RDWC is a very miss used term and does not by any means imply that you have a single res system with many sites. If you google RDWC you mostly find stuff that is not RDWC. Most people using the term are not fully aware of what it means and are calling something RDWC because the nutrient solution is being recirculated...but that does not mean it is an RDWC. RDWC is a specific type of recirculation and is most commonly done in a single site bucket.
You can do an RDWC with a single site res by ganging the buckets together and that makes it easier to deal with. However you then need understand that all the plants in the system have to be on the same life cycle. Preferably the same strain. This is because they all get the same nute solution. in order to keep them all happy they must be having the same needs. It complicates things to run a sativa and an indica in the same res when the life cycle is 4 weeks different. Do you start to shut down bloom nutes too early to not burn the indica or do you shut it down right for the indica and make the sativa suffer and be weak?
All ganged systems are intended to run clones of the same strain at the same age so you run a solution optimized for all the plants. It is much easier to deal with but at the same time you gotta crawl before you walk. I stress this often and I say for beginners to go with single site solutions so when they screw up the one plant the others don't suffer. Start small with just 2-4 plants running single buckets and learn about the process. This way you can run from seed and if they sprout a week apart it aint no thang.
Once you know about a lot of things I wont list here and know how to run a good stable living solution you can start ganging those together (yes the same buckets can then be retrofitted into a system) and start running clones together.
Recirculation in terms of Hydro specifically means reintroducing the nutrient solution to the top of the res. The history on this is nutrients in the solution are heavy. If you do not do something then they will all settle on the bottom of the res and the res will have issues. So you pump from the bottom of the res to the top of the res.
I splained it all once here with links and videos...(wow in 2 days that was a year ago...)
