Glad to help out.Good thinking Ben, thanks. I usually wrap up brewing around noon. I'll leave it out until it's under 80F
As you know I've been leaving my wort in the kettle to chill overnight sometimes I don't get back to it until the next arvo and I can honestly say I've experienced no infections doing it this way.
As long as you've got a good seal and do all this at boiling or around that time in theory you should be good.
Just remember to add some chill down time in the "more" section of the brew calc to account for extra hop issomerization.
