RDWC PERPETUAL GROW PROBLEM

I have a three part perpetual grow going right now with a 2x4, 4x4, and 8x4 tent. I’m running dwc single bucket system right now and it’s a bitch to change each individual bucket seeing as I’m running 8 5gal buckets in flower and 8 in veg as well as my rockwool cubes. I was planning on switching over and making my pre owned buckets into rdwc but I haven’t seen a rdwc system with 8 5gal buckets in a 4x4 before. I have room on the outside of the tent for the control bucket and Rez. So my question is, is it possible to have a rdwc system with 8 5gal buckets in a 4x4 or am I better off just making my 8x4 into rdwc and keeping my veg tent as dwc. Any help or similar experience would be appreciated thank you.

Scaling up in dwc becomes a pain in the ass. Rdwc has more failure points as well as more heat added to the water. Most rdwc use a chiller to control water temps.

I loved growing dwc when I was only doing a few plants but in my opinion it's a pain when doing more than that.

You could use tubs instead of buckets and do 2 plants per tub. That would cut down the amount of containers to change the water out in.
