I got a wild hair and decided to put up a tunnel greenhouse a couple of days ago. I bought a bunch of 20 foot lengths of plastic pipe (And don't think that isn't fun to haul across town in a Ford Bronco. Suffice it to say it was hanging out the side and back windows about 6 feet.) I stuck some pairs of rebar in the ground about 12 feet apart and pushed the ends of the pipe down over them to form a series of arches. This looked pretty good, so I got some plastic deck "lumber" and am now building a frame around the bottom with the pipe attached to it. (By the way, you can't attach a big slab of lumber to each end of a series of 20 foot plastic pipes and then easily flip the whole thing over. Trust me; I tried.)
