Choose the place
The first step towards growing bean sprouts at home is to decide the appropriate place for placing the seed jar. A backyard is often the best place for plantation but make sure that sunlight reaches there and it is not too congested.
Arrange bean sprout seeds
You should visit a local nursery to arrange bean sprout seeds. Make sure that you buy the seeds of the highest quality as it will help you grow them better. Rinse the seeds nicely under running water.
Place the seeds in a mason jar
You can now place the seeds at the bottom of a mason jar before you cover them with 1 or 2 inches of water. The jar needs to be covered with a cheese cloth and secure it at the top of the jar using a rubber band. You should allow the seeds to soak overnight or for at least 12 hours.
Drain the seeds
Drain the seeds after the initial soak before you cover them with water once again. Swirl the seeds around the jar nicely before draining them again. Prop the jar up, after rinsing and draining, to ensure that it tilts with the opening downward. This process will help you prevent mold growth as all the water would be drained.
Continue to rinse and drain
You are now required to continue to rinse and drain twice a day at minimum until you get a sprout growth of about one to two inches. This process is likely to take three to five days, depending on the type of seed used.
