I have an old stand up freezer that we are no longer using. I would say it is about 25 years old. I unplugged it and cleaned it up. The seal on the door is in great shape and stays tightly shut. I am thinking of turning it into a humidor, although it is probably too big. It is about 5.5 feet high, four feet wide and four feet deep. I really didn't want to spend the cash on spanish cedar for shelves so I was thinking of just using a bunch of empty boxes and beads, along with my full boxes of course! This is down the cellar which stays cool during the summer and room temperature during the winter. Should I be concerned about not using a humidifier? Will using the empty boxes and beads be sufficient? I appreciate any suggestions.
