I am having trouble maintaining70%RH in my humi. It is relatively new, so I do not think that there is a problem with it. I have inspected it and it looks fine. I cannot seem to get the RH above 67% though unless I turn the lamp on that sits next to it. If I turn on the lamp (which gives off quite a bit of heat) then my humidor will climb up to 70 ot 72%. Does this sound weird? I cannot figure it out and I do not want to keep raising and lowering the humidity level. Any suggestions would be appreciated.

67% RH is good. But your hygrometer could easily be of by 3%. Stop messing with it.

67% is fine. Don't worry about it so much 😉

Thanks, I was just becoming concerned because I was always maintaining 70% previously. I live about 15 miles outside of Cleveland so it is cold here.I read some things on a message board about dry air from the furnace dropping the humidity, maybe that is it?

I find 67% to be the best, at least for my tastes. Not too moist, not too dry. 70% is just a nice round number that's easy to remember and target. Interesting about how the lamp affects the humidity.

I PREFER mine to be in the 63-68 range ... so from where I sit, you're pretty much spot-on ... (plus, as mentioned above, your hygrometer could easily be off a couple of points) ... don't worry too much ... after all, they're just dead leaves ...
