Take the mung bean in a bowl and clean it, making sure there are no stones. Wash them thoroughly 2-3 times. Soak them in fresh water overnight (for a minimum of 7-8 hours).
The next morning, discard all the water in which the mung bean was soaked. Rinse the soaked beans thoroughly.
Transfer the rinsed mung bean into a clean and dry container. Cover the container with a lid and place it in a dark and warm spot.
Rinse them every 24 hours. Make sure you handle the sprouts gently, as they are very delicate and can break easily.
Place them back in the dark spot immediately after rinsing them. The sprouts may turn bitter if they are exposed to light for a longer period of time.
Sprouted green moong will be ready in three to four days. Rinse them in a colander before storing them in the refrigerator.
Notes
Make sure you have cleaned the mung bean and removed any stones in it before soaking.
Use filtered water for soaking and rinsing the mung bean. If filtered water is unavailable, boil regular tap water and cool it completely before using it.
Place the soaked green moong in a dark spot for germination, like a cupboard near the oven. If you cannot find a warm, dark spot, place the container in a brown bag and place it in a warm spot.
When rinsing the sprouts, handle them gently as they tend to break easily. Place them in a colander to drain the excess water before placing them back for sprouting.
