Try a wood furnace, the outside is not hot, and you can run duct the entire length of your GH to spread the heat evenly by drilling a small hole every two feet in the top of the duct, you also must partly seal the end. I use these as back up in some GH's in case a natural gas heater fails in the early spring when we start our production.
