After watching and discussing what earth day is/means, we had a hangout session with JT Bear. JT Bear is a gentle man from the west cost of Canada, who has youtube channel where he talks about his aquaponic set-up without hiding the problems he runs into.
We had a great time ! the students where a bit shy at the beginning, but they started to show what they had built, from top to bottom, explaining how the water flows from the bucket to the towers, as well as the difference between how on system is fed using store bought fertilizer and the other using compost tea. They showed in detail the different plants growing in the system : lettuce, spinach,"cabage" (actually Swiss chard), basil, cilantro, parsley, basil, and strawberries.
