Bean sprouts can be easily grown at home using mung beans. Here are the steps to seed bean sprouts:

1. Rinse the mung beans thoroughly and soak them in water overnight or for at least 8 hours.
2. After the soaking period, drain the water and rinse the beans again.
3. Place the beans in a glass jar or a container with a lid. Make sure the container is clean and has enough space for the beans to grow.
4. Cover the container with a lid or a piece of cloth to prevent dust or insects from getting in, but still allow air to circulate.
5. Place the container in a warm and dark place, such as a cupboard or a pantry.
6. Rinse the beans with water two to three times a day, making sure to drain the water thoroughly each time.
7. After two to four days, the sprouts should be ready to harvest. Rinse them with water one last time and remove any remaining bean skins or roots.
8. Store the bean sprouts in the refrigerator and consume within a few days.

Note: Always make sure to wash your hands thoroughly before handling the beans or the sprouts to prevent contamination.
