Hydroton growing medium is an expanded clay pebble which is manufactured in Germany. While it is typically used as a growing medium for flowers and larger vegetables plants like peppers, growers of all kinds have found fantastic success from using hydroton.

One of the major advantages of hydroton is that it is a definite money saver. Unlike some hydroponic media that can wear away after a few growing seasons, or even after just a single growing season, you can use hydroton over and over again.  It will last virtually for as long as you grow hydroponically. All that is needed is to clean the pebbles thoroughly with hydrogen peroxide after each growing season and then give them a good rinse.
