Fast fermentation

[deafcone]

Just made a brown ale from a kit. The OG was 1.050. I used safale-04 yeast. Just poured it right into Carboy on top of wort.
It's been a little over 24 hours and the fermentation was quick but now the airlock shows no bubbles at all.
When I put the yeast in the temp read 72 on the thermometer tape on the Carboy. Next morning no activity,so I shook itbpunand checked the temp. It was 54. Added warm water to water bath Carboy was in. Started fermenting within 30 minutes as temp rose to 68.
Now still at 68 and no air bubbles in air lock.
Is a 24 hour fermentation ok? There's a huge Krausen like always. Will leave in primary rest of week then transfer and possibly bottle depending on gravity reading. Just surprised by the quick fermentation. Only thing different I. This brew was a full pound of candi sugar in kit.

Try to stabilize the temperature the best you can. I doubt fermentation is done after 24 hours, so I'd give it the full week in the primary and then start taking hydrometer readings. Once you have 3 readings 3 days in a row that are the same, fermentation should be done. The Kräusen should fall back to the bottom of the fermenter, too.

tgolanos,

if the temperature drops too much, the fermentation may stop without being done, right?

I have a beer fermentation that started at 74 F and now it is 68 F. The fermentation seems to be stuck at 1.020... I am not sure if the fermentation is done because the FG is still high...

temp is now 72, Krausen is starting to fall. At close look there is movement like it does when fermenting. So all seems good. Just never had that quick of a ferment before. Leaving alone for a week.
