Who This Is For
- You are upgrading your substrate volume because your plants are outgrowing their blocks before the final harvest cycle.
- You are switching to vertical fibre media because uneven water distribution is causing dry pockets in your root zone.
What We Found
- Vertical fibre orientation drains much more predictably than the cheaper horizontal slabs we used to carry.
- These 6 inch slabs give you more wiggle room for dripper placement compared to the standard 4 inch versions.
What Users Say
- Growers moving from blocks to these slabs say they stopped seeing transplant shock during the final stage.
- Users running large tables say their runoff is finally consistent because every slab holds the same water volume.

FAQs
These 36" x 6" slabs are specifically designed for the final stage of a plant's life cycle. They provide ample space for a mature root system to develop after transplanting from smaller starter media like Cultiwool 4x4 growing blocks.
Each case contains 16 individually sealed Cultiwool Wide Slabs, ready for use in your hydroponic system.
The vertical fiber structure promotes optimal water and nutrient distribution throughout the entire growing medium. This encourages roots to grow downwards, creating a stronger, healthier root system and preventing waterlogged zones.
While possible, it's not ideal. These slabs are quite large and designed for mature plants. We recommend starting seeds or clones in smaller, dedicated media like Cultiwool 1.5" cubes or plugs for better moisture control and higher success rates before transplanting.
Yes, they are sealed for sterility. However, like all stonewool products, it is essential to pre-soak and condition them to the correct pH level (typically 5.5 - 6.5) before introducing your plants.
All Cultiwool products are manufactured in Europe using high-quality stonewool with a focus on consistency. This homogeneity ensures that every slab performs predictably, which is critical for achieving reliable, repeatable results in a commercial cultivation environment.
