Missing key numbers and exaggerated claims.
Tyler, You make the statement that local residents are willing to pay a "premium for locally grown products." That statement is relatively useless without quantification - as in how much of a premium? and for quantity of product?
Food product markets are notorious for providing very small premiums for both quality and freshness at commercial scale. Over estimating the "freshness" premium and the number of buyers willing to pay a premium is one of - if not the most common fatal mistakes novice food producers make. Defining the niche economics obviously defines the potential of the venture.
And, a second mistake. This isn't by far the world's first vertical farm. Hydroponic producers have been doing stacked growing for decades, and long before them - ever hear of the Hanging Gardens of Babylon?
