I am trying to make a wholewheat starter. For the past 6 days I have added 30 grams of wholemwheat brown flower plus 30 grams of water @ 20c. I am keeping it in an old ice cream box which is sitting outdoors where the temp is 3c at the moment.

It has started to bubble up and develope little holes in the surface. Its depth is about one and a quarter inches.

I have never tried this before so haven't a clue what I am doing! If the starter is successful, how much of it would I use to make a medium sized loaf and should the quantity of starter I have thus far (if it works!!!) big enough, or should it be considerable bigger please?

Best wishes,
