Rinse and Soak: Before using LECA for the first time, rinse the balls thoroughly to remove dust and debris.Then, soak them in clean water for at least 24 hours to allow them to absorb moisture.Some people do a second or third soak to remove more impurities.
Clean the Plant: If you are transitioning a plant from soil to LECA, carefully remove all soil from the roots.Any remaining soil can cause root rot in the wet LECA environment.
Potting: Place a layer of LECA at the bottom of a pot, then position the plant, and fill the rest of the pot with more LECA.Using a clear container can help you monitor water levels and root health.
2. Watering and Nutrients:
Watering: LECA acts like a sponge, absorbing water and releasing it slowly to the plant’s roots.In a semi-hydroponic setup, you can water by filling the bottom third of the pot with water.The LECA will wick the water up to the roots.
Nutrients: LECA is an inert medium and contains no nutrients.You must provide all necessary nutrients for your plant through a liquid fertilizer or a hydroponic nutrient solution.You can add a diluted fertilizer solution to the water reservoir.
Flushing: Over time, mineral salts from water and fertilizers can build up on the LECA.Periodically flushing the LECA with clean water can help remove this buildup.

3. General Care:
Monitor Water Level: Keep an eye on the water level and refill it as needed.Do not let the LECA completely dry out, as this can cause it to wick water away from the roots.
Pest Control: LECA can help reduce common soil pests like fungus gnats, as they thrive in organic matter.
Reuse: LECA is reusable and can last for years.To reuse, you can rinse and sterilize the balls to prevent the transfer of any pests or diseases to new plants.
Algae: Algae can grow on LECA, especially in clear containers exposed to direct sunlight.While not always harmful in small amounts, it can be unsightly.
