LECA — Lightweight Expanded Clay Aggregate for Semi-Hydroponics

Lightweight and reusable, Leca wicks moisture from a reservoir while maintaining airflow around roots. The porous spheres help balance moisture, making them ideal for propagation, semi-hydro systems, or as a base beneath soil. In semi-hydro, pair with a self-watering pot for consistent hydration. Easy to rinse and reset, Leca supports cleaner, low-maintenance growing. Why Choose Leca? 1. Moisture Wicking, Without the Guesswork: Leca draws water upward from a reservoir while keeping roots surrounded by air—supporting steady hydration without waterlogged conditions. 2. Ideal for Semi-Hydro & Propagation: Perfect for cuttings, transitioning plants, and semi-hydro setups—especially when paired with a self-watering pot for consistent results. 3. Clean, Root-Healthy Airflow: The porous clay spheres maintain space between roots, improving oxygen access and helping reduce the risk of rot. 4. Reusable & Easy to Reset: Rinse, sterilize, and reuse—Leca is designed for repeat use, making it a cleaner and more sustainable alternative to disposable mixes. 5. Flexible in Any Setup: Use it as a standalone medium, a drainage layer, or a base beneath soil to improve airflow and moisture balance across a wide range of plants.
