Good to know. I pitched US-05 last night at 68F as I couldn't chill it down to fermentation temp (around 64F) with my tap water. So, I had to let it fall down to pitching temp, which I wasn't a fan of doing. Hoping it's okay, guess it's gonna be a learning experience. But this morning this was still no activity. Did notice the temperature change was sucking some of the sanitizer solution from the airlock into the fermenter though. Argh.
Are you saying you pitched at 68F and then let it fall to 64F? If that's the case, you're fine as long as you can keep the temp from ramping back up (which active fermentation will cause to happen).
And on the airlock thing, that's exactly the reason you put sanitizer in the airlock. No harm done.
I figured as much. Thanks for your input. I'm not used to NOT being able to chill the wort down to fermentation temps or lower. So this is kind of a first. My fermentation chamber is ranging from 58F or so to about 64F. So I don't think it'll be too much of an issue.
For those of you with Johnson controllers, what are your settings? Mine are:
SP = 64F
diF = 2
aSD = 10
The others are zero, I think. I seem to have about a 7 or 8 degree temp swing.
EDIT: I guess I should mention that this is my first beer with a the chest freezer and Johnson Controller. The temperature probe is dangling in the air.
