I just now perfected my setup for now till me and my wife move into our own house in the near future. It's a very nice vintage Marvel beverage fridge that I converted to a dry aging station. . It's a 6.77 pounder prime rib sitting on a 2lb layer of Himalayan sea salt, and i used a computer fan to circulate the air.
And of course the Ranco ETC temperature controller at a constant 34-35 degrees :)
4 day old prime rib
Prime rib after a week. Starting to dry out very nicely.
If anyone wants directions on how to do this feel free to ask :)
