Place the jar in a bowl that allows for the excess water to drain and place in a spot that receives that receives indirect sunlight. Twice a day rinse the seed/sprouts with water, swish, and drain.
I know that a while back there was and E.coli scare involving sprouts which lead to their unfortunate removal from my brother-and-I's beloved Carl's Jr. Chicken Club sandwich. But from what I've gathered—all will be well—as long as you take simple precautions to keep the sprouts cool and well drained. Happy Sprouting!
