LOL The hardest part would be keeping it cool in the summer!<<<
Not as difficult as you think, plant Thompson Seedless grape vines, train them inside to serve as shade, the leaves will fall in the winter and let the sun in, but keep it cool in the summer, have them a foot or more below the glass/roof and don’t ever cut them back, you will have a huge crop and a wonderful hiding spot for your escapes.
Or use the shade cloth or the lath, on the outside for shade.
Inside, leave dirt floors or maybe sandstone so you can wet it down.
The first summer we lived here, with a water style evaporative cooler on the roof, we almost roasted.
The second year the first attached greenhouse was up and by opening the door into it and allowing the moisture from the greenhouse to come in, it kept both areas cooler and nothing was changed on the cooler, simply more air circulating.
On the mountain, I used old sheets inside the greenhouse for shade on the west wall, during the summer.
Outside, you could plant something like gourds or winter squash and train it up to shade the greenhouse during the summer, or even corn and sunflowers.
LOL, you will find a way.
Thompson grapes won’t grow here! LOL The only type of grapes that will take our heat and humidity are scuppernongs, or muscadines. They are native to this area. Even the first explorers commented on them, saying they had never seen the like, not even in France. They have a unique flavor, sweet and reminiscent of wood smoke. The skins are tough so you hold them up to your mouth, squeeze hard, and squirt the pulp into your mouth. They are full of seeds, which most people spit out once they’ve sucked the sweetness out of the mass. Scuppernongs are amazingly good for you, and a beloved treat around here. The mother vine, as it’s called, is over 400 years old, in Elizabeth City, IIRC.
Now you’ve had your trivia/history lesson for the day! LOL
