I'd like to build a little cold room. Be able to Keep humidity down while aging it.
Good luck!
Look into a device called a Cold Bot. That an a $300 room air conditioned will turn a small insulated room into great walk in cooler
the Cool Bot will cost a bit over $300 plus the a/c unit. They say that the Cool Bot can't use the rated BTU's of the a/c so you need a larger one than what you might figure.
Plus, you need a very well insulated room, including the floor.
An a/c will shut off at about 60F. The Cool Bot will keep it running to a much lower temp.
COOL BOT We've been thinking about building a cooler with one of these to store garden stuff plus meat.
