Thanks again guys, appreciate all the advice.
May I be allowed a quick somewhat irrelevant question (with the subj.) in order to avoid creating a new topic? If yes,the question is what's the deal with these Bovedas?
Two calibrated hygrometers in my good air-tight tupperdor used to say RH was at 72% with the 69-Bovedas i had, so 3% more. So I switch to 65-Bovedas and now I have 69% in the tupperdor and that is 4% over.
I do not get it because a) Boveda claim that the packs are +/- 1 or 2% off the claimed value on the pack and b) they say you cannot use too many Bovedas.
Granted I am using double the recommended amount (2 60gr packs instead of 1 for a tupperdor that can accommodate 25 sticks) but I only did it to make sure everything is humidified ok and to make the packs last longer.
Am I missing something here?
