Cultilene Rockwool also encourages faster initial rooting and its firmness is guaranteed. In addition, our Rockwool cubes feature Cultilene's unique PlantCOMFORT fiber structure. All blocks except the 3" x 3" x 3" have the unique Optidrain feature which allows for excess water to run off quicker, better aeration, less root damage, and more root growth stimulation.
