Cultiwool 4" x 4" x 2.5" Block (216 Blocks/Case) - Cultilene

Cultiwools’ growing blocks are unique in the most efficient way. That
has everything to do with the consistency of our products. 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.


Not only can you expect the highest quality stone wool in the market,
but Cultiwool is also the first to introduce the ‘donut ring’ for the
retail market to even further improve water distribution. This is in
addition to the highly appreciated cross grooves to improve water flow
under the block, and the black/white foil to prevent algae growth.


The Cultiwool substrate blocks are provided with drain grooves at the
bottom to improve the waterflow 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 deseases in to the plant via weak roots often in combination
with too high temperatures.


As first in the industry, Cultiwool will provide the substrate with a
donut ring as well, a water chamber around the plug hole to place your
drippers. With the donut ring you will achieve an even more homogeneous
distribution of the water throughout the block. A welcome second
advantage is that you can not make any mistake anymore with the
positioning of the drippers in the block.
