I ordered my first two rolls from "In The Swim" but went on eBay/Amazon for my second roll. There are lots of sources of solar blanket material and you can (perhaps) find a better deal going online. I also used this material to build a temporary GH along one wall in my garage. It is approximately 6'x10'x8' H and that's where I am over-wintering my potted plumeria (20) and cuttings (75) and some mounted staghorn ferns. I have one of those oil-filled heaters and "fired" it up last night when the temperature dropped to 31 F. I had the heater set at the lowest temperature and it kept the GH a toasty 75 F. I am going to replace that heater with a 4' base-panel heater, one that I can further reduce the heat output. I could not believe that oil-filled heater kept that space so warm. I just want to keep the temperature around 60 F for those plumeria.
