I was checking out the humi and pulled a H Upman 1844 natural tubo to burn. I popped the tube open and out came a nice little stick with the beginnings of mold? I thought WTH? I thought these babys were hermeticially sealed like Twinkies(c) or something. So I think back a few weeks when my cooler humidity went way up and guess this was the cause. So my question is, how can tubos be sealed and strill suffer from excessive humidity? The remaining 8 from this batch are now naked in my regular humi.....Should I open ALL the tubos or put the rest in for "adjustment" ?
