There are many varieties of sprouts, and there are dozens of varieties that can be planted at present. Like the familiar soybean sprouts and mung bean sprouts, it is also one of the varieties of sprouts. Besides soybean sprouts and mung bean sprouts, there are pea seedlings, radish seedlings, Toona sinensis seedlings, peanut bud and black bean sprouts. These varieties have a certain share in various markets. In addition to commercial large-scale planting, family users can also grow their own vegetables at home, and hydroponics is a relatively simple and convenient planting in the family.

Seedling vegetables do not need soil and fertilizer, they grow by the nutrition of seeds themselves. The cycle is shorter than that of traditional fields, and it can grow in about seven days under suitable temperature conditions. The water for hydroponics of sprouts is ordinary tap water or well water. The relatively simple varieties of sprouts are pea sprouts, soybean sprouts, mung bean sprouts, radish sprouts, black bean sprouts and peanut bud. Many people think that Toona sinensis seedlings are not easy to grow, but the method is wrong, and hydroponic Toona sinensis seedlings are also relatively simple.

Seed soaking: Except warm water in winter, seeds are soaked in cold water in other seasons. Seed soaking time is 10- 12 hours in winter, 8- 10 hours in spring and autumn, and 6-8 hours in summer. The specific time depends on whether the seeds swell. For example, the seeds of peanuts, radishes and wheat skins need to be soaked for 3-6 hours. The shell thickness of water spinach, buckwheat and broad bean takes a long time, and the soaking time of seeds at high temperature should be short rather than long. After a long time, the growth will weaken, vegetables will rot easily and the yield will be low. After the seeds are soaked, peanuts should germinate, and other buds should be put directly without germination. After the vegetables are put away, spray water on the seeds every day to keep them moist. Bean sprouts need to be drenched with water, and the water must be drenched. Most seeds generally germinate within one day (the germination of Toona sinensis is 3-5 days slower), and then the water is continuously sprayed every day to make the bud tip grow into chassis water (the root is the root after the bud tip grows). After the bud tip enters the water, continue to spray water on the vegetables every day. If you don't have time, you can spray water in the morning and evening, and the vegetables sprayed every day will grow more tender.

Hydroponics is to let the roots of vegetables grow into water, instead of soaking the whole vegetables in water. Many friends who haven't hydroponically cultivated sprouts think that hydroponics is a vegetable grown by soaking seeds in water, which is extremely wrong. Always keep the seeds moist after they are put on the plate, but don't soak them in water directly. If seeds are soaked in water or vegetables, they will rot. The wat in that lower wat receiving chassis is lower than that in the upper planting tray, and the root grow in the water.
