The garden is operated by volunteers and researchers. It runs on renewable energy from the sun, and irrigation water comes from condensation. This is made possible thanks to the relatively stable temperatures the sea provides.
Every year, Nemo’s Garden grew and expanded, and in 2016, they started hydroponics. This was also the first year the garden lasted through winter. They also established pressurized underwater labs and observatories in addition to the underwater greenhouses.
In 2018 the garden suffered a hit when sea levels rose, destroying everything. This was the biggest storm ever recorded in the Mediterranean Sea.
So how does this garden work? Several air-filled plastic pods are anchored to the bottom of the sea by ropes, chains, weights, and screws. A floating platform under each pod allows divers to stand firmly with their heads above water. Jump in for the video tour to see it for yourself:
