It depends.....!
If you want to go all technical you can get a temperature probe, humidifer, humidity meter, fan to create a modicom of control over the conditions inside the fridge. If you just turned it on, lowest (ie warmest) setting then it will still be a bit chilly for ideal curing conditions. However you can mess around with switches and readings so that the fridge turns on, then gets switched off when too cold, allowed to warm up a tad, also the fan and humidifier can switch on and off etc etc.
Alternatively you can just leave it off and just take advantage of the more controlled box.
So, your call really
