Guitars are often produced at what is considered to be average. The question is: what is the average household, the average of the guitars environment?
Generally speaking your guitar is comprised of organic material, and may be best kept in the room in which you are happiest, that is in the absence of you owning and understanding a device which will measure RH or relative humidity: Not too hot or wet, or too dry. Cole Clark Guitars manufacturing is centred on 43% Relative Humidity. Cole Clark does not provide a warrantee against prolonged exposure to extremes of humidity or temperature. If your guitars action is high, it may be that the neck has pulled forward given the compressive force of around 70kg, at concert pitch, exerted by the strings, or that the face has taken on moisture, causing the top or soundboard to convex, which may cause the action height to increase. A slightly lower and higher saddle in your kit is an advantage. We use and recommend Graphtech BQ 9200 for our six string acoustic guitars.
