The system stores historical data, displays it in graphs and sends instant alerts when values deviate from the set parameters.

Intelligent control at your fingertips

The heart of the entire system is the cloud platform and Growlink mobile app. Wherever you are in the world, you have an immediate overview of all key parameters. In real time, you can monitor data from sensors, manually start irrigation cycles, adjust schedules or fine-tune nutrient solution recipes. All data is stored and visualised in clear graphs that help you analyse trends and further improve your growing strategy.

Flexible irrigation modes

The unit offers several control modes that adapt to any situation and the needs of your annual plants, whether you are growing tomatoes, chilli peppers or herbs. You can choose the most suitable way to provide them with moisture:

• On-Demand: Immediate start of irrigation with one click in the app.
• Cycle Timer: Setting repeated short cycles, ideal for hydroponic systems or rooting cuttings.
• Schedule: Classic irrigation scheduling for specific days of the week and exact times.
• Sensor Triggers: A fully automated mode where irrigation is triggered by a drop in substrate moisture below the level you set.

Easy installation and integration

Installation of the controller is quick and simple. The device is designed for mounting on a standard DIN rail, which allows for a clean and professional installation in a distribution board. Thanks to the Wi-Fi module, the unit easily connects to your network and is compatible with standard 24 VAC irrigation valves that are commonly available on the market.
