Giant vertical indoor hydroponic farm to start production

Denmark historically relied on importing foods like lettuce during winter. A new vertical indoor farm near Copenhagen, built by Nordic Harvest in partnership with Yes Health, aims to produce 1000 metric tons of greens annually. This facility, using hydroponics, could potentially meet Denmark's entire demand for greens. The farm employs advanced technologies like LED lights and nano bubble hydroponics to grow plants without soil or pesticides, using natural liquid microbial fertilizers instead of synthetic ones.
