I would estimate I'm running about 5 - 10 degrees below that. I'm center basement next to the furnace which is the warmest place in the basement. I'm still putting up walls, once I get them and the panda wrap up things should warm right up. I was going to do that today, but I hung out with my boy's instead. Now I'm on another planet so tonight is done. At least I have my priorities in check.
Oh, back on topic, got a programmable space heater if I need it.
I've read that temperatures closer to tropic conditions work best.

Thank's for the info.
