So I have three bathrooms in the house and my son moved out a couple of years ago. Things to do with that extra bathroom. !!! The shower makes a perfect fermentation chamber since we do not have basements or cellers in SOCal. To hold temp and humidity I used a desk fan blowing across a brick of ice. The temps held between 70F to 73F and humidity held between 70 to 75 RH. Now all I have to do is wait for another 80 days while the salami hangs out in the drying frig.
