A high tunnel that’s moveable would be an excellent project for an ambitious home gardener. Here’s a link to a series of videos and descriptions on constructing one of these devices. I note a properly supported/braced rebar tunnel would be equally easy to construct and it could be made a small or large as you like. Just don’t cover it during the winter or snowload will take it down. If you do leave it covered, be prepared to slash the plastic if you get a heavy snowfall. The weight of snow will quickly bend the hoops and twist it up. Here’s a link to the construction.
