Hydroponic Clay Pebbles (8mm To 16mm Expanded Clay) is ideal for using with humidity trays for orchids and all other plants. These clay pebbles can be used for semi-hydroponic culture for orchids or as a potting media on its own.
Can also be used with drip trays of any size or as a drainage layer in pots or for flood and drain systems.
Like some clay spheres which are very light weight these have a bit of weight to them which will help prevent pots falling over if you try as a potting media and its irregular shape will help prevent them rolling everywhere if you do spill.
This product looks very comparible to other highly branded clay pebbles.
