Medium-grade clay pebbles (8–16 mm) for terrariums, humidity trays, and repotting mixes.
Manufactured from clay which is heated to a very high temperature to produce lightweight, hard pebbles with a smooth skin and an expanded honeycomb core.
The pebbles absorb water and then slowly release it to the plant helping to improve drainage and avoid water-logged roots. Their cellular structure also has outstanding insulating properties which will help safeguard plants from extreme temperature fluctuations.
Material: Expanded clay.
Usage: Use in repotting mixes or as a drainage layer.
Size: 3 litre bag. Pebble sizes 8-16mm.
