Green walls, also known as bio walls or living walls, are vertical gardens that are designed to grow plants on vertical surfaces, such as walls or fences. These innovative structures are composed of modular panels or containers filled with soil or other growing mediums, along with a network for irrigation and drainage. Green walls can be installed both indoors and outdoors, providing numerous benefits such as improving air quality, reducing noise pollution, and enhancing aesthetics. They offer a creative solution to maximize green space in urban environments and create visually stunning natural features that contribute to sustainability and well-being.
