First of all, it is best to use the new beans of the year, the germination potential is relatively strong. But no matter what kind of beans you choose, you should first wash them with water and remove all the floating beans, which are immature or have gone bad, and their germination rate is extremely low.

Secondly, choose the right container, pots, plates, tanks, large plastic boxes, casseroles, teapots or just cut a Coke bottle can also be used as a container. It doesn't matter what kind of container you use, it's clean, and it's best to drain the water at the bottom. There must not be oil in the vessel, or the beans will be spoiled.

Third, soak the washed beans overnight in boiling water until they swell and crack. Then change the water, put the beans flat in a leaky container, pay attention to as long as a thin layer can be, and then will be warm water wet paper towel over the beans (you can also use a towel or the like), to be covered all over, and then cover the lid, but can not be soaked in the water, otherwise it is either not out of the bud, or rotten buds. Then place something heavy on top to press down, the heavier the better, so that the bean sprouts are thicker. Be careful not to let the beans see the sun, otherwise they will immediately turn green.

Fourth, the container with beans in a warmer place, once a day to change the water (winter is best to use warm water, to not scalding prevail), the water should be evenly poured on the beans (without removing the towel) to repeat about two times. Then let the water slowly drain on its own until it is dry. The temperature should be balanced.

A few days later the bean sprouts will be arching out, and it is best when they are 5 - 6 centimeters long. Beans grow quickly after sprouting, so harvest them in a timely manner.
