This is the newest bed in the greenhouse. Wicking beds are going to be the big "new thing" in aquaponics, because of their ability to grow root crops and fruiting plants not grown before in soilless and raft systems. Solid waste removal is less of a problem because solids are used to feed worms in the beds and are removed by this method.
