Expanded clay pellets, most commonly known under the brand name LECA (acronym of light expanded clay aggregate), also known as Hydroton and under the non-proprietary terms fired clay pebble, grow rocks, expanded clay (pellets) or hydrocorns, are small globes of burnt and puffed clay, used in construction and farming, and there especially in hydroponics.
Expanded clay pellets offer good insulation (low thermal conductivity coefficient), they are lightweight and heatproof.
They are anorganic, have a neutral pH and transport and store water. The gaps between the kernels provide a good aeration (oxygen transport) of the roots.
Expanded clay pellets are used as a substrate in hydroculture / hydroponics, or as a soil additive. They can also be spread as a top layer over soil around plants to prevent the growth of unwanted weeds.
