Feature of our expanded clay.
- Ultra-lightweight
- Ph Neutral
- Poisonless & Tasteless
- Round Pebbles
The round pebbles do not compress or touch. The uniform space between the pebbles provides even aeration and wetting throughout, allowing roots to fully grow into the medium. The clay surface repels water, but surface tension coats each clay ball in a thin coat of water, perfect conditions for roots. Cracked rocks absorb water like a sponge.
- Porous Structure
It is made of clay with high water storage properties and balanced capillary action to accelerate plant growth.
large pore volumes and surface areas -
make it an ideal media for biological treatment.
excellent for treating raw water containing ammonia,
Manganese, iron etc
Expanded clay can be used for a number of different water and waste water treatment applications


Environmentally friendly and reusable.
Ensures good root aeration,
Enhances microbial action in aquaponics,
prevents rotting, prevents excess acidity and prevents soil pests.
Our Expanded pebbles also offer high water storage properties and balanced capillary action.
