Substantially Circular Or Oval In Plan Patents (Class D11/152)
  • Patent number: 4173097
    Abstract: This invention relates in general to improved containers for the growth of plants which provide a better environment for the plant roots, and hence improved plant growth, by providing a better balance between the water and gaseous contents of the growing media. This is achieved through the use of indentations in the bottom and/or side(s) of the container, thereby, (1) increasing the surface area of the part of the container in contact with the growing media, (2) reducing the average distance a molecule must diffuse in the growing media from roots before encountering a media-air interface (and vice versa) and (3) reducing th proportion of relatively water saturated growing media in the container.
