DESCRIPTION
Granite is an intrusive igneous rock that forms from the slow solidification of magma beneath the earth's crust. This rock is mainly composed of 3 minerals: quartz (whose presence is between 20 and 60%), feldspar and mica.
In particular, in the cultivation of succulents it is an ideal component for plants which in nature grow on quartziferous substrates.
