Microgreens are young, edible greens harvested after the seedling stage usually within 7 to 21 days after germination. They are grown from various types of vegetables, herbs, or grain seeds and are typically 1 to 3 inches tall when harvested. Microgreens have a more intense flavor and higher nutrient content compared to their fully grown counterparts. They are certainly worth it to those who value their health and are careful about what they eat. Also those who are on vegetarian or vegan diets can enjoy these for their immense benefits. Overall these lean-mean-greens pack a heck of a punch to your diet.
