Pure, coarse expanded clay in 8–16 mm · 5 L for hydroculture, semi-hydro and drainage layers. The durable, porous granules create larger air spaces, move excess water away quickly and provide stable support for plants with stronger root systems.
The coarse particles leave generous spaces between the granules. Water can move away freely while air circulates through the root zone.
A pure mineral material made from natural clay fired at high temperature, with no organic ingredients or built-in fertiliser.
The larger granules allow excess water to move away instead of pooling around the roots.
Open spaces support air exchange throughout the root zone.
The stable mineral structure suits larger plants and roots that need room to develop.
Transport dust is normal with a granular mineral product. A quick rinse or wetting helps remove it before planting.
Use clean water to bind and remove fine transport dust.
Use it alone in a hydroculture system or as a mineral drainage component.
Arrange the roots and add the granules gradually so the air spaces remain open.
Follow the plant's needs, the water-level indicator and the fertiliser instructions for your system.
The material contains no built-in nutrients. In hydroculture or semi-hydro, use a suitable fertiliser and follow that product's dosage instructions rather than applying an improvised ratio.
The 5 L pack is practical for focused repotting jobs and smaller setups.
Rinsing does not change the material; it simply removes fine dust that can form during transport.
Keep the pack closed in a clean, dry place. After reuse, clean the granules and allow them to dry completely.
Expanded clay is a natural mineral product. Minor differences in colour, surface or shape between batches are expected.
Two useful categories for matching the growing medium and nutrition to your own hydroculture setup.
Choose a water-soluble fertiliser suitable for soil-free growing and follow the product's dosage instructions.

It is pure expanded clay made from natural clay fired at high temperature. This is a stable, porous mineral material with no organic ingredients or built-in fertiliser.
Choose the coarse size when you want larger air spaces, rapid drainage and room for a stronger root system.
A quick rinse or wetting with clean water is recommended to remove fine dust that can be produced during transport.
No. For hydroculture, add a suitable fertiliser separately and follow the dosage and schedule for that specific product.
Yes, provided the granules remain in good condition. Remove roots and residues, clean them carefully and allow them to dry before using them again.
Yes. As the raw material is natural clay, minor differences in colour, surface and shape between batches are normal.
