Clay Pebbles are made from 100% natural clay. They are clean, pH stable, and offer great aeration and drainage in hydroponics, especially in flood and drain, deep water culture, and drip feed systems. Due to their unique structure and ability to cover a large surface area, they offer the ideal environment to foster beneficial bacterial growth around the root zone, leading to naturally healthier plants.

Clay Pebbles
The round pebbles do not compress or touch. The uniform space between the pebbles provides even aeration and wetting throughout, allowing roots to fully grow into the medium. The clay surface repels water, but surface tension coats each clay ball in a thin coat of water, perfect conditions for roots. Cracked rocks absorb water like a sponge.
It is made of clay with high water storage properties and balanced capillary action to accelerate plant growth.
Why used Clay Pebbles as plants growing media?
• Extremeley stable in both pH and EC
• Made from 100% natural clay
• Strong structural integrity means that they are less likely to break and compact, which helps to prevent dripper systems from getting blocked
• Pre-washed to aid in stability
• Drain freely and do not hold any excess water, providing good oxygen levels around the root; suitable for flood and drain systems, multi-pot and drip feed systems
