I have a 20 site cloner I can make some pics of that people shouldnt have any prob duplicating. also refinements to an 8 site waterfarm that I have been thinking of for a while. the problem I see with a waterfarm is the water from the controller doesnt circulate through the whole unit and the top off water in the res gets nasty fast. Maybe have gravity feed tubes to each unit from the reservior with a pump at the controller puming the nutes back up to the res. that way the water flows from the buckets back to the controller and there wont be any stagnant water in the system. the unit would have to be syncronized with the flow rates so it doesnt overflow anything though.
