I get a lot of questions and pictures of sprouts where people are concerned that their sprouts are moldy. Here's the key to figuring it out - USE YOUR NOSE! If your sprouts smell bad - DO NOT EAT THEM! However, a lot of the times what you think is mold are these tiny little white fibers coming from the roots telling you that your sprouts are thirsty. Once you give them a good rinse you should see these hairs disappear almost immediately. MAKE SURE TO RINSE YOUR SPROUTS AT LEAST TWICE A DAY, SPROUTS GET THIRSTY TOO!
