I love my RDWC setup, its as easy as it gets, the only downside I have found is it grows to big until you learn how to do it. A chiller and PH dosier makes it or breaks it. 2 things you learn real quick in RDWC, 1) Short Veg 4 weeks is too much. 2) Never grow autos. Nothing to do with RDWC just dont do it.

  Oh I ran 2 grows the first was so good I was ready for another, and it was a nightmare. pH was all over the place. Didn't matter what I did. It would either rocket out of control or crash so hard I had to get a new meter just to be sure it was an accurate reading! There was a week towards the end I had to change out the water 3 times at about 40gals a throw gets expensive, , RO doubly so. But in the end they made it so I am exploring other methods. I may end up back in dwc because it does work really well just the bad experience fresh in my head has me steering away for a time.

  RDWC without a dosier could be tough and water temperature changes can mess with the PH too. I have a reservoir for my coco auto feed and another for my Ebb & Flow that dont have dosiers but once I dial it in the PH usually holds, if anything the PH goes up. The RDWC has the doiser and the PH goes down down so much I will use a gallon of of PH up in a grow.
  
  If your having trouble with RDWC then I dont thing DWC will be any easier. In the long run I think coco coir and an auto feed system is the way to go.
