ABSTRACT:
A measured and variable quantity of water is delivered to an object requiring periodic watering when a water filled vessel is inverted and mounted or suspended above the item requiring water. The vessels constricted orifice is sealed by a rubber stopper which has two holes into one of which is inserted a tube filled with water soluable material and the other of which contains a hollow vacuum breaking tube long enough to support the entire apparatus in reasonably giving material (sand, dirt, gravel, etc.). A tripod stand is also provided to suspend the device if such giving material is not present. As the soluable material is immersed in water by inverting the device the dissolution process begins and when all of the material in the tube has dissolved the contained water is set free through the dissolutime time tube. Timed control of 1 to 15 or more days is achieved by providing filled tubes of various lengths.
