Remove any damaged seeds from the mix and discard them.
Place the good seeds in the jar and fill it with room-temperature water. Cover the jar using the cheesecloth and rubber band, and soak the seeds for 6 to 8 hours.
Drain the water out gently through the cheesecloth. The only water that should remain in the jar is the water that has adhered to the seeds. Set the jar aside overnight.
Continue rinsing and draining the seeds gently once in the morning and once evening so that they stay moist. After a few days, place the jar on a windowsill, which will expedite sprouting. Your sprouts will be ready in 3 to 5 days. If you have multiple jars sprouting at different stages you will have a constant supply of these energy- and nutrient-rich sprouts.
