This is my cool greenhouse that is soon to be replaced. And the new one will definitely have a taller roof with more slope and the misting tube under a bench. It has a minimum night temperature of 50°F and a maximum of 75°F except on the very hottest days when it can go to 85°F. It was built in 2 parts. The first was a 10 x 12' section attached to my workshop to the north and a small shed to the south. Then a 9' x 17' extension was added on to form an L shape. It's a bit hard to get the sense in images, but this will give you an idea. The first four images are of the 10 x 12 section with the last of these images looking from the door of my workshop to the far corner of the L. The rest of this section extends around the corner to the right and those are shown in the next thread.
