In modern hydroponics, growers across Australia and New Zealand are increasingly choosing expanded clay aggregate, commonly referred to in the market as LECA clay pebbles. This growing medium has become a trusted solution for growers who want healthy roots, consistent moisture, and long-term reusability.

Expanded clay aggregate is produced by firing natural clay at high temperatures, creating round, lightweight clay balls with a porous internal structure and a hard outer shell. This structure allows roots to breathe while maintaining optimal moisture levels, a key requirement for hydroponic success in both warm Australian climates and cooler New Zealand environments.

Unlike organic growing media, expanded clay aggregate is 100% inert, sterile, and pH neutral, making it ideal for nutrient-controlled hydroponic systems. It does not decompose, compact, or introduce pests, allowing growers to reuse it season after season with minimal maintenance.

For hydroponics, the 8–15 mm size range is widely preferred. It provides excellent drainage, strong root anchoring, and even nutrient distribution, making it suitable for NFT systems, drip irrigation, aquaponics, and indoor grow setups.

At Rivashaa Eco Design Solutions, we manufacture and supply high-quality expanded clay aggregate designed specifically for professional and commercial hydroponic applications, supporting growers across Australia and New Zealand with consistent quality and bulk supply.
