1. What are the little specks that appear to be moving around the soil from the very beginning of the video? Some kind of mite? Nematode? 2. Is it really this easy to get a closed ecosystem going? I suppose the rubber seal is still somewhat permeable, but I assumed the oxygen in the jar would be depleted quickly, and all that would be left would be anaerobic bacteria. In this jar he seemed to have fungus and plants growing, and the little specks (if alive) kept going the whole time.
