Hi eggmansky, RWDC is Recirculating Deep Water Culture. DWC can be as simple as a bucket of water. I am currently using DWC with a controller and a secondary res to keep my primary res topped off. I plan to continually pump the water from my primary res to the secondary res creating a RDWC system. I hope this is going to stop the algae blooms I've been having in the controller and secondaty res.

McJack,
My next grow will be completely automated with 2 buckets modified to RDWC. I've had this unit in the attic for 20 years and am prepping it now for the next grow:
