[CAUT] FW: Temperature/Humidity range

[Chris Solliday]

I'd like to revise my last reply to Alan, I'll stick with "will" because
here when the temperature rises around here in summer the humidity does
also. This does imply a rise in water vapor. I realize this is not what you
are addressing but it is what I was saying. I'll will try and be clearer
from herer. Nevertheless the site
http://ianrpubs.unl.edu/generalag/g828.htm#pc is very helpful and whether we
are concerned with pigpens or concert halls I think the info is well
presented. Chris Solliday
