I'm using this for the first time too. Temp kept dropping in my ac'd house. I live in Florida and it's July, so I put it in an igloo ice cube and put it in a somewhat insulated shed which kept it around 85-90 degrees. Then it started raining so I brought it in and put a heat pad in the cooler to keep the temp the same. I'm thinking about calling it "The Prodigal Son Saison" since I kicked it's somewhat unruly a$$ out and it's been good since it returned indoors.
I had airlock activity starting at about 11 hours and stopped at about 24 hours. It's been a week now and I have a good layer of bubbles, and I'm at 1.034, so I know it is going well from everything else I have read about this yeast. It has a nice banana bread smell to it. I'll secondary mine, but not for at least 4 weeks or longer depending on when it gets to single digits.
Good luck.
