Living WallA living wall is a vertical garden. The plants grow in compartments on a porous vertical wall. The water is dripped down, and may feed moss and vines, other plants, some insects and bacteria. The water is captured at the bottom of the wall in a pool or pond to be recirculated to the top. The living wall is a form of urban agriculture or urban gardening. It may be built as a work of art for its beauty. It is sometimes built indoors to help cure sick building syndrome or otherwise increase the oxygen levels in recirculated air. It is also a means for water reuse, at least as utility water. The plants may purify a slightly polluted water (such as greywater), by using the dissolved nutrients. Bacteria may mineralise the organic components to make them available to the plants. Living walls are particularly suitable for cities, as they allow good use of available surface. They are also suitable in arid areas, as the circulating water is less likely to evaporate than in horizontal gardens. In arid and hot areas, the living wall can be part of the external walls of a building, and be used to refresh the latter. See also External links
