A commercial greenhouse roof and roof glazing system that maximizes the intake of direct winter sunlight while managing spring, summer and fill sunlight to similar levels so that continuous produce and other crops can be grown. This system has transparent corrugated roofing sheets with north and south facing sections running in an east/west direction, where portions of the outer face of the outer glazing sheet are coated, insulation separates each sheet at locations of top surface coating, gas spaces separate each sheet at locations of no coating, and reflective material coats the interior surface of the interior sheet at portions of insulation. This system has no moving parts other than the movement of the sun in relationship to the structure. The color of the sunlight spectrum is split in the summer months so that the photosynthetic active portion is maximized in summer months leaving the unwanted summer heat gain outside of the structure. Since all of the light is taken in through the root the walls can be of conventional architectural materials which allows the total growing facility to be placed at grade level or on the top floor of urban area buildings. This eliminates the need for much of the packing and fossil fuel-run distribution systems that typical growing facilities endure.
