Lightweight clay pebbles for flower pots

These listings offer a ten pound supply of expanded clay aggregate, often referred to as LECA. The pebbles are sized between 4mm and 16mm, providing a balanced mix for supporting plant stems and allowing for air pockets. This medium is particularly effective for flowering plants that need a combination of moisture retention and high drainage.

The clay balls are lightweight, which makes handling large pots much easier compared to using traditional stone or heavy soil. They are fired in a kiln to create a hard outer shell with a honeycomb-like interior. This structure allows the pebbles to wick up water and nutrients, releasing them slowly to the roots as needed by the plant.

Using this medium helps to minimize the risk of pests that are commonly found in organic soil. The pebbles are clean and do not break down, ensuring that the root zone remains airy and healthy over time. They are suitable for use in decorative glass containers, hydroponic buckets, or as a soil amendment to increase porosity in heavy mixes.
