Cultiwool Blocks have an optimum air/water ratio for healthy root growth and allow for great continued rooting thanks to the extremely even distribution of water and EC. These blocks have an excellent water absorption and (re)saturation rate and feature the exclusive Plant Comfort fibre structure which has a lower density of resistance during rooting with no loss of firmness. With Cultiwool Blocks you expect the highest quality, consistent stone wool. The quick and easy uptake of water and the homogeneous distribution of water throughout the substrate are one of the most important features of a growing medium.
