Abstract
Hydroponic gardening apparatus mounted within its own shelter includes a lower reservoir containing a liquid nutrient, and a pump for flowing liquid nutrient from the lower reservoir to an upper reservoir. At least one feed conduit inclined downwardly away from the upper reservoir and connected in fluid communication with the interior of the upper reservoir guides under the force of gravity liquid nutrient from the upper reservoir to a container having growing media disposed in the interior thereof adapted to support and to nourish plants therein. The container is inclined downwardly toward the lower reservoir, and a return conduit is connected in fluid communication with the container for guiding liquid nutrient therefrom back to the lower container for recycling purposes. The hydroponic gardening apparatus is mounted within the interior of a shelter, and the container and conduits are mounted on support posts for the transparent roof of the shelter.
