Eric, if this is what you’re talking about, and I assume it is, here is what I found online. I live near Cincinnati, Ohio so it’s between 14.5 and 12.2 I might move them anyway. At the very least put a thermometer close to them and keep a check on the temperature when I have the heater running. I wouldn’t think it would warm it up to much because of the sheds size. After all the work that went into getting them I’d hate to ruin them before I had the chance to do it with with a draw knife and a rasp.
