Vertical farms bring locally grown produce to supermarket shelves

"We grow from seed to finished product, to edible crop, so it comes in as a seed, and with most plants, we would like to start with germination, so germination happens here in the facility. Then after germination, it goes to our nursery, and then in our nursery, the plant matures under the right conditions to become strong enough, big enough to be transplanted, so once it's from the nursery, it goes to our gutter system," says Laurens Post, a plant scientist at SweGreen in Stockholm, Sweden.
