Preparation: Wash 1½ cups of dried mung beans and soak in cold water for 24 hours.
Setting Up the Planter: Place an onion pouch at the bottom of the planter for drainage, then line it with a paper towel.
Planting the Beans: Spread the soaked mung beans evenly over the paper towel in the planter.
Watering: Water the beans thoroughly every three hours, making sure the water drains well. Cover the planter with a black cloth to block light.
Harvesting: After 5-6 days, when the sprouts have grown 2-3 inches long, harvest by removing the sprouts from the planter. The bottom part can be trimmed off for easier handling.
