|Rockwool Cultilene Wrapped Cube substrate is a genuine natural product made from volcanic rock, or basalt.|
Using the latest technologies, the basalt is heated and spun in several directions. This gives it its unique fibre structure. This special X-fibre structure is characterised by fibres that run in all directions. One advantage of this structure is it facilitates better root distribution throughout the entire slab, as does natural soil. It also encourages the growth of more hair roots in the top part of the slab, which allows the plants to absorb more nutrients.
