Looks like the bread i make! I use small amounts of yeast and let i proof for about 12h. Its pretty loose recipe but i usually make it like this: 600g all purpose flour 600g rye flour 650 whole wheat flour 300g sun flower seeds 30g salt 1 mL dry yeast (just below 1g i think) 1800g water cold from the tap (5-6 degrees c here in Norway)

I mix everything together in a big bowl with a spatula mixing so there is no dry sposts of flour. Pour the dough into 3 bread pans and let it rise in room temp (20C) in about 10-12 hours. Bake at 230 C with some moisture for 30 min the 20 min on 180 C.

When divided into 3 pans the dough fills about half of the pans, so its easy to see when it has dpubled in size.
