Anyone made the jump from DWC to RDWC?

Running a 4x4 with four 5-gallon buckets in a standard DWC setup right now. EC sitting around 1.4-1.6 in late veg, pH locked at 5.8, and things are working fine. But i keep reading about RDWC delivering more consistent dissolved oxygen and tighter EC/pH across all sites, and i'm starting to wonder if my bucket-to-bucket variance is silently costing me grams. My main concern is the plumbing complexity and the extra failure points. Adding a reservoir, circulation pump, and connecting lines in a 4x4 sounds like it eats up space fast and introduces more leak risk. I've seen builds where the controller bucket sits outside the tent, which helps, but now you're running lines through the tent wall and dealing with heat from the pump. For anyone who made the switch, was the improvement in root health and yield measurable enough to justify it? Or is it mostly theoretical and a well-managed DWC hits the same numbers? Any specifics, like actual wet weight differences or notable EC stability improvements, would be really useful to hear.

Coming at this from a different angle than most people probably told you -- i run RDWC now but honestly the gains i noticed most weren't yield related at all, they were terp related. More consistent DO and stable EC meant less stress spikes during flower, and stressed plants in my experience get loud but not in a good way. Stress terps are a thing and they're usually not the ones you want. That said, the "silent variance killing your grams" thing is a bit overhyped in my opinion. A well-dialed DWC with daily top-offs and checks is not leaving much on the table. The people seeing massive jumps from DWC to RDWC were probably also just getting better at growing in general over that same time period. The pump heat issue is real though. My circulation pump added a couple degrees to my reservoir temps and i had to actually upsize my chiller to compensate. Nobody talks about that part. If your res temps are already marginal that's a real consideration before you rip out a working setup.
