For aging and overflow storage of cigars a coolerador is a great asset for the cigar guys. I have found the following to be the easiest course of action:
1) Obtain a new cooler, any cooler with a hinged lid. No need for a Yeti for this, any hinged Igloo or Coleman will do. Size is up to your obsession and ability to control yourself shopping. Start here http://www.cigarbid.com/?
2) Wash inside of new cooler with scent free detergent, then baking soda.
3) Place washed and dried cooler outside in the sun for at least 1 day. Then bring it inside.
4) Get online at http://www.heartfeltindustries.com/proddetail.asp?prod=HB_1_65 and see their chart to calculate how many pounds are enough. More is better than less in this case, recovery from opening the cooler occurs faster with more. This will not over humidify. Follow bead instructions for propper amount of distilled water to add.
5) Round up spanish cedar cigar boxes or lumber and wipe down with distilled water. Place empty boxes in the cooler along with correct quantity of beads. I like boxes for loose sticks. Trays are available if you prefer. Do not put cigars in at this time. You need a digital hygrometer at this time as well, put it in the cooler. With the boxes, beads and hygrometer in the cooler, no cigars, close the lid and leave it for 3 or so days then check humidity. Should read a solid 65%. Check bead coloration according to Heartfelt reccomendations, add distilled water if required.
6) If your coolerador is reading 65% after a week of checking it, load up your smokes and forget about them for a while. Check the Hygrometer on occasion and make sure your beads are holding 65%.
Thats it. Simple.
