Cedar trays are out there, that's what I'd do.
Check with Kayla the woman
@cheaphumidors
and she'll hook you up and we have a Cigar Bum discount code with them.
I agree with this wholeheartedly, and have purchased my trays from Kayla. I also have boxes in my coolidor and haven't had a problem with humidity at all. Sean's idea of breaking up boxes is certainly viable as well. Use whatever method allows you to fill'er up!
