Yes, Virginia greenhouses are usually warm … for three primary reasons:
First, they are all glass in order to capture the sun’s rays. And we all know that sunlight is needed to help plants perform photosynthesis.
In fact, often in the summer, greenhouse owners need to coat their glass with an opaque agent to reflect some of this warming sun.
Secondly, photosynthesis requires water … so greenhouse owners maintain a very humid atmosphere … and higher humidity makes you feel warmer.
Thirdly, greenhouse owners often goose plant growth by feeding them extra carbon dioxide … which is the other important requisite for plant photosynthesis. And how do they generate this CO2 you ask? They most often burn propane or natural gas … which, as you can imagine, also produces heat.
So, Pilgrim, when you hear of “greenhouse gases” making things warm … you are, once again, being deceived by your betters.
For their own nefarious reasons.
STAND UP FOR CO2!

The greenhouse effect describes a process of heating, where the heat from the sun is trapped by the enclosed glass and cannot escape into the atmosphere to evaporate. So the greenhouse heats up.
Gases that trap heat in the Earth's atmosphere are called greenhouse gases because they act like the glass in a greenhouse. They do not originate in greenhouses. Nor are they created by growers heating their greenhouses in cold weather.
Don't conflate things with your devious wordplay.
