There really are so many variables as Flo was saying. My big focal point is vegg times, I think that is a direct link with yield.
But some guestimates, to just give you some info, are like 1-2oz: easily achieved with the smallest dwc setups. 2-4oz id say a good avg. for any dwc plant
4+oz achieved when grown great and/or methods like lst, scrog, topping and such come in to play.
