Vermiponics
Vermiponics is a soil-less growing technique that combines hydroponics with vermiculture by utilizing diluted wormbin leachate ("worm tea") as the nutrient solution as opposed to the use of fish waste (as used in aquaponics) or the addition of manufactured chemicals to provide the nutrients. In 2008, Saginaw Valley State University in Michigan was using vermiponics as part of its efforts to reduce waste.
