Yep....keeping it too warm will result in a faster ferment and more smell. A nice, cool and dark space serves it well when you want a more slower paced ferment and less odor. I keep a lid on mine that's just barely cracked on one side and I don't get a whiff of it until I actually open it fully and stir it up.
Ok, the basement is 60ish degrees. Should I move it out? Outside goes down to 20 degrees, though.
