Cultiwool Grow Blocks

The Cultiwool substrate blocks are provided with drain grooves at the bottom to improve the water-flow under the block. This is especially useful when the substrate blocks are placed on cultivation tables and concrete floors. Another benefit of the drain grooves under the block is that it will limit the contact surface with the ground. This will avoid bringing diseases into the plant via weak roots often in combination with too high temperatures.

The 6x6x4 and 6x6x6 Cultiwool Blocks come with a donut ring – a water chamber around the plug hole to place irrigation drippers. With the donut ring you will achieve an even more homogeneous distribution of the water.
