Great posts. Thank you for sharing your build. It looks fabulous. I am also from NB, Fredericton area, and am reading your posts with much interest as I am in the research stages of building a greenhouse. I have a shipping container house and plan on a lean-to style on the south side on the container. Your culvert pipe was a great tip. Keep up the good work, and l am looking forward to hear what your temperatures are inside your greenhouse on these cold nights in February. Cheers
