How to convert the following recipe
How do I convert the following recipe I got from a german baking forum. As quite usual in Germany they use SD and commercial yeast. Since it is too difficult without a proof box to hold the temperature @ 80 degree for 16 hours I like to bake this bread using only yeast. I am sure I can do it with a preferment but I'd like to have some input from this knowledgeable forum.
Haferflocken Brot (Oat bread)
mix and let ferment for 16 hours@80 F
300gr. oats roasted
600gr hot water

120gr Rye flour
200 gr. Water

I have done this bread according to the recipe. ( I posted a pic, I think "German Oat meal bread)I like it very much. It is very moist und the oat flavour is wonderful. Thanks for your input.
