I didnt want to thread jack eventhough there is several posts a day regarding ferment temps. I guess I was being overly cautious. I brewed a gallon batch of EdWorts Haus Pale Ale yesterday, pitched at 70 with SAF-04 yeast. Put in my tub with some water (coming up 1/4 of the bottle) and wrapped in wet towels and had 2 Iced bottles in the tub. My ambient temps were 68. Today in the mail I received the sticky thermos to put on my carboy. Low and behold the temp was 54!! The turqoise color, middle display temp reading. But I have very active ferementation. I have now removed the wet towels and all water to help bump the temps up. So am I screwed? Been doing this for my last 4 batches and I have had very active fermentation. Thanks.
