I am seeing a growing trend towards this type of innovative growing for large cities with little or no land but a want for fresh and safe food. And while I absolutely admire this type of out of the box thinking and creativity, I am always left wondering how sustainable is something like this and is the final product as nutritious and healthy as regular soil growing methods? I realize right now it might not even matter to the people doing it as the creative, fun and growing something yourself aspect is appealing all by itself. But is it a potential long term answer or more of a hobby?
It appears to be an input intensive method nutrient wise, but having really no knowledge of the nutrient side of things for these hydroponic systems I guess I don't really know. Where do the nutrients for these systems come from?
