This mineral plant substrate gives plants an optimal air-water ratio, a stable pH value and acts as a reservoir for water, nutrients and fertiliser, which it gives back to the plants individually and as required.
With the excellent drainage capacity of this substrate, waterlogging is not an issue. It consists of high-quality pumice, zeolites & light lava and remains structurally stable because, compared to earth/soil, the substrate can neither compact nor clump.
Due to its purely mineral basis, the substrate does not offer any surfaces for fungi or pests and is therefore ideal for allergy sufferers.
