Cool. Anything can be hydro media. Gravel from a driveway would work. So does sawdust. Straw bale gardening is a type of hydro; so are sub-irrigated planters. Defining hydro simply as soil-less would make it include most container gardeners, because pro-mix and other grow media does not contain actual dirt.
