Halatool 2 lb Expanded Clay Pebbles (4-16mm) for Hydroponics | Leca Balls

Halatool 2 lb Expanded Clay Pebbles deliver a reliable, inert growing medium that supports a wide range of plant care scenarios, from compact hydroponic systems to decorative setups. The pebbles are formed by firing clay at high temperatures, creating a durable substrate that resists breakdown and stays relatively light even when damp. The 4–16 mm size range offers flexibility: smaller grains cradle delicate cuttings, while larger pellets provide sturdy drainage and visible air spaces for healthy roots. The porous, ball-shaped texture invites air to circulate around the root zone and helps excess water move through the medium, reducing the risk of overwatering in soil-free systems. In practical terms, this means you can tailor your medium to orchids in net pots, Dutch bucket configurations, terrariums, and aquaponics setups without changing the fundamental substrate. The result is a dependable base that supports steady root development while keeping reservoirs cleaner and surfaces drier than heavy soil-based media.
