Many years ago, I took a trip to Biosphere 2, out near Tucson. They had a small aquaponics system set up. It’s super neat because fish and small animals directly impact the health of the plants they’re helping grow.
Well, years after that, we worked on building an aquaponics system in our client’s backyard. It was a lot of work, and we didn’t see the results for a long while. I will say it was one of the coolest projects I have ever worked on.
