I am in AZ and the whole humidification thing is a PIA. I had a pound or so of the Indonesian Tambolaka get all moldy on me and I cant remember if I had a humi pack in the large cigar jar. The rest of my opened tins and bags are in a large cooler with a humi jar in it. So far I have not had anything else get moldy in 3 yrs. If I was not in the SW I probably would not worry about keeping the humidity up. But AZ can dry stuff out fast.......thoughts??
