Growlink Precision Irrigation Controller

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

Key benefits for growers

With this controller, you turn your growing into a precise and efficient process. Thanks to automation , you save valuable time that would otherwise be spent on daily routines. By precisely controlling irrigation and nutrients, you avoid mistakes such as overwatering or under-nutrition, leading to an increase in the quality and quantity of your harvest. In addition, the system optimises water and fertiliser consumption, reducing your operating costs and making growing more sustainable.

Key features

• Independent control of 8 zones: the ability to control up to 8 separate irrigation valves (24 VAC) for different plant groups or growing systems.
• Precise nutrient dosing: Connect and control up to 8 peristaltic pumps to automatically mix nutrient solutions according to your recipes.
• Advanced sensor integration: support for substrate moisture, pH, EC and temperature sensors for real data-based 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 deviations from setpoints occur.

Intelligent control at your fingertips

The heart of the system is the cloud platform and the Growlink mobile app. Wherever you are in the world, you have an instant overview of all key parameters. You can monitor sensor data in real time, manually trigger irrigation cycles, adjust schedules or fine-tune nutrient solution recipes. All data is stored and visualised in clear graphs to help you analyse trends and further refine your growing strategy.

Flexible irrigation schedules

The unit offers several control modes to adapt to any situation and the needs of your annuals, whether you are growing tomatoes, chillies or herbs. You can choose the most appropriate way to give them moisture:

• On-Demand: instantly start irrigation with one click in the app.
• Cycle Timer: Set 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.
