[0002] Hydroponics is a new type of soilless plant cultivation method, also known as nutrient solution cultivation. Its core is to directly immerse the roots of plants in nutrient solution, which can replace soil and provide plants with water, nutrients, oxygen and other growth factors, so that plants can grow normally. When planting bean sprouts hydroponically, first select healthy and plump seeds, soak the seeds in warm water for about 8-10 hours, prepare a double-sided tray, fill the bottom of the double-sided tray with clean water, then put paper on the upper tray, spray water to wet the paper, sprinkle the soaked beans on the tray, cover with cloth and place in a cool place to germinate, maintain a good temperature, change water and spray water regularly, and the bean sprouts will grow in about a week.

[0003] Because the culture water in the hydroponic box is not flowing and contains less oxygen, the bean sprouts often suffer from root rot and mildew, and the water quality deteriorates, affecting the subsequent cultivation of the bean sprouts. In addition, the traditional way of treating the culture water is to directly introduce it into the ground after use, resulting in a waste of water resources. In addition, the bean sprouts need to be watered regularly by humans, which takes up human resources. Utility Model Content
