Riare 4 LBS Organic Expanded Clay Pebbles – Leca for Hydroponics & Indoor Plants

Discover Riare's Organic Expanded Clay Pebbles, a lightweight, neutral-pH growing medium designed for hydroponics, aquaponics, and container gardening. Sized 4–16 mm, these 4 lb bags deliver consistent texture that supports drainage, aeration, and reliable moisture retention. The natural clay is baked at high temperatures, resulting in a porous, neutral medium that resists odors and dust, helping keep your plant environment clean.

Designed for practical versatility, the pebbles serve as a bottom drainage layer to prevent root rot, or as a top decorative mulch that helps maintain soil moisture between waterings. Their porous structure traps air and holds nutrients, creating a healthy rooting environment without compacting soil. Use them across orchid beds, succulents, cacti, olive trees, or as a hydroponic grow medium, aquarium substrate, or decorative accent in pots.
