Applications:
LECA pebbles have a wide range of applications in gardening and plant care. Here are some popular uses:

•    Hydroponics: LECA pebbles are an excellent growing medium for hydroponic systems. They provide good aeration and drainage while being inert, meaning they don't release any harmful materials into the water.
•    Orchid Growing: Orchids thrive in well-aerated environments. LECA pebbles are often used in orchid cultivation to provide excellent drainage and airflow around the roots.
•    Soil Amendment: Mixed with potting soil, LECA pebbles improve drainage and aeration, making them ideal for plants that prefer well-drained soil, such as succulents and cacti.
•    Propagation: LECA pebbles are used in plant propagation, especially for cuttings. They provide a stable and moisture-retentive environment that encourages root growth.
•    Aquaponics: LECA pebbles are used in aquaponics systems, where they provide a substrate for plant roots and help filter water while housing beneficial bacteria.
•    Mulch: LECA pebbles can be used as a decorative mulch on the surface of potted plants to retain moisture and prevent soil from drying out too quickly.
•    Self-Watering Pots: LECA pebbles are often used in self-watering pots as a wicking medium that draws water up to the plant roots from the reservoir.
•    Green Walls and Vertical Gardens: LECA pebbles are used in the growing medium for green walls and vertical gardens, providing lightweight support and good drainage.
•    Terrariums: In terrariums, LECA pebbles are used as a drainage layer to prevent water from pooling at the bottom and causing root rot.

With so many applications, LECA pebbles are a versatile and valuable addition to any gardener's toolkit.
