Expanded Clay Pebbles

Expanded Clay for Water treatment: Waste water---Biofilter, Filtrations

For home wastewater treatment, Leca/Expanded clay aggregate can replace distance gravel in aerobatics filter manufacturing.

And also in anaerobic filters, the porous of Leca/Expanded Clay aggregate is a suitable environment for growth of useful bacteries.

Expanded Clay Packing & Shipping

Expanded clay pellets, also known as LECA (lightweight expanded clay aggregate), are formed from small round balls of clay which are heat treated, causing them to expand and become porous and are among the most popular grow media today. They are completely sterile and inert with a neutral pH. They can be sterilized, flushed and re-used and provide good root support, great drainage and aeration.

2. Why choose Expanded Clay ?

Hydro Clay Pebbles are the most ecologically and economically sustainable choice for your growing needs!  

• Manufactured on the basis of clay and processed into baked clay pellets (8-16 mm)

• Light and porous appearance due to a special manufacturing process

• Supports drainage and aeration

• Loosens the soil and provides a long-lasting water, thermal and air circulation

• Indispensable additive to your soil for repotting 

3. How can we made Expanded Clay ?

The clay is formed into pellets and then fired in rotary kilns at 1200°C, which causes it to expand inside, like popcorn, and become porous. The pellets drain freely and don’t hold excess water, providing good oxygen levels around the root area. This growing medium called LECA (Light Expanded Clay Aggregate) also provides the necessary support for the plant along with its ability to absorb the correct amount of water and oxygen. Healthy and beautiful plants are guaranteed with this optimal ratio of water and oxygen.
