Legigo L-CA-Clay Ball LECA Clay Pebbles, 4mm–16mm Natural Hydroponic Medium

Porous natural clay helps balance drainage, airflow, and moisture around plant roots, making Legigo LECA clay pebbles useful in pots and hydroponic setups. The 4mm–16mm pieces can be used alone or mixed with other growing media, while their lightweight form makes them easy to pour and arrange.

Use them for orchids, succulents, terrariums, aquaponics, or indoor plants. Their rounded shape also works as a neat decorative surface layer in pots and plant displays.

Practical tips

For a potted plant, add the pebbles as a drainage layer or mix them into the growing medium to support airflow and drainage. In hydroponic applications, use them as a growing medium to support roots while their porous structure holds some water and air. They can also be used on the surface of a pot for a tidy finish.

Need a medium that helps roots access both air and moisture? The clay’s pores retain some water and nutrients, while its structure supports drainage and airflow. For reuse between plantings, rinse and dry the pebbles before using them again. The resealable pouch helps keep the remaining media clean and dry in storage.

How can I reuse them? Rinse and dry the pebbles between uses for repeated planting and repotting.

Buying verdict
