Looking to build a 12x24x12 passive solar greenhouse and later turn it into a pit greenhouse.
I am in Zone 4a zip code 58854and have a few
How to set the footings to prevent frost heave and not twist the frame badly. Trying to save $$$
I am confused to the south facing angle, some sites say latitude plus 10. My latitude is 47, how do I set the walls on the south direction? More AM sun than PM?
How do I figure what angle is best for the glazing south side, the winter sun angle I think is 26 degrees, would like to avoid the summer sun as well.
Last, the goal is for all season gardening, right now it will be just extended season until I get the extra lighting and heating needed for all season.

Thank You in Advance.

Ron,

Good luck on your greenhouse.

I have some threads here on permies that might help you, also there is
a link to another site where there is a ton of solar information.
