Making a bread starter from scratch / No mid-dumping

there are many people who like sourdough bread, right?
You can easily make Levain.
There is no process of discarding mixture in the middle.
It's winter where I live, so I put it in the corner of a warm sunroom.. When you make it in the summer, it seems to ferment well anywhere.
Just be careful, don't forget to feed each day
**It is normal for the starter to smell sour.
So the name is Sourdough.
**Please add a little bit of flour (see the video )
As you can see in the video, I think the fourth day was a turning point for me. Even if bubbles do not occur well in the middle of growing fermented species, do not give up and continue to feed
you will surely succeed
