The first step: take a small handful of soybeans, wash clean, the dried out, incomplete, moldy, this can not be born bean sprouts beans picked out. Then soak in water for 8-12 hours, the first soak is very important, to let the beans fully absorb water, rise. If you see the skin of the beans cracked, or there are already beans sprouting, it proves that the bean sprouts have been soaked.
Step 2: Take a clean mineral water bottle, cut it at the top 1/3, and using a knife or scissors, tie small holes all over the bottom of the bottle to make it easier to leak water. (You can tie the small holes bigger, beans can not leak out on it, so as to facilitate the later leakage.)
The third step: the soaked soybeans, respectively, into the two bottles, do not load too much, I soaked soybeans this time a little more. Put the bottom of the bottle pad a plate to prevent water. Because the whole process of bean sprouts can not see the light, so the bottle covered with a black opaque plastic bag, do not have to seal, as long as the cover shade can be. Put the plate in a humid and light-reflective place at about 20-25 degrees, a little warmer, and the bean sprouts will grow faster! In my house I put the bean sprouts close to the underfloor heating on/off valve.
Step 4: During the period of bean sprouts, drizzle water every 4-5 hours, and wait until the water is dry, then squat to the plate and cover with a plastic bag. Never forget to drizzle, if you do not drizzle for a long time, not only will not germinate, the beans will also become stinky.
