Ok folks, here is part 2 of Frank's Cuenca Weather Humidity and Mold Experiment. What has changed is it rained and so the humidity levels went up a bit. Even so, the humidity levels have been staying quite constant "in the house", whether its sunny out or if it is raining....and that is with several windows cracked open. We have noticed that the mold growth (in the house) still grows back but not as fast when the windows are left open during the day. This can be difficult to do when it is chilly outside. Stay tuned and follow along with this experiment to see what changes develop.
