It is a plsatic biosphere that rest between 15 and 36 feet below the ocean's surface and hold about 528 gallons of air. It provides a water-conserving, overall sustainable alternative to on-land agricultural operations, particularly helping dry coastal nations grow more food without having to desalinate more water — a costly and resource-intensive process. The plants require just a small bit of starter water, but from there, they're self-sustaining. Sunlight heats the submerged spheres, which contain humid air that naturally condenses into freshwater on the walls and drips back into the soil.

Nemo's Garden is not only a technological endeavor, aimed at making underwater farming an economically viable, long-term alternative form of agriculture, but most and foremost it is an eco-friendly and self-sustainable project. The use of renewable energy harnessed from the sun and of fresh water obtained by desalination of seawater, in fact, make Nemo's Garden a self-sustainable system. The microclimate and thermal conditions within the biospheres are optimal for plant growth and crop yields, not unlike a conventional greenhouse, yet it requires no additional energy sources. The underwater farm determines very minimal, if none, interaction with the marine environment and related ecosystems, exception made for a positive shelter-like effect in order to support the repopulation for the surrounding marine areas.

The project’s goal was initially a provocation, but suddenly turned in something more ambitious: create an alternative system of agriculture, especially dedicated to those areas where environmental conditions, economical or morphologic reasons make plants growth extremely dif?cult. Nemo’s Garden’s aims to create a system that utilizes natural resources already available, the foremost important one being the oceans and other bodies of water.
