Two pound bag of clay pebbles

This listing is for a 2lb bag of expanded clay pebbles, often referred to as Leca. The pebbles range in size from 4mm to 16mm, providing a varied texture that is excellent for drainage. This small bag is ideal for topping off a few pots or for use in a small desktop hydroponic kit.

The clay balls are kiln-fired, which causes them to expand and become porous. This internal structure allows them to wick up nutrient solution while keeping the surface relatively dry. They are a popular choice for semi-hydroponic setups where plants are grown in decorative glass containers or specialized pots.

These pebbles are pH neutral and do not break down over time, meaning they can be cleaned and reused for multiple growing seasons. They provide excellent aeration for roots, which is necessary for healthy plant growth. This set is a good starting point for those experimenting with clay media for the first time.
