so ive had my first brew fermetining for 6 days and the airlock has stopped bubbling. im gonna leave it for at least another week in primary.its about a 6% abv partial extract ipa.i plan on dry hopping in secondary also.my stick on primary has been about 67 and gradually dropping as fermentation slows down.right now its 63,same as ambiant temp. im just confused if i should be keeping it warmer or not.im not exactly sure when to cold crash. i know the yeast needs more time to cleanup.my temps might have been a little high but i was having a hard time regulating temps with a blanket.im probably just worrying becase it is my first one.any advice you can give me about temperature and length of time i would appreciate it.thanks
