Abstract: Except for near visible light waves (about <340 nm), ultraviolet radiation (UV-B and part of UV-A) are harmful to all living organisms due to the destruction of DNA. The Hasegawa film (H-film) was developed through modification and chemical reaction on special film with europium (Eu); the H-film transforms UV-A radiation (300-350 nm) to a near peak photosynthetic active wave (600-650 nm). To understand how to use the H-film in horticulture efficiently, we applied it to crop production in greenhouse facilities. This report introduces the basic information on the H-film and its application for several crops during autumn and winter, when incident radiation is low. Therefore, we tested how to overcome this limited sunlight production environment by applying the H-film. We found tendencies for accelerated growth rates in Swiss chard (Beta vulgaris var. cicla) and spinach (Spinacia oleracea). As we expected, the growth acceleration was clearly observable through autumn and winter even with shorter daylight hours. Also, we will introduce our greenhouse facilities.
