THE POLYETHYLENE TENT
After seeing some of these polyethylene structures that Hugh Steavenson showed us, I am wondering what is meant by a polyethylene tent. In our situation we do not have any greenhouses as such, although polyethylene enclosures in a small measure serve as a substitute. We have had a little experience with juniper, yew and arborvitae, and quite a bit with broadleafs under what I would call a plastic tent.
