Could you pm me some more photos and information on this setup? I have been working on a dwc setup- I would love to have a conversation with you about it. Silly, but I want a 2 pot recirculating system for a legal tent grow at home and a larger hobby build at the new shop.
I can PM as well but there is a thread I built for a complete DIY setup for an 8 bucket RDWC UC system in the hydro topic forum. It is cheap to build (minus the chiller) at about 300-350 US for a 8 site. However, I would suggest adding the modifications that Heisenbubble shows such as two 2" exits to the control (epi) bucket etc. It can be sized to anything from 2 buckets to 16 or more. Easy as hell to build and very effective and durable. These systems are easy to run as well if you have a chiller and your environment is well controlled. I could leave my room for 1 - 2 weeks and not worry because there is a top off reservoir (not shown in the original design but easy to add).
The system shown below id for very short veg cycles but in the room it is currently in I could go to 4 buckets or even two depending on how long I let them veg before I move them into the flower room. I have a UC setup in veg as well....
