I'll start by saying that I don't know. My assumption regarding soil chlorides is that it somehow increases the production of halogenated metabolites within the living leaf. If that's true, then the mineral content in the misting water of cured leaf should have little impact. If. If. If.Do you think the calcium carbonate/iron oxide from the hard water would have the same effect?
My experience with factory cigars is that some remain smoldering for a minute or more without puffing, but these seem to be rare. More commonly, a factory cigar will self-extinguish within 30 to 45 seconds.
Buy a jug of distilled water, and see if it makes any difference.
