Pure expanded clay in 4–8 mm · 5 L for hydroculture, semi-hydro, drainage and potting-mix amendment. Its medium particle size and porous, stable granules balance airflow, even moisture movement and secure support around the roots.
Expanded clay is fired at high temperature to form a lightweight, porous and durable structure that neither rots nor compacts like an organic material.
A pure mineral material made from natural clay fired at high temperature, with no organic ingredients or built-in fertiliser.
The medium particle size supports water movement while keeping the root zone open.
The durable granules keep the plant upright without compacting over time.
The mineral material can be cleaned and reused when the granules remain in good condition.
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.
The medium size is a versatile option for hydroculture and semi-hydro because it combines support, capillary water movement and aeration.
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.
