It will vary, Davita. You're looking for the starter to be bubbly and slightly domed. In our kitchens it took about 15 hours. The temperature in your home is perfectly fine, things just may take a little longer. You can help speed things along with your dough by using water that's around 100°F. Happy baking! Annabelle@KAF
