hello Chip -40 we are at 12 at the moment, that is killing me, just came in from cleaning horse pens. Subartic good name for zone 3.I just read your post again that is impressive. Good morning Karen I like 60F the idea of sitting out there in the winter sounds good. I think I will only need heat at night facing south it may get to hot in the day. I am putting in a small swamp cooler with fans .This greenhouse is on my bucket list so I would like to do it right first time. I wonder what the most popular plants people are growing in hobby greenhouses?
