Cultiwool Rockwool 6x6x4 Block w/ Optidrain (64 pieces per case)

Cultiwool, formally known as Cultilene, has many years of experience developing Rockwool products in the Netherlands and is preferred by some of the largest industrial propagators in the world. The quality of their newest Rockwool cubes, plugs, and starter sheets allows superb air to water ratio and features a fibre structure that holds water longer and has less resistance for the roots to grow in, resulting in stronger roots. Cultiwool Rockwool also encourages faster initial rooting and its firmness is guaranteed. These blocks are designed for seedlings and cuttings.

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. 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.
