Living green walls are constructed of panels that contain a variety of plants. These panels can be stacked horizontally or vertically to create a living green wall. Small-scale living green walls are suitable for residential spaces, while larger displays require custom-built construction. Each green wall is unique in terms of size, shape, and pattern, and can feature different plants with different colors and textures.
Plants in living green walls require water. While most green walls are self-watering, some require a watering system to keep the plants alive. It's also important to use a fertilizer to help the plants grow. The plants will die if the watering system is not in good working order.
Green Living Green Wall Planters have two primary purposes: they filter airborne particulate matter and convert CO2 into oxygen. One m2 of a living wall extracts about 2.3 kg of CO2 each year and produces 1.7 kg of oxygen. Furthermore, many studies have proven that plants can remove harmful VOCs from the air and convert them into compounds that plants use for food.
The idea of living green walls was invented by Stanley Hart White, a professor of landscape architecture at the University of Illinois from 1922 to 1959. His invention, however, did not progress much beyond prototypes in his backyard in Urbana, Illinois. In 1986, a French botanist specializing in tropical forests worked with architects Peter Rice and Adrien Fainsilber to create the first large-scale indoor green wall. Since then, there have been several notable green walls designed by Blanc.
