Hydroponic Expanded Clay Growing Media

Take your hydroponic setup to the next level with Expanded Clay Pebbles (LECA), the professional-grade growing media trusted by growers worldwide. Designed to pair perfectly with TexasHydroTowers, this 10 L bag of 8 mm pebbles is enough to fill 2 full-size 6-ft towers (20 sites each) or ~30 pods.

Unlike soil, LECA delivers the ideal balance of moisture retention and oxygen flow, ensuring your roots never drown or dry out. The porous structure absorbs nutrient solution, then slowly releases it back to the roots, creating a steady feeding cycle that produces faster growth, bigger yields, and healthier plants.

Whether you’re growing herbs, leafy greens, or tomatoes in your TexasHydroTower, expanded clay media provides the clean, reusable, pH-stable foundation your system needs.
