Oh no. I reread the thread, and thought the lack of readings was odd. I am a bit of a house humidity junkie, as an asthmatic.
No attack at all - but date would have made it an easier discussion. 52% is good, and you inspired a conversation with my wife about whether we should do something similar as we we watch the readings. You provided inspiration, though we'll have to watch for a bit to see if the nitrat, I mean humidity goes up.
Sorry for the misunderstanding.
