Product Description

3-5cm lava rock pumice for horticultural planting

Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface.

Volcanic rocks are light, porous and porous, with good permeability, and rich in a variety of trace elements. It is very suitable for the use of related soilless culture medium and potted plant material, and it can also be mixed with vermiculite, zeolite and perlite. It is a good plant material in horticultural planting.
