Microgreens are harvested with scissors in less than a month following the germination. The baby plants are harvested when they are about 2-inches tall.
In comparison to sprouts, microgreens provide higher nutrition value and have more antioxidants. They are a great source of Vit A, B, C (ascorbic acid), E as well as iron.
All you need is adequate lighting (e.g., an indoor well-lit bench) and a tray or suitable container that is shallow, water, and the right growing medium.
