Most suitable technique for perpetual harvest is old school separate pots (with soil or coco). This way you can manage each plant individually. You can still use drip for irrigation to your advantage.
I can’t really see easy way to do perpetually bubbler/dwc, I think they are not much compatible. I’ve tried SOG with E&F and also don’t think this works well with perpetual, because it is prefereable to have whole E&F table covered (not as open space - because of algae). This fact makes removing / adding plants difficult.
It is easier to also to have mothers in pots imho because you can manipulate them and do cutting and maintenance easily.
