ABSTRACT:
A system and apparatus for growing plants in a nutrient solution while supported in an inert medium contained in a pot container includes a nutrient solution reservoir and automatic feeder apparatus for maintaining a predetermined level of nutrient solution in the container including a tube member connected to the reservoir having an open end carried a predetermined distance above the container bottom for dispensing the solution. An air vent communicates with the tube member allowing air to enter the reservoir in response to the level of nutrient solution in the container falling below the open end of the tube member as the solution is drawn by capillary action through the media into the roots. The nutrient solution flows into the container until the open end of the feeder tube is covered so as to continuously maintain the level of nutrient solution. An overflow opening drains excess liquid from the pot preventing overwatering and stagnation when used outdoors.
