Granular clay of volcanic origin from Japan. It is a very porous substrate, its structure and granulometry allow the optimal aeration and the ideal moisture level retention for the proper development of plants. Since it’s in granulated form, it does not compact, it optimizes a good root development, and facilitates transplants.

Highly recommended for growing plants that need a lot of water, but without water logging, such as bonsais, and acidophilus plants that are found in unfavourable climates.
