The process is super easy. You soak 2-3 tablespoons dried lentils overnight, then give them a rinse in the morning, cover your jar with cheesecloth or a nifty tea strainer as I did, then rinse about 4 more times throughout the day (every 4-5 hours). Do this for 4 days (by day three I had slowed down the rinsing to just 2 times) and badabing you got yourself some sprouts. Such fun.
