Pumice Stone - 1000ml - 1-3mm size
Pumice is a type of pyroclastic rock. It is derived from lava which is replete with gas. Liquid lava is ejaculated in the air in the presence of explosive volcanic eruptions. While the lava plunges down the air, it causes the lava to cool down and consequently gases leak from the rock. In the end, the rock is left with full of holes generating the pumice’s two main characteristics which are lightness and porosity. A pumice stone can absorb water as much as it’s self-weight.
Pumice is an excellent soil conditioner, as it is highly porous, giving it excellent water and air holding properties. Advantages of using pumice in potting media and garden soils include:
—the porous nature of pumice allows it to hold vital nutrients in the microscopic surface pores, which helps regulate fertilizer feedings. It can even be supercharged with nutrients before it is added to the growing medium.
