Microgreens are nutrient-dense, flavorful crops harvested between the sprout and baby green stages and are well-suited for production in controlled environment agriculture (CEA) systems such as indoor vertical farms and greenhouses. This publication outlines key production practices, including environmental management (light, temperature, humidity, CO₂), system and substrate selection, irrigation, fertilization, sanitation, and integrated pest management. It also provides a sowing-to-harvest, market considerations, economic planning for commercial production, and at-home gardening applications. Microgreens offer rapid crop cycles, high nutritional value, and diverse culinary applications, presenting opportunities for profitable production in CEA.
