No, these are not hatching pods for aliens....I have my strawberries under them! They are actually the coverings for old street lights. A friend of a friend had gotten them when the city they were from put in new street lamps, figuring they'd use them the way I am, as little green houses. But they never got around to it and they were given to me. They are so cool! A little fragile, and the shape makes them hard to cover a lot of stuff, but I just cover whatever plants are still sticking out with large plastic cups, the clearest I could find. We'll see how it works!
