Cultiwool X-Fibre Slabs are designed for growers who want fast, uniform plant development across the entire crop. Built using advanced rockwool fibre technology, they create a perfectly balanced root zone with consistent moisture, airflow, and nutrient availability.
Ideal for drip irrigation systems and larger plants, these slabs help you maintain full control over your grow — delivering strong roots, even growth, and high yields.
When growing in slabs, consistency is everything. Uneven moisture or oxygen levels can lead to irregular growth and reduced yields.
X-Fibre technology creates a controlled root environment, allowing water to distribute evenly while maintaining optimal air pockets. This results in stronger root systems and more uniform plant performance from start to finish.
The X-Fibre structure allows water to settle evenly through the slab while maintaining a balanced saturation level. Excess water drains away, while the slab retains enough moisture for consistent feeding.
This balance between water retention and oxygen availability is what drives rapid root development and stable growth.
Dial in your irrigation frequency early — consistent, small feeds throughout the day will maximise root development and help maintain perfectly balanced moisture levels in the slab.
