You gotta love sprouts. They are the only food you can grow (sprout) in just a few days, plant a few of the sprouts to grow more and end up with a much large quantity of food than you started out with! Plus they are highly nutritious and taste good even to most people who are not veggie lovers.
You are right about planting the sprouts if the weather is so you can. The sprouts give the plants a jump start. I have sprouted beans to give then a head start when planting them.
