I bought this 6 months ago it took a week to properly seasons the unit. With my unit I prepped it just a little differently than most I pulled all the wood shelves out and whipped them down in with distilled water and replaced them and to get the humidity to 70% of a week and then pulled them back and brush them down in apple crown royal. Replaced them back in the unit with 72% boveda packets and the holding tank filled it with apple crown royal. The unit has a beautiful smell the cigars come out beautiful with a wonderful smoke. I replaced the hydrometer with an electronic meter for accurate readings.
