Cultiene 4" x 4" x 4" Block Rockwool Cubes Stonewool with Hole, with Optidrain Hydroponics Grow Media
Cultilene 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.
