Georgia ain't on my mind - overwintering is on my mind. Idly, I decided to see what greenhouse kits were selling for, and WOW! They're hella spendy for being so flimsy. I was not impressed. Searching further, on the DIY greenhouse side, I found this article on solar greenhouses.
The idea is that you store up solar energy in the walls and floors that maintain a consistently warm temperature inside the greenhouse. It's sort of like adding a slab of stone to your oven to keep it consistently warm even when you open the door. Similar to an oven, a greenhouse can quickly get zapped of its warmth as soon as you open the door because the warmth is stored in the air.
Oddly, I was watching a Renovation Nation episode where the flipper installed a thermal wall which consisted of a lower section of wall made of glass on the outside of the house and cement blocks painted black on the inside. It was only on the lower portion of the wall for winters when the sun dips lower, and it was on the North side of the house. Pretty smart, right?
I figure I can build a lean-to solar greenhouse with attached shed and planters surrounding it to give it a cottage/non-shed/non-greenhouse look. Paint it white on the west facing portion and brown/black on the east facing portion to make it friendly for all seasons. Make the glass/Plexiglas removable. Make it small so as to not break any laws. Use cheap materials and spruce it up with paint and plants and veneer. Plant deciduous fruit trees just east of the structure for shade in the summer and sun in the winter.
