After these folds (2 hours and 15 minutes have gone by), let the dough rest for the remainder of bulk fermentation.
At 78°F (25°C) ambient temperature, bulk fermentation should go for about 4 hours. Perform six sets of stretch and folds during the bulk. The first three are at 15-minute intervals, and the last three are at 30-minute intervals. After these folds (2 hours and 15 minutes have gone by), let the dough rest for the remainder of bulk fermentation.
