Joe,
Thanks! And actually I am. I did 95 percent of it by myself. Used a sledge hammer (turned upside down) to hold up railings until I could get a screw in it. It took from a couple of days after Memorial Day until now to get it almost finished - I need to add some screws here and there and probably find a way to anchor it in a few places, though I have plenty of wood, metal, blocks, etc., I tend to store and can put some of it on the base.
My next erection will be more challenging - a 12x16' greenhouse. It won't be a kit, though. I plan on using treated 4x4s for some of the posts. It will be 8' high on one side, 6' on the opposite. A door on the east side, a window on the west. Two layers of plastic - six mil inside, 12 mil reinforced on the outside. The north and west side will be solid walls (except for the window on the west) and very heavily insulated. I'm seriously considering lining the north wall with red plastic on the inside - supposedly it reflects red light back to the plants.
It's also a goal to make it self-sustaining during the winter and spring. Trim leaves from plants, add them to a big drum and have a continuous source of compost and compost tea.
