I was just wondering if anyone has used cattle pannels? They are a sronger welded wire pannel that comes in 4 X 15 or 16ft, I can't remember the exact length. I think they would be strong enough to be the hoops as well and support the plastic against wind. You could cut them in half and bend them over your raised bed. Just wondering, I've never tried it, but just thought about it. You can get them at your local farm supply type of store. The make really good trellises too.
