Hi I like your use of found and used items. I have moved to a place with a broken concrete yard. So I'm looking for inspiration for different things to grow in. I have the black pots too, and several council bins! I haven't tried growing in them yet. I'm wondering about different composting ideas over concrete and also perhaps composting in place in the big green bins. I started with growing leaves and berries over the last couple of years in my previous place. I like your ideas. I think these kinds of ideas will be the future for many urban people as we try and adapt our lives to climate change, and use what is available, including learning to seed save.
