I have a remote weather monitor in it now, and it stays a constant 130F at 70% humidity. It makes checking the status without opening the barn much easier. Opening it lets all of the heat and humidity out.
I probably should have made it twice as large as it is, because it is already at maximum capacity, with only half of the Virginias harvested. Crap!!
I will paint the outside to Mrs. Cosmic's specs, which is to match the house, like the shed, barn, studio, and the greenhouse, which is a purple-tinted grey, with a green trim. Sigh, I know... she picked the colors. But, I will wait till all is cured before painting, with some sort of mildew resistant paint. But, I will consider just waxing the inside boards, to keep it non-toxic.
