  • Patent number: 8011134
    Abstract: A method of creating a hydroponic growing medium. The method includes retrieving polyurethane constituents and mixing the polyurethane constituents in a shear spray mix, creating a resultant foam. Thereafter the resultant foam is placed in a form to cure and a forced heated air is convected in a post-processing step, whereby the hot air convected upon the resultant foam causes additional cracks throughout cell walls within the resultant foam. These fissure cracks allow for a wicking action to occur in the foam, making the material suitable for a hydroponic growing medium.
