Growcery Lightweight LECA Clay Pebbles 10-16mm for Hydroponics & Plants 3L

• Large 10-16mm grade: Rounded to slightly oval expanded clay pebbles with natural variation, suitable where a coarser and more open growing medium is preferred.
• Lightweight expanded clay: The low-density porous structure adds volume and support while remaining easy to handle in larger pots, planters and growing systems.
• Drainage and aeration: Creates open spaces around roots and helps excess water move through suitable hydroponic systems, drainage layers and substrate blends.
• Versatile plant care: Suitable for hydroponics, semi-hydro growing, orchids, drainage layers, decorative top dressing and larger indoor or outdoor planters.
• Rinse before use: Some natural dust and occasional broken pieces may occur during transport. Rinse thoroughly before use and clean for reuse where appropriate.

Growcery Lightweight LECA Clay Pebbles are made from expanded clay and graded to approximately 10-16mm. The larger particles have a rounded to slightly oval form, a naturally porous surface and a particularly lightweight structure. The coarse grade creates open spaces around plant roots, helping air circulate and allowing excess water to move through suitable growing systems and substrate blends. It is well suited to hydroponic and semi-hydro growing, orchid substrates, drainage layers, decorative top dressing and larger plant pots or planters. The pebbles can be used alone in compatible growing systems or combined with other growing-media components where a coarse, open structure is required. LECA does not provide significant plant nutrition on its own, so plants should receive water and nutrients according to the chosen growing method. Rinse thoroughly with clean water before use to remove natural dust caused by handling and transportation. Particle size, shape, texture and colour are approximate and may vary. Occasional broken pieces are normal for expanded clay products. The pebbles may be cleaned and reused where appropriate.
