AutoPots are not simple: moving parts/valves, plumbing, requires a central reservoir (with all its problems), etc.
Consider passive self-watering bottom-feeding bases, such as the "Self-Watering Fabric Pot Base" from AC Infinity. I currently use these, and the plants grow much bigger than manually feeding; I presume much the same as with bottom-feeding AutoPots. You just place normal, such as 3 or 5 gallon, fabric bags, on the base that has rope wicks dipping into the reservoir below, with the coco/perlite wicking up the feed water from the base via the rope/wicks at it needs it. All you have to do is fill each base/reservoir, that holds a gallon.
