Nemo's Garden

"Just off the coast of Noli, Italy, tethered twenty feet below the surface of the Mediterranean Sea, hover five bulbous biospheres filled with plants, light, and warm, wet air.
The underwater greenhouses make up Nemo’s Garden, an experimental agricultural project, now in its fourth year, operated by a company that specializes in diving equipment."

Man what the fuck. What even.  No sooner than I'd finished greenhab, some Italians are doing the exact same thing but way bigger and better. Their reasoning for growing terrestrial plants underwater is much the same as mine:

"The balloon-like biospheres take advantage of the sea’s natural properties to grow plants. The underwater temperatures are constant, and the shape of the greenhouses allows for water to constantly evaporate and replenish the plants. What’s more, the high amounts of carbon dioxide act like steroids for the plants, making them grow at very rapid rates.
Ocean Reef Group — a diving equipment company — is monitoring five balloon-like biospheres that house a number of plants, such as basil, lettuce, strawberries and beans. The group has a patent on the structure and plans to build a few more to experiment with other crops, such as mushrooms, which should thrive in the humid environment.

Sergio Gamberini, president of Ocean Reef Group, came up with the “crazy” idea of growing plants under the sea while on a summer vacation in Italy. He immediately made a few calls and started experimenting, sinking the transparent biospheres under the ocean and filling them with air."

Their habitat design is the same one I had in mind for Hamlantis (right). Easy to emplace as you only fill them with air once they're already down there and secured, you can use buckets of sand from the seafloor as ballast, and you can get inside from the waist up to clean cages and resupply food/water.

Update: Check out the livestream here and literally sit around watching plants grow


  1. so does this mean the hamsters will get bigger? If so you've got a fair market there yourself so don't be upset.

  2. That's great news actually. This means they have already spent a lot of resources and scaled up, so you can learn from their designs (as you have allude to in your comparison to Hamlantis). I would learn from their design choices and continue to move forward with your idea, let your science progress.
