my greenhouse

A quick tour of the greenhouse I built last fall. I am in the Black Hills of South Dakota zone 5. It collects heat, but I need to improve the insulation so it holds on to the heat better. The seedlings growing were all direct seeded to the greenhouse the end of Feb. I hope to be able to grow greens all winter. I did not get it finished until this last Nov so I was not able to get anything growing for the this last year.
