Mission Endure 52: Passive Solar Greenhouses

I found a wonderful, short 3 -minute video by Rob Avis, of Verge Permaculture, showing his small passive solar greenhouse in Calgary, Alberta. The video is titled, 200 sqft Backyard Passive Solar Greenhouse. Rob is an Engineer and has done a lot of work analyzing and planning passive solar greenhouse builds. It is well worth the time to watch his videos
