Here's a potentially much better idea. Build server farms near greenhouses and pipe the heat over to them. Heating is the single largest expense for greenhouses, more even than labor.
If the servers were in modular units such as semi trailers you could place however many you needed for the size of greenhouse range. Since greenhouses tend to be grouped in regions such as Cleveland, OH and Kalamazoo, MI you'd have your servers in a small enough area for a single person to be able to service them.
