Vertical farming is catching the attention from people but we all know that urban land is far more expensive that farm land, and the cost of creating such a concept and powering up a farmscraper for lights, controlling ambient temperatures and the like, will not be a cheap exercise. So just how much will this produce cost the consumer? It sounds as if it would cost them far more than what they could expect to pay for conventionally grown food. I even think that the green house effect will be another criteria, the amount of pollution created will be much higher than that from field produce.
