Love this show. Love watching it. I've done garden beds for my wife and mother in law. I just can't figure out how to make it self watering due to the fact we don't get enough rain to do a rain catchment system. And I don't want to hook to city water cause it will run up water bill. Any advice would help. We live in a residential neighborhood. So I need to do something that's easy to build at a low cost. Also we love Missy's ideas she does for garden beds and greenhouses. Still haven't figured out how to build one of those yet.
