Effect of evaporation on RH

    I hope it is ok to post a rather pedestrian question to those of you who may laugh.
    We own a vacation home in Phoenix and continually folks insist we should leave pails of water in the house while we're away to help raise the RH and keep construction materials from drying out, cracking etc.
    This seems to me silly considering the small amount of water which would evaporate into the enclosure of the house not even taking into account the air exchange constantly taking place with the outside air.
    If it matters, the house is 2050 sq. ft. with no basement and 10' ceilings.
    Please let me know if it is me who is out to lunch. Would you water your house while away?
    Thanks in advance for any and all input.

    What is the house made of? Too much humidity is bad as well.
    The effect of some open water will depend on many factors.
