Growing wheat and grinding it out into flour isn’t something I’ve ever heard anyone take on as a hobby before. Having all that actually cost less (including time) than buying bread would be a huge achievement!
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.
