The air of the greenhouse stands at 79 degrees with humidity hovering around 83 percent. That’s a pretty good environment for a typical plant. But this is no ordinary greenhouse: It’s 20 feet under water, anchored to the floor of the sea just off the coast of Noli, Italy.
The experimental project is called Nemo’s Garden and is in its fourth year.
