The original Hydroton® brand expanded clay is a unique, lightweight expanded clay aggregate made in Germany. This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Clay naturally has balanced capillary action, with an ideal surface structure. Hydroton® brand expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. 50 liter bags feature an easy pour spout. The size specification for Giant™ Hydroton® is 15-25 mm.

Great value
Very dusty and need to wash it before use. Most of them float in the water at first but seem ok after they are soak in water for a while. I brought other brand but their pellet size is small compare to this one.

Lightweight filler
We used these pebbles to help fill really large planters. They were perfect to help allow drainage and keep the pots from being so heavy! Great product.

It's more trouble than dirt
Put in pots does not hold water like said roots grow in it very well

Recommend for hydroponic or aquaponic systems
Using in my hydroponic setup. Working great. Pricy but seems to be worth the price.
