Read the article of so called” Skyscrper Farm” which is definitely doable. However, we have to consider “is it practical?

Yes it could be calculated for a huge productivity and so many advantages e.g. health food, city clearer, save more transportation costs,———

It has to be reevaluated for the costs such as
building cost?
Sunlight enough?
Water and control System cost?
Operation Costs?
Maintanance cost?
seeds nursey? Plown costs?
Liquid fertilizer? and others……….
how much each Kg corn to be under this condition vs regular
corn
Believe, it would be promising if the prices not too much
difference even double, would be encouraged.

Would most interested in the model comparison if some one
could provide. Very Appreciate.
