  • Patent number: 4315381
    Abstract: An automatic hydroponic garden includes a single container for water and growing medium immersed in the water. A means is provided in the container for constantly mixing the water and air and circulating the mixture within the container. An enclosure surrounds the mixing means, into which plant nutrient may be added to the water and which disperses the air-water mixture in the container. A means for supplying air is connected to the mixing means. The result is an improved hydroponic gardening method in which plant roots are immersed in the water, which is both constantly aerated and circulated in a manner that does not agitate the plant roots.
