In the '80s California, I had some nudist, hippie neighbors. And of course they did hydroponics (not just for pot), but did grow some vegetables including tomatoes in both horizontal vats and vertical trellises. I really think it's a lot more efficient because it uses less far less land than current methods. (Btw: don't buy products which contain palm oil due to the prevalence of "green washed" intermediaries lying to downsteam suppliers, which in turn leads to persistent forest -clearing fires and land theft in places like Borneo and Indonesia to grow massive palm oil plantations to make cheap, Western consumer goods.)
