Upon reflection, Allofus123 is most likely correct. While I have renewed a smoke or 2 with the Salt (which will automatically bring RH to 75% in the container), It is very subject to cracking them. Gradual is allways better, I just never figured out how to regulate RH at anything other than 65% (Climaxx Media), 70% (PPG 50/50) or 75% (Saltpaste). If you have a way to do it the way Allofus suggested, it will obviously be better.Then again, as has been said, if they are really dried out, better to just toss em and get some that have the oils still in them.
