After washing, soak the beans in tap water at room temperature for eight hours. In the cool season, use warm water (32ºC) for soaking.

Put the soaked beans in containers. Do not fill the containers to more than 75% of their capacity to avoid overflowing when the seeds sprout.

Apply a fine water spray or mist uniformly over the seeds at 3-4 hour intervals during the hot season and 6-7 hours during the cool season. Apply just enough water to keep the sprouts continuously moist without drying.

An overhead water pipe line fitted with taps and movable water pipe or an automatic sprinkler system connected to a timer is very convenient for watering.
