Might as well whore it up and reach 1000.....not bad for 2 and 1/2 years, eh?

At least I helped you break 1000 posts. Congrats!!

[EDIT] Does that make me a pimp?

[SIZE=3]DonnieW, If I understand what you are saying correctly you are talking about short term temperature swings, say less than 24 hrs. If so then I completely agree that you will see a flux in rh and the chart you provided should come pretty close predicting what these changes will be. I also agree that these changes are nothing to fret about and you would run your self crazy trying to compensate for them. More or less just some thing to be aware of. On the other hand I also see and agree (and it looks like you do to) with what the others are saying in terms of long term stabile temperature and the fact that there is no need for any sort of humidity compensation no mater what temp you keep your smokes at. It would be great if we all could keep our cigars under laboratory conditions and rock solid temperatures but unfortunately that is not the case and some will have to store there cigars in a place that sees somewhat rapid temperature change and with that change will come a change in the indicated relative humidity because the amount of moisture in the air remains pretty much the same. I may be wrong but this looks like more of a misunderstanding than a disagreement. The important part is at the end of the day we still have some great cigars to enjoy and great company to enjoy them with!

I've seen this conversation pop up several times during my brief membership here and it makes my head hurt every time. The thing I take out, it for what it's worth is what we are looking for is "Moisture Content" The way we measure that content is with a device that measures relative humidity in the surrounding air. This device reads differently depending on the air temperature it's in. Without starting a whole new debate, the common setting most of us see is 70/70. If that's correct then there is a specific amount of water in the cigar at that point. In a controlled environment we could assume that X amount of water is present at that point. If we changed only the temperature, the reading on our device would change but the amount of water would not. Assuming that is correct. The changes we see in our everyday storage solutions need to take that into account. I think the biggest problem new smokers find is the need to maintain a specific RH at no matter what temperature they have. Thus the numerous threads on people struggling to maintain a specify RH all the time. If you find that your stuff smokes best at 65 and the temperature fluctuates, stop adding and subtracting water to try to keep it at dead on 65 every minute of the day. Assuming temperature swings in a 48 to 72 hour period there are bound to be swings in the RH reading, but is the moisture content changing? In my opinion the chart may help you understand that although your device is changing, perhaps the water content is not.

And isn't that what we are really after in the long run, water content?

Damnit, I was really trying to stay out of this thread.

The answer here is that yes, the moisture content of the cigar is changing. To put it simply, as the temperature rises, more water is evaporating out of your cigars, so you need more water in the air to replace it. This is why keeping a constant amount of moisture in the air won't give you the results you want.

True that. That's why it's called relative humidity.

Your hygrometer will show the RH without having to resort to quantum physics to try and figure it all out.

You shouldn't. Any effort made in good faith shouldn't.

That is put much more eloquently than I could ever do - I would rather people reference your dialogue than mine. It's simply well put.

My chart is merely meant to illustrate that there is change in the RH reading as temperatures change - all the while the absolute moisture ([SIZE=3]gm/m3)[/SIZE] in the humidor remains the same. I've witnessed firsthand many people 'chasing' their RH readings trying to add or remove moisture, assuming their humidor is all over the place. In reality, even a cheap humidor or coolerdor will hold a steady moisture content. As a couple others (well regarded members) in this thread have eluded to, don't worry about the movement of the gauge it’s simply a reaction to temperature swings.

Yes, the "movement of the gauge" is in reaction to temperature swings, but that doesn't mean that it doesn't have an effect on your cigars.

Shaggy neither could you or I and I agree with Chip that each person likes their smokes the way the like it,I would have never had a 60% humi before but tried it after some long conservations with Chip and I do have one now and I have certain sticks that I keep in there and love the taste it produces

Yer kidding, right?
No one ever listens to me.....

See ya in a few days....it's such a long trip over to yer place...
