Small five to ten millimeter clay pebbles

This specific set of clay pebbles features a smaller diameter, ranging from 5mm to 10mm. The smaller size is ideal for starting seeds or for use in smaller net pots where larger pebbles might not fit well. These clay balls provide a dense but breathable support structure for delicate root systems in various hydroponic setups.

The pebbles are manufactured to be durable and resistant to crumbling. Their uniform small size makes them excellent for wicking moisture upwards in semi-hydroponic arrangements. They are often used in decorative planters to cover the surface of the soil, which helps to retain moisture and provides a clean, finished look to indoor potted plants.

Because these pebbles are inorganic, they do not provide a food source for fungus gnats or other common indoor garden pests. They are easy to sterilize between uses by boiling or soaking in a cleaning solution. This makes them a reliable and repeatable component of a gardening toolkit, especially for those focusing on small-scale propagation or decorative greenery.
