1. Choose beans. Wash with clean water. When washing, be sure to remove all floating beans (mung beans, soybeans, peas). These are immature or spoiled beans, and their germination rates are extremely low.

2. In a tank, or a large plastic box, or other container (the material does not matter, as long as it is clean, the bottom can drain), lay a layer of clean sand about 5CM thick, wash it and soak it to expand. Spread the cracked beans evenly on the sand, not too many or they will break easily. Cover the beans with a layer of clean sand evenly, with a thickness of about 1CM.

3. Water. Water several times a day to maintain humidity but not allow water to stagnate. , Don't let the beans see the sun, otherwise they will turn green immediately. Covering it with sand will protect it from sunlight, or if you are concerned, cover the container with a lid.

4. Harvest. The bean sprouts will sprout out after a few days. Just wash away the sand in clean water. Bean sprouts grow relatively quickly, so harvest them in time!
