Abstract: The Garden Waterbed is constructed of a durable tube of flexible UV protected material. The ends of the tube have been sealed, enabling it to hold water. Circular holes have been cut out and sealed down the center length of the tube, at regular intervals. A valve is installed at one end of the tube, allowing water to be filled into the large single chamber and hold it with a tight seal. There are multiple purposes of the Garden Waterbed. The water bed's intended use is; to be rolled out in a agriculture environment or garden area, to be filled with water, and to have plants buried in the soil within the growth units. The surrounding water increases the thermal mass surrounding the plants in the circular holes. The thermal mass absorbs the suns energy and increases soil temperature, thus increasing the growing season and boosting production. The opaque plastic stops sunlight from reaching the ground and eliminates weeds and undesirables from competing with your crop.
