The main thing you want to try and find is a “frost free” refrigerator. Those have a dehumidifier that helps maintain the humidity level. At least that’s the information I’ve found. I just bought this from Walmart and will be doing my first attempt using this fridge:https://www.walmart.com/ip/Frigidaire-10-Cu-Ft-Frost-Free-Top-Mount-Refrigerator-Black-EFR1033/17433763370?classType=VARIANT&athbdg=L1103&from=/search I looked at used options first, but didn’t want to deal with cleaning and sanitizing something so then I tried to find the cheapest new fridge that was frost free. I only have a 2x4 tent so I’m only harvesting 2 plants. This should be more room than I need, but if your harvest is large, you’ll need a full sized fridge. This is a medium/small one. I couldn’t find a frost free fridge that was smaller than 7 cu ft. This one is 10 cu ft.
