RH 65% or 70%

[dHUTCH]

I like to keep mine 65ish tending a little over...

when I kept em at 70 I seemed to have my cigars split while Iwas smoking them and they tended to go out more and I'd have to relight a half dozen times.

What do you mean by split? As in the wrapper got a crack in it and would start to peal back? This is not caused by higher RH; in fact the higher the RH the less likely a leaf is to crack. Think of leaves on the ground. A dried up non wet leaf will crumble easier than a non-dried up leaf.
