excess moisture in baccy jars

[NeverBend]

Just took a couple minutes to check on my stocks, rearrange some jars etc and I noticed a couple seem to have excessive moisture in them, as in the glass is steaming up. Just wondering if I should open them up for a while to bring the moisture down? I'm just worried about mold so looking for some input. I have about 8 jars total and there's only 3 I can tell that have this issue going on.
Picture isn't very clear but you can see the glass is slightly fogged up.

Hi Blake,

What mixture is in the jars and how moist was it going in? Air in jars will take moisture out of the tobacco until it reaches rH stasis and if the tobacco was wet you I expect that it can cause condensation.

Following Brandon and Mark's comments; Is it near a heat source? Oil burner or washer/dryer? Was there other tobacco in the jars previously without cleaning (I've done this)?

If it was wet going in, dry all of it some, clean and dry the jar and put it back and see how it does. Of course you could just smoke it all real quick.

They're Carter Hall, Captain Black White and the "best of the rest" mix I got from Tobias. The captain black was a little moist when I put it in but no worse than any of my other tobaccos, the other 2 weren't very moist at all. They were all new jars, never used for anything before. Washed out and left to sit (open) for about a week before filling. My office in the basement is in a corner with no window, no heat source, just an unused room I store my hobby junk in (guitars, golf clubs etc...) no heat sources at all.

I've had them open now since about 10 pm last night and the "fog" hasn't dissipated at all. I wiped some with my finger and it almost does feel a bit oily, so maybe empty them out and give them a cleaning?

How's the ambient rH (relative humidity) where you live? They're closed jars but basements can be moist and if you closed them there then the air inside the jars might have been moist.

On the surface it does sounds like heat, perhaps sunlight. Doesn't take much sunlight to cause some mist and there'll be more if the tobacco is moist and less ability to reabsorb it. I'll ruminate and see if I can think of anything else.

This would leave me to believe that it's not just water condensation. Possibly PG?
