Grodan 75 x 75mm Rockwool Cubes – EU Ecolabel Certified

Grodan 75 x 75mm rockwool cubes are premium stone wool growing media developed for strong, uniform root development in hydroponic and professional horticulture systems. Manufactured by Grodan, part of the ROCKWOOL Group, these cubes deliver a stable air-to-water ratio that supports healthy plant establishment from propagation through early vegetative growth.

This certification, supported by annual independent audits, confirms Grodan as the only eco-labelled stone wool growing media available to professional horticultural growers, offering growers confidence in both performance and responsible production.
