I think so too Ray. It does seem to pop up this time of year. In the winter humidity is easy to control. With the humidifier on the furnace I can maintain 60-70%. When the AC is on this time of year it can get as low as 20% and there is not much can be done. I have net pots filled with wet sphagnum in some areas but the AC will work harder if more are added.
