Hydrogranule Clay Pebbles 8-16mm

Hydrogranules are used in hydroculture planting. These clever little granules are manufactured from baked and expanded clay pellets and provide hydroculture plants with optimum conditions to thrive, as well as providing improved drainage and root aeration when used with potting mixes.

Our hydrogranules are certified for horticultural use and made from purified and homogenised baked clay. They are triple filtered to remove dust and undersize pebbles and they also have a lower bulk density than clay pebbles of other brands, which means they are more porous and have a better ability to retain water. Our pebbles are also irregularly shaped, increasing their surface area compared to rounded pebbles thus allowing the plants more contact with nutrient solutions.
