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.
Claims8
A method of creating a hydroponic growing medium comprising:
- a. collecting polyurethane constituents and mixing the polyurethane constituents in a pour or spray process creating a mixed chemical composition,
- b. placing the mixed chemical composition in a form to cross link and react to create a resultant foam,
- c. curing the resultant foam and applying heat of at least 110° F. upon the resultant foam to have the resultant foam substantially maintain its shape,
- d. conducting post processing by convecting forced heated air of at least 200° F. whereby hot air is convected upon the resultant foam causing additional cracks throughout cell walls within the resultant foam,
- e. whereas the cracks throughout cell walls within the resultant foam are capable of wicking water therein, making the resultant foam conducive for a hydroponic growing medium.
