How to grow your own mung bean sprouts in a few days the same way mass producers of mung beans do it. This method helps you get long, straight mung beans.
Drill or punch drainage holes into the bottom of one of your plastic containers. You'll use this over and over again whenever you make sprouts.
Dump some beans into your perforated container. No more than what will cover half the bottom of your container. Start with 2-3 tablespoons. Place your perforated dish into one of the other tupperware-type containers and fill with water. Let soak overnight.
After soaking, drain the beans and rinse them. Remove water from the lower container and put the perforated dish back into it. Place your 3rd container on top of the beans so it's covering them up and touching them. Weigh the top container down with something heavy. Either fill it with water or set a heavy object on it.
Rinse and drain the beans every 12 hours. Be careful not to disturb the beans when you rinse and drain them. Keeping them in the same spot helps them grow long straight roots.
Rinse the beans one final time when they've grown big enough to your liking and refrigerate them. I like around 4 days growth for fat, juicy bean sprouts).
Notes

Follow my Alfalfa Sprout instructions, just use mung beans instead.How long can I store them? Close to a week if they're refrigerated.How can you tell when the bean sprouts are ready? You can eat them whenever you want! Even as early as day 2. They just won't be as big as they are at day 4 or 5.Are mung bean sprouts good for you? You bet! They're full of vitamins A, C and iron. PLUS an added bonus for vegans and vegetarians, they have more protein than almost any other plant. How can I use them? Put them in stir fry, soups or on salads.
