WHEN is ferment supposed to start foaming

[Cornbread]

It seems like one of the most asked questions is about "My wash is not foaming or bubbling" Help Me! I wish you real experienced folks would tell us if it is suppose to start when we pitch yeast, 10 minutes later, next day or what? Also maybe tell us what yeast to use (like Brewers or Bakers). (does brewer's yeast also add nutrients?) Maybe even "reinterate" the temperature to pitch it. ( I see 6 different answers on here for that.) Do we stir it immediately after pitching? Do we put air lock on immediately & leave it alone ..or do we stir it daily for the first few days. I have seen all of these answers. I thought maybe one of you wonderful master distillers could try to make it more simple for us numbnuts. Read? Yes, I read. I read things like "don't use nutrients for grain washes". I read "Use nutrients for all washes" . I hardly ever read how much nutrients. We (me anyway) are dumber than you think. We love you guys so much........
