Karen, during the winter months, 2011, I had 90% of my plumeria stored in my (unheated garage) and in the attic, lying on top of my central-heat duct-work. I had a handful stored in the house, in a garbage bag in a closet. I lost 100% of those in the garage and attic. We were below freezing for three days here, with lows in the low-teens and highs in the low to mid-20's. I swore that would never happen again. All my plumeria are now in bags and in a closet.
My 400-500 orchid plants would probably all be dead by now if I did not keep the GH's at or above 55 F. My "orchid" GH usually stays at or above 60 as long as the outside temperature does not stay in the lower teens or upper single digits for too long. This has been a tough winter for me and my electric bills will show that.
Don't forget that I and others are waiting for a full description of where you get the shrink wrap, its specifications, and how you use it. Thanks.
