One of the more interesting things at Epcot is the Living With the Land boat tour of the experimental greenhouses. Here you can see all kinds of ways to grow fruits, vegetables, herbs, and flowers without soil. What really surprised me is that a lot of the restaurants in Epcot, particularly the ones in The Land complex, use the produce from these greenhouses!
Growing fruits and vegetables on a trellis like this gives the plants more air, which reduces disease and pest problems. This is one idea you can try at home pretty easily!
Examples of aeroponics. Water and nutrients are applied directly to the roots.
Plants for space research! How cool is that? Ideally, some day the astronauts on the Space Station will be able to grow their own food.
Since I wasn't taking notes, I had intended to do some reading up to supplement these pictures. I quickly realized that I would be getting most of my information about the Epcot Experimental Greenhouse from this post at Inhabitat, particularly because Jill had a chance to do the Behind the Seeds tour, and I did not. So instead I invite you to head over there for more pictures and detailed information about the pros and cons of what Disney is doing here. It's very interesting!
