Using domestic peat, coir dust, perlite, ceramisite as the component materials in the substrate formulation, the physico-chemical characteristics of the different substrate formulations were measured. Two substrate formulations were suitable for lightweight roof greening according to their physical and chemical characteristics. The effects of two substrate formulations on the growth of experimental Sedum plants were studied. The results showed that S. nicaeense was not significantly different in two substrate formulations. Other four Sedum plants grew strongly in the F3 substrate formulation, and biomass was significantly accumulated. The substrate formulation F3 that the ratio was domestic peat (2 portions), coir dust (3 portions) and perlite (1 portion) was fit for Sedum plants in lightweight roof greening.
