Gap in Cedar between humdior wall and floor...Bad Seal? (With Pics)

You didn't say in your original post how long you've been seasoning your humidor. Sometimes it can take 6-8 weeks for humidity to stabilize in a humi. It's not uncommon for a new humidor to be a little "thirsty". The gap in the cedar wouldn't seem to be much of an issue other than cosmetic, to me.
