Water need and water use efficiency of two plant species in soil-containing and soilless substrates under green roof conditions.

Despite the significance of urban landscapes, there are limiting factors like spaces and water resources to expand them across the world. These limitations necessitate the development of water-conserving strategies in vertical infrastructures such as green roofs. One water-conserving strategy is precise irrigation regimes based on the plant species' water needs.

Investigating the plant and air-quality performances of an internal green wall system under hydroponic conditions.

Internal green wall systems can be combined with building structures to bring positive impacts on people's quality of life in interior spaces. However, obtaining green wall systems to optimize the performances of these living walls still needs research works. This study was conducted to investigate the plant, and air-quality performance resulted from combining ornamental plants and growing media types in an internal green wall system.
