FAQs

What are these Cultiwool slabs best used for?+

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.

How many slabs come in one case?+

Each case contains 16 individually sealed Cultiwool Wide Slabs, ready for use in your hydroponic system.

What is the benefit of vertical fiber orientation?+

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.

Can I use these slabs for starting seeds or clones?+

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.

Are these slabs ready to use out of the box?+

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.

What makes Cultiwool a professional-grade choice?+

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.
