creating refreshing and natural environments in limited spaces without cluttering or occupying additional floor area. With a green wall, you can enjoy a lively, vibrant, and eco-friendly atmosphere anywhere.
How to Irrigate a Green Wall
One of the main challenges in maintaining a green wall is its irrigation system. Since watering multiple plants manually at high elevations is impractical, automated irrigation systems are used to supply water efficiently and consistently. These systems distribute water evenly and allow for recycling and reuse of excess water.
In general, two main irrigation systems are used for green walls:
- Hydroponic irrigation systems
- Drip irrigation systems
These systems prevent water waste and ensure proper hydration. Modern drip technology has been optimized for automated and smart irrigation systems, making it highly suitable for interior and exterior green wall designs.
Key Components of a Green Wall Irrigation System
Water Pump
Water pressure depends on the height of the green wall. For tall walls, high-pressure pumps are required. In some cases, city water pressure may be sufficient (about 2 bars), eliminating the need for a pump.
Pipes and Connectors
polyethylene spaghetti pipes (6–8 mm) are used to connect each pot and deliver water directly to the root zone.
Nozzles & Drippers
Adjustable drippers are recommended due to different water needs among plant species. They allow you to control the water flow for each pot and ensure precise irrigation.
Automatic Irrigation Control
Since green wall plants grow in a limited soil environment, irrigation must be accurate and gentle to prevent root damage and excess drainage. Automatic timers and irrigation controllers allow precise daily watering (1–5 minutes), ensuring consistent care.
Water Source
- Best option: Well water (with filtration)
- Alternative: Municipal tap water (commonly used in residential buildings)
Important Tips for Green Wall Irrigation
- Choose the right water source
- Use filtration to avoid sediment and system damage
- Ensure water pressure reaches all sections of the wall
- Use waterproof and corrosion-resistant materials
- Test the irrigation system before full operation
By following these principles, you can maintain a lush, healthy, and long-lasting green wall full of natural energy and life
