Still struggling with humidity spikes. Hurricane Matthew isn't helping. While not in path of Hurricane I am on fringe and getting a lot of rain which is forecasted to continue for a couple of days. I added a DIY rock salt dehumidifier that helps some. My problem is humidity spikes when lights are off (from mid-40's to mid-70's). I keep some fans going 24/7 but not all fans. Will humidity in mid 40's during "daylight" hours (12), with all fans running, dry out mold spores that might take root during "night" hours?
