Growing a few acres of something seems like a very cool project. Did you / your dad already have the land before you decided to try it out? Do you think you would have done it again if you had made money? Would you recommend it as a project to someone else?
We moved to this sort of village where our house had a few fields, and I think my dad entertained the idea of trying to do it seriously (he did have past experience but was working in a different field and had an unrelated university degree). In the end it was just a lot of hard work, some of it fun (I got to drive a tractor at 14!), but most of it was tedious and not very rewarding. I guess had we turned a little profit this would make us more incentivised, but also about a year later we moved away to a city so it wasn't practical anymore.
I'd recommend starting with a pretty small field and not going commercial on the first try.
