This is a home-use soilless hydroponic bean sprout growing kit featuring a modular, tiered design. It consists of a yellow outer box, a white inner tray, a fine-mesh sieve, and an annular flow-directing plate. Its integrated structure for water storage, drainage, and light shielding enables soilless cultivation of bean sprouts. The water-storage base provides a stable water supply, while the perforated seedling tray prevents bean sprouts from leaking out yet allows their root systems to freely absorb water. The flow-directing plate optimizes water circulation, and the outer box serves both as a light shield and a moisture-retaining barrier, inhibiting photosynthesis to prevent the sprouts from turning green and developing a bitter taste. Throughout the entire process, no additional liners or frequent watering are required, making operation simple and hygienic. This kit makes it easy to grow sprouts such as soybean sprouts and mung bean sprouts at home—safe, controllable, and reassuring to eat.
