I know of two fully heated tunnels near me that seem to make a living. One starts in January, growing flowers from plugs, for eventual delivery to florists. That guy buys natural gas by the semi-truck load.

The other one does grow tomatoes, in hydro. He uses wood heat and has a crew of migrant laborers who tend the fire for him, and a pile of firewood as big as the greenhouse. He has ripe tomatoes by late April, by picking them green and gassing them. They are the worst-tasting tomatoes I have ever had, much worse than the grocery store, but he sells every one he brings. So the guy with the lowest quality is the one making the most money, because he has tomatoes before everyone else.
