We had two horticulture classes in my high school - one was a very well-funded class ran by a professional (in part because the greenhouse they used was actually part of his business), the other had no funding whatsoever. I was in the latter. We barely grew anything ourselves, most of our year was spent setting things up for future us, like building the irrigation system for our own cheap greenhouse and tearing out stumps and bushes where we were gonna build planters. And it was all done without having somebody hovering over our shoulders.

It was the only time in my school life I remember not feeling like my soul was leaving my body. It even got me into reasonably good shape, when previously I was scrawny as fuck and couldn't be assed to work out for its own sake. Every school should have something like that. It's no wonder so many people are neurotic when they spent most of their formative years sitting on their ass doing busywork with no tangible reward.
