Grodan 75x75x65mm Rockwool Cube No Hole

Description

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.
