How are your cigars smoking?
Are they spongy and hard to draw? Any signs of mold? Dry as a bone and crack when handled?
Or are they smoking okay and looking good?
Hygrometers are nice, but don't get into a position where you can't see the forest for the trees. What's important is how your cigars smoke and their condition.
I have four or five hygrometers, none of which I've paid any attention to in years. My cigars tell me what condition they're in, and I make adjustments based on that. Watching the numbers is good as you're gaining experience, but try to listen to your cigars as well. They'll tell you the true story.
