Automatic plant watering apparatus
This is an award winning product which is now fully developed for the $1.8bn plant care industry. I am looking for a manufacturer to distribute the product.
An automatic plant watering apparatus is described in which a plant's growing medium is maintained uniformly moist. A one-piece water-holding body used in conjunction with a moisture-sensitive valve. The water-holding body includes a central filling chamber flanked by two reservoir chambers. A continuous air duct surrounds the periphery of the two-reservoir chambers and filling chamber. One end of the duct is coupled to a capillary plug which operates as a moisture-sensitive valve. By controlling the conducting of air ambient pressure is utilized to regulate the flow of water from the reservoirs into the planting medium.
