Nemo's Garden is a sustainable alternative system of agriculture for our future. Since its creation more than 40 different kind of plant have been tested for underwater farming from aromatic and fruit plants such as basil, tomatoes, strawberries to herbs used for medicinal purposes such as artemisia and tobacco. Here Emilio Mancuso, biologist who collaborate at the project, is seeding artemisia in hydroponic cones inside the biospheres.
