The AutoPot is a gravity feed self watering planter. Since the system is gravity fed you have no need for a pump. By connecting the 1/4 Inch feeder tube to the reservoir placed at a higher elevation than the auto pot. The aqua valve will automatically water the plant as needed allowing dry periods so that the plants are not over watered reducing the risk of obtaining root rot and other disease and pest infestations common with over watering. AutoPots are good for use both indoor and outdoor as well as for growing ornamentals or edible plants. The AutoPot dual is the same as the auto pot single except it is a two plant system. Both square containers are 1.93 gallon that fit into a dual cavity tray providing automatic watering through the same gravity feed concept.
