hydro grains

Hydro grains, also known as LECA (Lightweight Expanded Clay Aggregate) or hydroballs, are small, porous balls made from fired clay used as a growing medium, drainage layer, and decorative element in gardening and hydroponics. They improve soil aeration, prevent waterlogging by draining excess water, reduce pot weight, and help maintain a consistent moisture level, making them suitable for both soil-based pots and soilless hydroponic systems
