We have 6 different greenhouses 5 of which are tropical to subtropical one greenhouse is for hardy palms and gets around 30 to 40 at night karosine is the heat source. The two new greenhouses are 45 ft long and 20 ft wide they have radiant heated flooring. The cement floor has tubes with hot water pumped through it. To keep the floor at 65f. Two other greenhouses have hot water pumped through radiator like fans that throw the heat out. The radiant heated floors are the best source of heat I have seen. We use a heatmor wood burning stove to heat these 4 greenhouses. We get as low as -10f and keep the greenhouses no lower than 55f. The largest greenhouse is 80ft long 30 ft wide 22ft roof.

here is a pic of the small greenhouses getting the flooring put in.
