Abstract: A device for propagating beansprouts or other plants has a container for the beansprouts. One side of the container is substantially covered by a supporting plate which may be in the form of a disc perforated with many tiny holes. A shaft is carried by the supporting plate and extends within a center tube mounted within a water tank. The tube is preferably triangular and has three faces provided with a plurality of spaced-apart holes. The spacing between adjacent holes is greater towards the bottom of the tube. A plurality of small resilient stoppers are lodged within the respective holes in the tube. The growing strength of the beansprouts pushes the supporting plate (upwardly in a preferred embodiment). The shaft, which is carried by the plate, moves within the tube.
