If your planning on doing carbon printing  ( a wonderful alt process)
you better get yourself a properly sized window air conditioning unit for
that room to maintain 70 degrees on a typical summer day for your area... A
Heating and Air conditioning contractor can do the calculations for you...
....... Your ideal   room  temperature is 70 degrees .. At 72 degrees the
gelatin takes a long time to set ( undesirable) and coating below 65degrees
is too quick setting and should be avoided.. I think some of the rational
B+W chemistry is close to that window .  Humidity control  for drying
carbon tissue is whole different issue ... ..
