 @ed5703a4 @096e66c5 When you do get around to designing your greenhouse, plan to make it a Climate Battery greenhouse. It works very well for us here in Michigan and did not go below 45℉ (7℃) with little supplemental heat provided by an adjacent sauna. Also consider a pit greenhouse, if your soils drain well, or bermed if not. Ours didn't go below freezing last winter. https://duckduckgo.com/?q=climate+battery+greenhouse&atb=v375-1&ia=web

 @e73e808d @ed5703a4 @096e66c5 That is a fine example in Michigan. Figs, lemons, limes, ginger, turmeric. Thank you for sharing photos and a link.  It is inspirational. #Minnesota, #Zone4b.

 @ed5703a4 @096e66c5 I saw that vid about 15 years ago and it inspired our current system. 
 @e73e808d @096e66c5 can i ping you about your system when we're ready to move forward? 
 @ed5703a4 @096e66c5 Yes, you may. 
 @ed5703a4 @096e66c5 Another good source for info on these kinds of systems. Our #permaculture friend and colleague, Jerome Osentowski at Colorado Rocky Mountain Permaculture Institute, uses these kinds of greenhouses at 7000 ft. in Basalt CO and also offers design consultation. https://crmpi.org/

What polycarb did you use for the roof?
