In an embodiment of the method for hydroponic plant culture of the present invention, a hydroponic plant culture container is used which comprises an external container that holds water, and an internal container that is held inside the external container, is placed on and supported by the upper edge portion of the external container, and is filled with a growing medium with seeds sown on the upper surface side thereof These containers both are formed from a transparent or semitransparent synthetic resin. The internal container is a funnel-shaped container including a cup-shaped portion and a cylindrical portion extending downward from a central part of the bottom of this cup-shaped portion. The internal container is filled with a growing medium in a state in which a lower end of the cylindrical portion of the internal container is substantially in contact with a bottom face of the external container with a gap interposed therebetween, after which seeds are sown on the surface side of the growing medium, water is supplied through a watering port formed on one side of the cup-shaped portion of the internal container, so that water is supplied into the external container through a gap at the lower end of the cylindrical portion, and the water that has been supplied to and held in the external container is used to water the seeds sown in the internal container through the gap.
