LECA consists of baked clay pellets with a porous structure that retains water and air simultaneously, providing excellent root oxygenation while preventing compaction. In cannabis cultivation, it serves as a stable, reusable substrate for hydroponic systems. Its neutral pH and inert properties make it easy to manage nutrient delivery, though growers must monitor salts to avoid buildup. Curious how these tiny balls revolutionize root health? Explore LECA’s role in modern hydroponics.
