38 recirculating deep water culture diagram
Much like it's cousin, the bubble bucket, the recirculating deep water culture system (RDWC, better known as DWC) quickly grows plants in a near ideal environment. The main difference is that the system supports multiple sites and allows you to grow a much larger crop of the same plant with far easier maintenance. 1. Components of the Deep Water Culture Aquaponic Unit (DWC) 1.1 Water flow In the deep water culture unit described in this technology, water flows by gravity from the fish tank, through the mechanical filter, and into the combination biofilter/sump. From the sump, the water is pumped in two directions through a (Y) connector and valves. The recirculating deep water culture, or RDWC for short, is a beefed-up version of the traditional DWC method . The system works somewhat like a hybrid between a classic DWC system and the flood-and-drain hydroponic technique. It's not considered an ebb-and-flow system, however, because the water is never drained completely...
