The living wall includes a built-in irrigation system. The supply of water to the wall is essential to healthy plant development. The back of each living wall module is kept moist to facilitate the natural composting of mature roots. Harvested rainwater from the building roof can be used for the wall.
Unlike some other living wall systems, the ANS Living Wall system does not rely on artificial fertilizers being pumped through the wall constantly. However, the irrigation system can be used to add a natural fertiliser or organic pesticides throughout the whole wall, if required.
The system reduces water wastage as it includes natural soil, thereby allows plants to absorb water and nutrients naturally rather than keeping them alive with a frequent flow of water and nutrients.
