Adjust dough fermentation time for a different ambient temperature.
Microbial activity roughly doubles for about every ten degree rise, so cooler rooms stretch ferment time and warmer ones shrink it. Ambient temperature swings of even a few degrees shift ferment timing noticeably, which is why bakers track it.
Fermentation Time
Adjusted = base time x 2^((base temp - actual temp) / 10)
