Either way, check out the photos, they have lots of little captions and deserve a gander. The green house is the star, I built it from plate glass collected from the local dump. They were very kind saving it for me as it came in. The wood came from various benefactors, leftover Reno supplies mostly. The 4 corner posts were from an old play set we had in the backyard when we bought the house. Windows and doors came from the dump as well. The floor is 2'x2' concrete paving stones, these came after I had built the greenhouse, ironically they fit the floor perfectly like I had it planned to begin with! The light is awesome, I really should take a picture of it at night.
We grow all sorts of things not normally possible so far north, tobacco, bamboo, tomatillos and the like. Of course all the regular things grow just fine here with out a green house like tomatoes, basil, peas and carrots for the kids to snack on through the summer. This year I have germinated coffee beans, who knows in 4-5 years I could be drinking coffee from the greenhouse!
