I have no advice regarding a portable greenhouse.
Every one I have seen pictures of seems like it would blow away in a strong wind. I hope someone else can advise you on that.
If I can borrow a friend with a pick-up truck at the right time of year, I want to make a temporary "greenhouse" just to use as a plant-starter. I have a rectangular piece of glass from an old coffee table, and I've been looking at these pictures...

Straw is fairly inexpensive here. I really like the look of the smaller six-bale construction. I'm thinking that since it rains a good bit in spring, I should be able to move them around once I plant the starts, and use the bales for straw-bale gardening. At the end of the season, I could spread them out and just let them rot into the ground over the winter.
Or, once I plant my starts, I could break them up and use them as mulch.
I
have heard that straw bales can be used for two summers, but I'd want to wait and see what they looked like at the end of the first summer.

In June 2013, we sent a winter gardening survey to thousands of readers all over the United States and beyond, asking growers about their best strategies for growing food in winter. This page includes a large sampling of the responses we received, organized by Growing Zone.
