Adam Ragusea actually just did a 2 part video on growing his own bread from scratch in his backyard. Part 2 just came out a few hours ago.

Spoiler :P it definitely took way more time an effort than buying flour from the store and making bread. And the final product was a pretty poor loaf of bread because he couldn't find a way to buy the same type of wheat most farms use and had to settle for "animal feed" quality seeds.
