Automatic sprouts culture bag

An automatic sprouts culture bag comprising a plurality of longitudinally arranged culture unit bags for storing sprout seeds, each culture unit bag being in communication with an adjacent culture bag by means of a siphon, the siphons being arranged in offset between adjoining longitudinal culture unit bags for siphoning suitable amounts of water from an upper culture unit bag into a lower culture unit bag forming an S-shaped flowing path and for submerging the sprout seeds, a siphon having a lesser diameter than that of a siphon above it, the plurality of longitudinal culture unit bags being hung on a lateral rod or wall for nursing sprouts in the air in conjunction with a water-dropping device arranged above said longituinal culture units bags for feeding water in drops from a water faucet to the sprout seeds through said longitudinal culture unit bags, the sprout seeds being received in an inner perforated bag in the logitudinal culture unit bag, and having an open free end folded in a Z-shape and pressed by a water bag filled with a suitable amount of water to permit sprouts to grow upwardly and freely.
