I have seen many Youtube videos of people growing mung bean sprouts, and they all pretty much look reddish brown. It's kind of unappetizing looking. The sprouts I purchase at Fry's Grocery are super white, no tails. They look so much better, and are much longer and thicker. I grow mine in a colander with weights, covered in the dark...Just as all videos mention. But, still why do they not look long and white as the ones purchased in the stores?
