Microgreens are young vegetable and herb seedlings harvested one to three weeks after sowing. They can be grown indoors on racks with trays, grow lights and a simple watering routine, so a spare room or a small rented space is enough to start.
Cafés, restaurants and premium grocers are the usual buyers, so speak to a few before you scale up and agree on regular weekly orders. Because you are selling food, plan for FSSAI registration. Yields and prices vary by crop and city, so run a small trial batch to learn your real costs.
