Abstract: A method for integrating at least one very high output (VHO) fluorescent lamp and at least one ballast within at least one fluorescent lamp fixture sealed from the growing environment is disclosed. The at least one ballast is secured within an upper fixture structure between a first cooling duct and a second cooling duct. At least one mid-plate reflector is mounted within the at least one upper fixture structure enclosing the at least one ballast thereby defining an upper chamber and a lower chamber. The at least one fluorescent lamp is installed in the lower chamber that is sealed from the growing environment by a transparent glass sheet, mounted to either or both the endplates or upper fixture structure. At least one fan is installed to the first cooling duct or the second cooling duct to provide the forced air cooling.

Abstract: A horticulture light system comprising a housing, glass retention rails, gasket, glass sheet, and threaded fasteners. The housing constructed of no more than three portions of sheet metal, defining an interior space therein and having an open end towards the plants, the housing interior space constructed and arranged for containing a grow lamp and reflector to project a pattern of light out the open end of the housing at the plants, the open end including a rectangular sealing face for mating with the gasket, the gasket sealing the glass surface to the rectangular sealing face when compressed by the glass retention rails. The glass retention rails also constructed from sheet metal, easily formed into a L shape, attached by common threaded screws, and as tightened, compressively secure the glass to the gasket and housing. Loosening the threaded screws removes the compressive force, unsealing the glass from the housing, making for easy glass removal, facilitating maintenance and cleaning.

Abstract: A method of constructing a clean room utility pouch includes cutting dust-proof fabric in accordance with a pattern. The cut edges of the dust proof fabric are treated to eliminate loose particulates or loose fibers along the cut edges. Piping can be secured over the cut edges instead of treating, or in addition to treating the cut edges, and finished by securing the pieces together to form the utility pouch. In some embodiments, a mesh is secured to the cut edges to form a portion of the utility pouch. Air can then flow into and out of the pouch via a pouch opening and the mesh.

Abstract: A horticultural light system integrating a grow lamp and lamp ballast within a single fixture. The grow lamp is enclosed by the lower exterior structure and benefits from cooling atmosphere that is forced through the lower exterior structure to regulate the grow lamp temperature. The lamp ballast is mounted to a ballast plate above the lower exterior structure. The ballast plate shields the lamp ballast from the heated atmosphere as it rises off the top of the lower exterior structure. Stand offs or other separation means keep the ballast plate at a distance from the top of the lower exterior structure to create an air gap that thermally isolates the lamp ballast from the heat generated by the grow lamp, thereby increasing the reliability and life of the lamp ballast.

Abstract: A biodegradable absorbent mat for absorbing and containing moisture including debris from pet feet, consisting of a bottom layer formed of an organic absorbent mesh composite, a top layer affixed and overlying said bottom layer, having an alternating combination of stitched paper ruffles and helically intertwined brush fibers. The organic mesh composite may be burlap or paper, treated with starch for rigidity, and then coated with a natural gum or latex to enhance friction grip and provide a moisture barrier. The configuration of the stitched paper ruffles, provide maximum exposure of the cut linear edges of the ruffles to a pet's feet. The cut linear edges wick away moisture increasing the rate of absorbency. The stitched paper ruffles provide increased capacity for absorbency and debris containment. The helically intertwined brush fibers primarily remove debris from pet feet, and also provide a secondary function of containment of debris.
