AquaSprouts® Lightweight Expanded Clay Aggregate (LECA) Pebbles

Premium LECA that creates the ideal foundation for robust, vibrant plant growth in any setup.

• Porous structure ensures exceptional root aeration and drainage, preventing root rot and promoting vigorous growth

• Absorbs and retains moisture, releasing it to roots as needed for a balanced and consistent water level
• Economical and eco-friendly, these pebbles can be cleaned, sterilized, and reused for many growing cycles
• The sterile nature of LECA naturally deters common pests and diseases, keeping plants healthy
• Lighter than gravel, making it ideal for hanging baskets, rooftop gardens, and other applications where weight is a concern

Trust the same grow media included in every AquaSprouts® Garden and Fountain kit. LECA is a natural medium of kiln-fired clay, expanded into a porous, lightweight structure that anchors roots while boosting aeration. Because these pebbles are inert, and never decompose, they create a uniquely stable and lasting environment for healthy plant growth.

Versatile applications include:
Aquaponics: Acts as an excellent filter media for beneficial bacteria and a stable root base, creating a balanced ecosystem for both fish and plants.
Hydroponics: Ideal for all hydroponic systems (including Drip, Ebb & Flow, DWC, and Kratky); provides excellent support, aeration, and drainage for plant roots in a nutrient solution.
Bioactive terrariums: Use as a base drainage layer (false bottom) to prevent waterlogging, manage humidity, and provide a surface for beneficial bacteria in a self-sustaining ecosystem.
Soil amendment: Mix with soil to improve aeration and prevent compaction.
Top dressing: Use as a decorative layer to retain moisture and deter pests.
Full soil replacement: A clean, soil-free alternative for growing potted plants.
