This is just a thought, i have wondered about this myself, others have probably pulled it off i would assume. Is just running lines to each plant with branches of nozzles into each pot. Prep your water res, ph it out, bubble it add nutes then just have a control valve to start watering. I don't know if this is effective or not. Might be something to look into. If you have an idea of how much each plant needs then you can gage how much water in the res you need to pre make.
