Moved across the country recently, the new oven is tiny and ancient, but on the second try, I had a good outcome!
These loaves had no recipe, flying completely by the seat of my pants, with very young, arguably not ready starter.
850g bread flour
70g whole wheat
80g wheat germ
400g young, questionable starter
700g water
Small pinch active dry yeast to supplement the poor starter
Mixed all, 20min autolyse
Mixed 21g salt in 50g water then added to the dough.
Three folds over the first couple hours. Total bulk ferment was maybe.....four hours? At which point I preheated the oven for one loaf and put the other on the fridge until around noon the next day, so around 18 hours in the fridge.
First loaf, no fridge time

Second loaf

wow that is some bread to be proud of
