Agreed! It's probably a combination. Factual or not, I can "see" a
scenario in which the low RH increases the resistance, while lack of osmotic
pressure within the plant does not give it sufficient force to overcome it.

I am enjoying everyone's humidity cause.
I am like Wendy - plenty of humidity (75-80% most of the time)
but I have had it happen. So humidity maybe a large cause but it
