LECA (Lightweight Expanded Clay Aggregate) is a highly versatile and innovative growing medium designed to provide plants with the optimal environment for healthy growth and development. Made from expanded clay pebbles, LECA is a sterile, inert, and pH-neutral medium that can be used in a variety of applications, from indoor and outdoor container gardens to hydroponic and aeroponic systems.
Key Benefits of LECA:
Excellent Water Retention: LECA's porous structure allows for optimal water retention, reducing the need for frequent watering.
Improved Aeration: LECA's pebble-like structure promotes excellent aeration, allowing roots to breathe and thrive.
Increased Root Growth: LECA's sterile and inert properties prevent the growth of harmful bacteria and fungi, promoting healthy root development.
pH-Neutral: LECA is pH-neutral, eliminating the risk of pH imbalances and allowing for precise nutrient management.
Re-Usable: LECA can be re-used multiple times, making it a cost-effective and sustainable growing medium.
Sterile and Pathogen-Free: LECA is sterile and free of pathogens, reducing the risk of disease and promoting a healthy growing environment.
HOW TO USE LECA?
1. Rinse the LECA thoroughly
LECA comes dusty and dirty from the bag.
Place it in a colander or bucket and rinse with warm water several times until the water runs clear.
2. Soak the LECA
Soak it in water for 12–24 hours.
This helps it absorb moisture and sink properly (some balls float when dry).
3.Prep your plant
Gently remove the plant from its current soil.
Rinse off all soil from the roots — be thorough, especially for semi-hydro use.
4. Place LECA in a container
Add a layer of LECA at the bottom of a pot (use a pot without drainage holes for semi-hydro, or with for passive LECA use).
Position your plant in the center.
5. Fill in with more LECA
Carefully fill around the roots with LECA to hold the plant in place.
Make sure the roots are supported but not tightly packed.
6. Add water
For semi-hydro: Fill the pot with water until it reaches just below the roots (not soaking them).
Optional: Add liquid nutrients to the water (like hydroponic fertilizer).
7. Maintenance
Top off the water when it gets low.
Flush the LECA every few weeks with clean water to avoid salt buildup.
