Legigo L-CA-Clay Ball LECA Clay Pebbles, 4–16 mm, 2 lb

Some plant setups need a loose, airy growing medium, while others benefit from better drainage or a tidy decorative top layer. Legigo Leca Clay Pebbles can serve those different roles: use them on their own for hydroponics, mix them with other growing media, or place them in a pot as a drainage layer or surface covering.

Made from natural clay, the lightweight, porous balls measure 4–16 mm and are suited to small and medium pots, orchids, succulents, terrariums, and aquaponic setups. Their structure supports airflow around roots while holding some water and nutrients, giving you a flexible medium for indoor plant care.

Product specs

• Brand: Legigo
• Model: L-CA-Clay Ball
• Type: Natural clay growing medium
• Size: 4–16 mm
• Weight: 2 lb
• What’s included: Leca clay pebbles in a resealable foil pouch

The pebbles are made by firing natural clay into rounded pieces. Their porous structure helps drain excess water and keep air moving around the root zone, while the pores can retain some moisture and nutrients. The clay is described as pH neutral, making the pebbles useful for plant setups where a stable, airy medium is a priority. Use them alone as a hydroponic growing medium or combine them with potting media to add drainage and airflow.

Tips for day-to-day use

Choose the arrangement that suits your planting setup: spread the pebbles over the surface for a neat finish, place them at the base of a pot to support drainage, or mix them into growing media to help keep it lighter and more breathable. For hydroponics, they can support roots while providing access to air and moisture. They are also listed for orchids, succulents, terrariums, aquaponics, and aquatic plant support. What makes them useful across these settings? Their porous structure can hold some moisture without giving up airflow.

For reuse between plantings, rinse the pebbles and let them dry before using them again. Buyers often praise their usefulness for hydroponics and terrariums, moisture management, and appearance in succulent pots. Feedback on pebble size and shape is mixed, as is feedback on dust, so rinsing before use can be a practical step when preparing a batch.

In the box

The package contains 2 lb of 4–16 mm Leca clay pebbles in a resealable foil pouch, which helps keep the growing medium clean and dry between uses.
