文摘

Compared heat-expanded shale, crushed porcelain, and foamed glass as substrates. Evaluated substrate moisture content, plant growth, and chlorophyll fluorescence. Basil and stonecrop accumulated the most total biomass when grown in shale. Water retention could be improved with small particle sizes of porcelain. Use of porcelain could reduce embodied energy required to construct a green roof.
