I only have room for one bucket in my ferm chamber and want to brew again, my oatmeal stout with S04 has hit FG so I assume its ok to take it out and let it chill in my closet. Temps range from 55-65 in there these days.
Thats fine. Once the primary fermentation is done (i.e. bubbling stops, krausen drops, etc) you're good to move it to a spot that may be a little warmer. This is actually encouraged so the yeast can go and clean up the diacetyl. With wlp001 I usually ferment around 65 until fermentation subsides and let it warm up to ~70-72
