Green Planet Expanded Clay Balls 8–15 mm (25 L)

The Green Planet Expanded Clay Balls 8–15 mm (25 L bag) provide a clean, stable growing medium for hydroponics, aquaponics, or soil mixes. These lightweight LECA pebbles offer excellent moisture retention while maintaining strong aeration around the root zone. Because of their unique structure, they help prevent waterlogging and promote healthy, oxygen-rich growth.

Made from 100% natural clay, these pebbles are pH-neutral, sterile, and non-degradable. They won’t break down or affect your nutrient solution over time. Their inert nature makes them ideal for virtually any grow system, from ebb-and-flow to deep-water culture.

Their high porosity feeds both air and moisture to roots efficiently, enhancing nutrient uptake and supporting vigorous microbial activity. Because the balls are non-degradable, you can rinse, sterilise, and reuse them across multiple grow cycles, making them cost-effective and environmentally friendly.

When preparing these clay balls, rinse them thoroughly before first use to remove dust. Once clean, they can be used in net pots, as a top dressing, or as the primary medium in your grow system. Their size (8–15 mm) offers an excellent balance: large enough to avoid compaction, yet small enough to create a stable structure around roots.
