The present Invention is a device (99) Plant cultivation which is provided with a Tank (19) of crop that is to grow a plant with a Water Tank (30),(56) and a part of Heat Collection. The Water supplied by a Water Tank 30 crop cultivation through the Tank 19 38 through Irrigation.The Water Tank 30 also sucks the Culture Water Tank through a Pipe 19 cultivation 3 6 Water Suction.(56) the part of Heat Collection part (57) which has an air Storage Tank is communicated with an upper section (30) of water.(56) the part of Heat Collection solar receives Light (93)And the pressure of heated air into the Air Storage (57) on the surface of the water in the Water Tank (30).(30) the Tank Water Supplies Water of cultivation has been pressed by air to a material (90) of Culture medium, which is arranged inside the cultivation Tank (19),The above through the irrigation (38).The part (56) raises the heat Collection surface of the water inside the Water Tank (30) as a result of hot air is cooled by a reduction in solar light (93).The Water Suction Tank (30) of the Culture Water of a Tank Bottom section (20) (19) of culture through the Suction pipe (36) of water according to the Culture Water risesLa presente invencion es un dispositivo (99) de cultivo de plantas que se proporciona con un tanque (19) de cultivo que es para hacer crecer una planta, con un tanque (30) de agua, y con una parte (56) de recoleccion de calor. El tanque 30 de agua suministra un agua de cultivo al tanque 19 de cultivo mediante un conducto 38 de riego. El tanque 30 de agua tambien succiona el agua de cultivo del tanque 19 de cultivo mediante una tuberia 3 6 de succion de agua. La parte (56) de recoleccion de calor que tiene una parte (57) de almacenamiento de aire comunica con una seccion superior del tanque (30) de agua. La parte (56) de recoleccion de calor recibe luz (93) solar, y la presion de aire que se calienta dentro de la parte (57) de almacenamiento de aire presiona la superficie del agua dentro del
