Hydroton 50 Liter Bag
Dividing the world above from the world below, the interface between a plant and its roots is where media come in. The magic of hydroponics happens in the world below, the domain of the roots.
Over the years many different kinds of media have been used for hydroponic cultivation - gravel of many kinds, mineral fiber (rockwool and glass fiber), sand, sawdust, expanded glass (perlite), vermiculite, plastic foam and a host of other inert media have been tried. Following over twenty years of experience we have settled on a few different kinds of media for different applications and rejected many others because they have proven problematic.
Hydroton is our trade name for "expanded clay," a lightweight gravel which is manufactured specifically for hydroponic cultivation.
This media is the first choice for many commercial Dutch growers specializing in flower and vegetable cultivation. Not to be confused with many other kinds of expanded clay which look similar but which are often toxic, Hydroton is pH stabilized and releases practically no minerals into the nutrient stream; in other words Hydroton is almost completely inert.
