I am somewhat unclear as to how the completely recycled water is able to supply essential nutrients to the plants. I would have thought that after the third or fourth cycle, the needed minerals, micronutrients and macronutrients would have been absorbed by the plants, resulting in nutrient deficiency or toxicity. Are fertilizers added to the water on a regular basis? And if so, since the children are growing vegetables in the vertical gardens, does fertilization affect the organic designation of the products? Also, what type of soil composition is being employed? What level of sterility is being used in the soil to prevent weeds and harmful plant fungi without destroying the symbiotic relationship between beneficial bacteria that creates usable nitrogen in the soil?
