i live down the shore and i keep my humidor in the den. i don't use a/c. i just leave the windows open. my humidor is never in direct sunlight. right now the temp in there is 78 degrees and the humidity is 75%. i haven't needed to add any solution since may/june when the ambient humidity started to go up. and no, beetles are not an issue.

so, is there any point in the solution or just wait till cold air comes back and dries everything up again?
