The Cultilene Blocks allow for great continued rooting thanks to the extremely even distribution of water and EC. With an optimum air/water ratio for healthy root growth, these blocks have an excellent water absorption and (re)saturation rate. They feature the exclusive Plant Comfort fibre structure with a lower density of resistance during rooting and no loss of firmness. All blocks except the 3x3x3 also have the Optiplus feature, which is a unique design on the underside of the block allowing for excess water to drain away easily.
