ABSTRACT:
Hydroponic aggregate is contained in a garden box in which plants are grown. Nutrient solution is supplied through a liquid tube from an airtight tank to an enclosed housing disposed beneath the aggregate on the floor of the box. Outlets are provided from the housing for discharging the solution to the aggregate. Air is supplied to the housing through an aeration tube. Flow of solution continues until a pool is built up on the box to a depth sufficient to submerge the lower end of the liquid tube. Air is then unable to flow up the liquid tube to displace the liquid within the tank and the liquid flow is thus stopped. A drain hose for draining off excessive liquid that may build up in the box serves alternatively as a liquid level gauge.
