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. Projections on the shaft engage the respective stoppers, sequentially dislodging the stoppers, and allowing water to enter through the holes, into the tube, and to pass through the tiny holes in the supporting plate to sprinkle over the beansprouts. As a result, the growing strength of the beansprouts controls the flow of water thereto.
