I have no experience with auto watering system BillMonroe but I can give info on what I would do if I wanted to set up something like that. I would get a reservoir of some sort let say 5 gallon bucket for this example. Get a submersible water pump, a timer to set when pump to water, some 9-inch halo water ring, some t fittings, and Hydro Flow Barbed Ball Valves. Put Hydro Flow Barbed Ball Valves between Halo ring and t fittings to control water flow so you can even out watering to each container.
