What it is: LECA is a round-pellet structure created by firing natural clay at high temperatures. This process causes the clay to expand and form a porous, honeycomb-like structure.

Uses: It is commonly used as a soilless growing medium for plants in hydroponic systems, as well as in aquariums, roof gardens, and for bonsai cultivation.

Properties: LECA is lightweight, breathable, and has good water absorption and drainage properties. It is also pH-neutral and thermally insulating.

How it works: The porous structure helps to absorb water and nutrients, which are then released to the plant roots. It also provides aeration, which is crucial for healthy root growth.
