Grodan Rockwool AO36 6/15 Cubes (10)

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

  • 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.
