Vermiponics - Hydroponic Worms
Aquaponics took hydroponics to a new level, it is basically a fish tank that doubles as a Garden. The fish waste is used as fertilizer and the fish tank is kept clean while the plants thrive - a mutually beneficial relationship.
The person credited with pioneering vermi-ponics is Jim Joyner of Tennessee.Building onto Joyners concept is Bentley Christie of RedWormComposting.com, Christie has been experimenting with adding materials such as cardboard and lint to provide the worms a more suitable environment as well as more organic compost. He publishes updates at RedWormComposting.com.
Another issue I encountered when experimenting with this setup is that worms are periodically washed into the solution and subsequently drown. Their decomposing carcasses break down and should do no harm so far as effecting the nutrient composition. However, if your channels and conduits are not large enough you may find them clogged with a dead worm or two.
Although vermiponics is in it's infancy, a relatively new discipline within the Hydroponic Real, a recent study has shown that in it current stages that "Red wiggler worms had no immediate, consistent and demonstrable benefit as far nutrient concentration, system stability, or plant yield, and that fish species had more effect on system solution."
