Frequently Asked Questions
Q: What are the primary benefits of using LECA in hydroponics?
LECA provides excellent aeration and drainage, preventing root rot while supporting the root structure, making it ideal for nutrient-film techniques and deep water culture.
Q: Is this expanded clay suitable for construction use?
Yes, due to its high strength and thermal insulation properties, LECA is widely used in lightweight concrete and construction insulation projects.
Q: How is LECA different from standard gardening clay?
Unlike standard clay, LECA is expanded under high heat, creating a porous internal structure that allows for air and water movement, preventing the medium from becoming a solid mass.
Q: What is the typical lead time for a 20ft container order?
Our standard delivery time is approximately 15 days from the date of order confirmation and payment.
Q: Can these clay pebbles be reused?
Absolutely. Because LECA is an inorganic mineral product, it does not decompose. It can be cleaned and sterilized for repeated use across multiple growing cycles.
Q: Do you provide custom packaging for retail brands?
Yes, we offer OEM label services and customized packing sizes to meet the branding and marketing requirements of our international clients.
