These lightweight clay pebbles are a brilliant base layer for terrariums, semi-hydro setups, or pots without drainage holes. LECA (Lightweight Expanded Clay Aggregate) allows water to drain away from roots while still providing ambient moisture, creating a healthier root zone and helping prevent rot. You can also use them to aerate chunky soil mixes or as a stand-alone substrate for propagation and hydroponics. Rinse before use and enjoy fuss-free, breathable foundations for your plants. Show more
