Indoor saffron farming in a 20x20 ft room costs around ₹8.4 lakh to set up and uses hydroponics for year-round yield. With 40,000 corms, farmers can earn up to ₹60,000 in the first year. By second year, profits rise to ₹6 lakh as yields increase through corm multiplication, making it a smart, high-value agribusiness.
