We grow mung bean and alfalfa sprouts at home. My mung beans sprout great, but the texture is a little tougher than store bought sprouts. I've experimented with growing them in the dark, or on the counter where they see a little bit of sun. This turned into Penn's science experiment: Mung Bean Sprouts vs. Light and Dark. He discovered that they grow TWICE as fast in the dark!
He was disappointed that he did not place this year. But I'm glad that's an achievement he desires.
