There is an economic analysis of smaller scale greenhouse and vertical farming. The all-in delivered cost of a pound of greens grown in a commercial greenhouse is estimated to be $2.33 per pound. It cost $18.3 million to build 280,000 square feet (2.6 hectares) of commercial greenhouse in the USA. The total cost to grow would be just over $3.0 million per year for 2 million pounds of greens or $1.52 per pound. BrightFarms employs 165 people for the three greenhouses. $1.10 per pound consists of employee costs.
