Why do plants grown in greenhouses in winter rarely grow as fast as the same type of plant grown outside in the summer even if the temperatures are the same?

A greenhouse, using the greenhouse affect, does help the plants grow faster.
Let me try and put this is simplest terms.
Heat, is a measurment of energy. And plants need energy to grow, which is why they need heat to grow.
The sun emits radiant energy. Radiant energy is pretty much heat that is transferred through an empty gap, like space. ( this does not inclue air ).
Radiant energy can transfer through the glass/plastic of the greenhouse and gets obsorbed by the plants. Then the plants emit their own radiant energy, except it is not the same as the energy it took in. The radiant energy the plants inside the greenhouse emit can not penatrate through the glass/plastic of the greenhouse, trapping all heat inside.
