A wicktube can transfer liquid from one end to the other end by capillary action, and a wickswitch can control this capillary liquid transferring action. Wicktubes are connected together to form a wickhub. A wicknet combines wickhubs, wicktubes, and liquid reservoirs to form a network. Wickconnectors connect the elements of the wicknet. Wicknet and wickswitches can control the liquid supply of the plants in a garden or farm. This liquid supply control can be precise if electronic controller and some sensors are added. It is simple, slow and clean. And it uses only minimum amount of liquid. Plants can be hung on the wall to form a garden on the wall, a hanging garden.
