all sounds a bit much to me, i just hung mine on clothes hangers and threw them in my wardrobe, and closed the door. (put the clothes in a different one first-don't wanna be going to work stinking of green). i had a fan on in the room pointed at the wardrobe and left the window open, kept the bedroom door closed. smell was not to bad, if your worried about it you just try to mask the smell with some air freshener or insence. my temps outside are very similar to yours . Bud dried in 3-5 days , no mold, no rot. keep it simple - things will go well.
but i guess it depends on how much bud you are drying. if you have loads, then hang it in your attic and get a few decent fans to blow the air around, open a window up there if you have one, and keep an eye on it, if you see any mold or rot then remove it as quickly as possible, and rethink!
