In a large mixing bowl, combine the warm water and honey. Sprinkle the active dry yeast over the water and let it sit for about 5-10 minutes until it becomes frothy.
While the yeast is activating, in a separate bowl, whisk together the bread flour and salt.
Once the yeast mixture is frothy, gradually add the flour mixture to the bowl, stirring with a wooden spoon until a shaggy dough forms.
Fold in the toasted sunflower seeds, pumpkin seeds, sesame seeds, flax seeds, and poppy seeds to the dough.
Lightly flour a clean surface and transfer the dough onto it. Knead for about 5-7 minutes until smooth and elastic.
Place the kneaded dough into a lightly greased bowl, cover it with a kitchen towel, and let it rise in a warm place for 1-2 hours or until doubled in size.
Punch down the dough gently to release air. Turn onto a floured surface and shape into a round loaf.
Place the shaped dough on parchment paper. Cover and let rise for another 30-45 minutes.
About 30 minutes before baking, preheat oven to 450°F (232°C) with the Dutch oven inside.
Carefully remove the hot Dutch oven. Use parchment paper to lift dough into pot. Sprinkle additional seeds if desired. Cover with lid and bake for 30 minutes.
Remove lid and bake an additional 15-20 minutes until golden brown and hollow sounding when tapped.
Remove bread from Dutch oven and cool on a wire rack for at least 30 minutes before slicing.
