Awesome Water Retention

Cultiwool’s unique rockwool formula promotes a high percentage water retention for your rootzone. Which means that you have no fears that your plant’s will dry out.

Easy Irrigation System

Cultiwool has a unique formula that allows water to pool at the bottom of the slab whilst retaining a saturation level between 55 and 75%, if the water level gets too high the slab is formulated to release water to bring it back to the desired level. Similarly if there is too little water the system design allows you to easily re-soak the slab to improve saturation levels.
