Grodan Rockwool Cubes

Grodan Rockwool cubes are made of 100% basalt rock and are manufactured in Holland. We use only the highest of quality growing mediums.

GENUINE GRODAN ROCKWOOL cubes.
Completely sterile and inert – ideal hydroponic growing medium. Reduced risk of pests and disease.

Even root growth – predominantly vertical fibre structure means identical levels of resistance for each root, so roots grow evenly.

Increased root development – structure of the rockwool is designed for optimum air / water balance and accelerated rooting.

Uniformity – quality and structure is uniform, so water content and EC (CF) will remain the same for every plant.

Re-wetting – Grodan rockwool is easy to re-saturate if it dries out, reducing the risk of root damage.
