Thanx for the advice! After the post was placed, I scanned Schulz (duh) section on conspics then did some research on annual temp ranges in Gifu Perfecture and found central China can be downright cold, similar to midwest temps.
So the conspics are parked at 50-53 right now and I sleep better knowing that others have used similar temps and they're a cold tolerant specie.
Thanx for the advice, much appreciated, and Happy Holidays to you...
