Specification

Expanded clay are made from 100% natural clay. They are clean, pH stable, and offer great aeration and drainage in hydroponics, especially in flood and drain, deep water culture, and drip feed systems. Due to their unique structure and ability to cover a large surface area, they offer the ideal environment to foster beneficial bacterial growth around the root zone, leading to naturally healthier plants.

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.

Application of our expanded clay.

Expended Clay (LECA) main use is as a hydroponic/aquaponics growing media in flood and drain and dripper hydroponics/aquaponics systems.

Expanded Clay Balls/ pebbles can also be mixed with other hydroponic growing media like Perlite, Coco or Soil to give better aeration.

To create better drainage when growing in pots add a layer of Clay pebbles in the bottom.

Many growers use clay pebbles as a hydroponic/aquaponics growing media because they have excellent aeration and drainage properties.  

Expanded Clay Balls/ pebbles are a clean, ph stable, and can be reused a couple of times before they need to be replaced.
