The underwater sea farm that's like a space station

Nemo's Garden is a unique underwater farm for terrestrial plants where the gardeners need scuba diving suits. This novel experiment uses biospheres 10 metres under the water off Noli on the Italian Riviera, and was created to find sustainable ways of growing vegetables and herbs.

Food Unwrapped showed something similar about a couple of years ago, I think Matt Tebbutt presented it.

Would you eat a salad grown entirely underwater?

Intrigued to know where they get the fertilizer, be good if it comes from the sea too. The concept might be of interest to atolls under the impacts of climate change where water for farming and space on the atoll is at a premium. The lagoon could come into its own especially if the domes could be anchored at 2-3 m depth ie not need SCUBA but deep enough to avoid surface craft etc.

What are the production rates they got? That did not look like intensive cultivation and the plants did not look terribly productive. Most light is absorbed before 10 meters of depth. The basil looked horribly etiolated. Turbidity in the water would decrease that light rapidly, so building, tending and harvesting would have to be done with great care not to disturb the sea bed. Are those clear domes cleaned regularly or are they special antifouling surfaces? Because everything underwater gets covered with living organisms pretty quickly. I can imagine using a passive evaporation system for producing water in this way but using it in situ to grow plants seems unlikely to succeed.

If you turn water into oxygen to I flat a plastic dome then more area to grow then extend sun light into the dome or experimenting artificial sun with ionic flow intercept earth concentrating magnetic field by zoom technology can reduce harvest time down to fraction of traditional farm
