Chris, I understand what you're saying as well, but you're making the assumption that this person is done with his renovation. Maybe he's brand new to
gardening in general and is excited but doesn't really know where or how to start - his first thought is, "I need a blank slate!" Maybe the landlord is letting him use the space on the condition that he clean it up. Maybe he saved all that biomass out of frame and is struggling to figure out what to do with it. Who knows? I'm not trying to be argumentative, but I just think that coming down on someone for trying to make their space better (to them), especially when it comes to growing food, is counter-productive to relaying the message of
permaculture in general. Everything is an experiment because everyone is dealing with different growing conditions - it is an ongoing learning process to figure out what works best in one's given situation. This young man will likely discover the heat issues you mentioned, and as a result, strive to learn more about gardening and maybe even
permaculture approaches. Anyone that is actively trying to know their food more intimately, via
permaculture or not, is doing something good in my book.
