Plant cultivation apparatus and method for growing crops in sequence

The method of successively growing plants and harvesting the crop output of said plants from at least two batches of seeds or seedlings comprising:

• providing a reservoir container, having a bottom, side and end walls and an open top exposed upwardly,
• placing a basket-style container within said reservoir container, said basket-style container having an open top and perforated side and bottom walls, and a means for assisting the transfer of water from said reservoir container to the interior of said basket-style container, said placing step including arrangement of the basket-style container so that the walls and bottom of the basket-style container are spaced inwardly from the walls and bottom of the said reservoir container,
• substantially filling the interior of said basket-style container and means of assisting transfer of water with a plant growing medium;
• locating into the upper portion of said growing medium a plurality of means for confining the roots of plants, said plurality comprising a first and second set of said means for confining the roots of plants,
• providing on the upper surface of said growing medium a source of fertilizer in an amount to provide 100% of the nutritional needs for the growth of said at least two batches,
• covering the top of the reservoir container and basket-style container with a cover sheet,
• cutting holes in said cover sheet at locations above respective said first set of means for confining the roots of plants,
• planting said first batch of seeds or seedlings through said respective holes into the growing medium without disturbing said source of fertilizer,
• adding water to the space formed between the bottom of the reservoir container and the inwardly-spaced bottom of said basket-style container, said watering step being repeated multiple times during the season of growth to maturity of said first batch of seeds or seedlings,
• harvesting the crop output of the plants grown from said first batch of seeds or seedlings before planting said second batch of seeds or seedlings,
• after harvesting the crop output of said first batch of seeds or seedlings, cutting holes in said cover sheet at locations above respective said second set of means for confining the roots of plants,
• planting said second batch of seeds or seedlings through said holes into the growing medium,
• adding water to the space formed between the bottom of the reservoir container and the inwardly-spaced bottom of said basket style container, said watering step being repeated multiple times during the time of growth of said second batch of seeds or seedlings to maturity, and
• harvesting the crop output of the plants grown from said second batch of seeds or seedlings.

A method of growing and harvesting the crop output from a first batch of seeds or seedlings followed by the growing and harvesting of the crop from a second batch of seeds or seedlings, said method comprising:

• providing a reservoir container,
• providing a perforated partition spaced above the bottom of said container,
• substantially filling the interior of said reservoir container above said perforated partition with a plant growing medium,
• locating into the upper portion of said growing medium a plurality of inverted cup-shaped barrier structures for confining the roots of plants,
• providing on the upper surface of said growing medium a source of fertilizer in an amount to provide substantially all of the needs of nitrogen and potassium for the growth of said batches during their respective growing seasons, said source being a layer of fertilizer adjacent to and coextensive with the upper surface of said growing medium,
• covering the filled reservoir container with a cover sheet,
• cutting holes in said cover sheet at locations laterally spaced from the locations of said plurality of structures,
• planting a first batch of seeds or seedlings through said holes into the growing medium without any substantial disturbance of said layer of fertilizer,
• adding water to the space formed between the reservoir container and said perforated partition, said watering step being repeated during the season of growth to maturity of said first batch of seeds or seedlings,
• harvesting the crop output of the plants grown from said first batch of seeds or seedlings,
• after harvesting the crop output of said first batch of seeds or seedlings, cutting holes in a cover sheet at the locations above respective said structures,
• planting said second batch of seeds or seedlings through said respective holes into the growing medium,
• adding water to the space formed between the reservoir container and said perforated partition, said watering step being repeated during the time of the growth of said second batch of seedlings to maturity, and
• harvesting the crop output of the plants grown from said second batch of seeds or seedlings.
