Iran is leading the world in saffron cultivation, and to improve quality and reduce costs, agronomist Ardalan Ghilavizadeh is advocating for indoor cultivation. This method offers better quality, easier disease control, higher product density, and a reduced labor force. The team has found that an indoor 60-meter hall can accommodate 4 tonnes of saffron bulbs, yielding two kilograms of dried saffron per tonne. This means that the same saffron production space can be achieved indoors with only a fraction of the outdoor space.
