Hydro leca clay pebbles 2.5l (terrarium base layer/false bottom)

LECA, which stands for Lightweight Expanded Clay Aggregate, is a popular and versatile growing medium that is often used in gardening and horticulture, including terrariums. It consists of small, round, and lightweight clay pellets that are created by heating clay to high temperatures, causing it to expand. LECA has several properties that make it well-suited for use in terrariums:
Excellent Drainage: One of the key benefits of LECA is its exceptional drainage properties. It allows excess water to quickly pass through the substrate, preventing waterlogged conditions that can lead to root rot and other plant issues.
Aeration: LECA pellets have air pockets within them, which helps provide oxygen to plant roots. This aeration is crucial for healthy root development and overall plant growth. Moisture Retention: While LECA provides good drainage, it also retains some moisture within its structure. This helps maintain a consistent level of moisture around the roots of the plants, preventing them from drying out too quickly. Stability: The pellets are lightweight yet stable, providing a sturdy base for plants to anchor their roots. This stability is important in terrariums where plants may be moved or rearranged. pH Neutral: LECA is typically pH neutral, which means it won't significantly affect the pH of the terrarium environment. This can be beneficial for a wide range of plants that prefer different pH levels. When using LECA in terrariums: Bottom Layer: LECA is often used as a bottom layer in terrariums to create a drainage layer. This prevents water from accumulating at the bottom and causing root rot. The LECA layer is typically a few inches thick. Barrier: A thin layer of horticultural fabric or a fine mesh can be placed on top of the LECA layer to prevent the potting mix from mixing with the LECA. Potting Mix: On top of the barrier, you can add a layer of appropriate potting mix for the plants you are growing. This layer contains the necessary nutrients for plant growth. Planting: Plant your chosen terrarium plants in the potting mix layer. The LECA layer will help provide proper drainage and aeration to the plants' roots. Decoration: LECA can also be used decoratively as a top dressing in your terrarium to cover the soil and give a neat, finished appearance. LECA is particularly well-suited for plants that prefer well-draining soil conditions, such as succulents, cacti, air plants, and many tropical plants. However, it's important to research the specific needs of the plants you intend to grow in your terrarium and adjust your setup accordingly.
