I haven't heated it, because it is very drafty, so night-time temperatures are the same as outside, but the hotter daytime temperatures made it possible for me to grow extra early crops of greens. Caulking would help. I'm currently harvesting tomatoes that were grown under floating row covers and cloches. I recommend the auto window openers. Best greenhouse accessory ever invented.
If I had a south facing hill, and a place to call my own, I'd definitely build the next one into a hill, or into the ground.
The door is poorly designed. I ended up bolting it to the frame during wind storms.

The only issue, is that one window pane blew off in a wind storm, one time. I screwed the glazing to the frame. The point I screwed into on the window panel was slender, so it ripped out. I added a better placed screw when I reattached it.
The roof as manufactured, does not shed snow. That was a problem for me, so I covered the gutter with a piece of sheet metal. I added a lot of caulking to better seal the glazing.
The door freezes during the winter. To free it up, I dump hot water on the bottom door runners. I screw one door shut during the winter, and added a latch between doors. Haven't had a door blow off since that modification.
One gutter was manufactured an inch short. So I had to munge that when I was putting it together. The second install went much quicker than the first.
The worst thing about the greenhouse, is that it acts as a catch-all for anything around the farm that I want to keep out of the rain.... My bad! No fault of the greenhouse.

Does anyone have suggestions for good quality grow lights? I have read that LEDs can be good, and I could eventually rig a solar panel for them because of their lower wattage demands. I also read the blue color is best for veggie growth (whereas red is better for flowering and budding plants).
