Type:Expanded Clay
Hydro Clay starts with the highest grade natural clay following a strict grading formula and is assembled via granulation method.
By following this process we guarantee that you get a more consistent spherical shape and size with a more uniform and rigid structure that resists breaking.
You get a consistent 8-16mm round shape that is rigid and made from 100% freshly mined raw clay material free of impurities and ready to use straight out of the bag.

PLEASE NOTE: 1L of Clay Balls does NOT equal 1kg in weight. We measure in L because the pots they go into are in Litres. As in if you have a 15L pot, then you need 15L of Clay Balls or Soil or Coco or Perlite to fill it. Yet 15L of Clay Balls weighs different to 15L of Perlite or 15L of Soil or 15L of water or even 15L of feathers!! We sell in Literage not Kilogram!!
