Abstract
A fluid level control for a container having a space to which fluid is supplied from a reservoir. The specifically disclosed application for the invention is a water level controlled planter. The fluid level control system includes a compartment in which fluid level is controlled. One or more removable plugs can be inserted in two or more fluid level control holes at different levels in the compartment. An air lock prevents air from flowing into the reservoir when the water level within the compartment is above the fluid level control hole. When the water level in the compartment falls below the uppermost open fluid level control hole, air is permitted to enter the reservoir and water may flow through the fluid level control hole into the compartment.
