If you tried to do a sog in dwc you would have to maintain a bunch of individual buckets which is a lot of work.
This is true.
You could try doing a bunch of small plants in a giant res or rdwc/ucdwc but I would still think aero would have the advantage for sog.
Agree again--I run medium less aero using 6"x10' schedule 40 pvc pipe. I thought u were implying aero was not suitable for large plants ( I start flowering veg plants 3-4' tall).
I have heard in a proper aero setup, root growth speed can't be beat. I have never done aero so I don't know.
IMO, if done correctly----aero is the most effective nute delivery method we have. I've run aero for years.
