This is my first post on this forum. I discovered the forum from a youtube vid when I was searching for a way to heat my greenhouse. I live in Southeast Idaho about 70 miles south of West Yellowstone. We get days that will be -20 with highs in single digits. Anyways, here is what my greenhouse is looking like. I am a wood dealer and I sale a lot of cedar products so I wanted to do a greenhouse out of cedar. I framed my GH out of 2x6 Port Orford Cedar. If you don't know what Port Orford is just google it. Its a hard wood that grows on the Oregon coast and it has a high oil content to keep it from decaying. I got windows from a guy on craigslist to put all the way around the outside. This week I will finish the roof structure and get the windows installed. Can't wait to get it up and running.
