ABSTRACT:
An automatic self-regulating water control arrangement in a unique structural planter configuration that is suited to an economical and yet fool-proof method of manufacturing. A vacuum control in combination with capillary action is necessary to properly dispense the moisture required, and the final sealing of the water reservoir provides the secure vacuum means needed and permits conclusive testing of the vacuum before putting into use.
