Soak six soybean seeds in water overnight. Place them in a cup of room-temperature water.
Dump out the water that the seeds were soaking in. Rinse and drain the soybean seeds in a colander.
Place the seeds in a Mason jar or a glass. Wait for the seeds to begin sprouting. This may take a couple days.
Fill an 8-inch pot 2 inches from the top with soil.
Push each seed gently into the soil. Push the seeds 1 inch into the soil. Space each 2 inches apart.
