I have the air on 68 right now and my wife thinks that’s a little chilly.... I’d knock it down a few more notches if I could get away with it.
Heat in the winter is set somewhere between 62-64.
Home Depot was 50% off trees this weekend. Picked up a flowering cherry for 50 bucks and 2 good sized dwarf Alberta sources that are about 5 feet tall for 60 bucks a piece.
