Made some good progress today.
After 24 hours in the salt chamber the hygro is sitting at a solid 75% RH.
Cleaned out the cooler with dish soap and baking soda. After drying there was ZERO plastic smell, still gonna leave some newspaper in it overnight though. Went to the local after that and picked up some empty boxes.
Took a Punch box and deconstructed it since there were some really nice SC pieces in it. Put the rest of the boxes into the cooler to see how much room I'll have. I should be good for a little bit still.
I'm seasoning the loose pieces of SC now and will probably be attaching them to the sides and bottom of the cooler to help balance the humidity and give it some good aromas. Hopefully I'll get the beads here in the next couple of days and then I should be good to go for cigar storage.
