Ok, my first batch has been fermenting steadily since Dec 13. The fermenter is in a shower/tub in a small unused bathroom with a ceiling vent that has a thermostat controlled heater fan in it. I have had the heater set at around 70 degrees. I have a concern. The temperature on the LCD thermometer on the vessel has now dropped down below 60, yet it is still fermenting...(ive read that yeast goes dormant below 60). The yeast is us safale 05. I turned the heater up above 70, but vessel temp has not changed. I just now have wrapped the fermenter in a fleece blanket and stuck a new adhesive thermometer on it in case the first one was faulty(but the new one just dropped down to 58 as well). I feel as if since its still actively fermenting i shouldn't really worry, but still would like some friendly advice and/or reassurance that everything is going to be ok. Thanks!
