Growing autos in a greenhouse in winter

Is this possible and will the yield be the same? Where I live, the lowest temperature will be low 20s outside the greenhouse. The inside of my greenhouse will never freeze and go below 32f.

Any tips , tricks or which strains to choose?

Issue is day length, many autos do poorly without at least 14 hours light.

Spring to fall equinox fine.

If I were to grow autos in the winter greenhouse I would build a tent and add heat light and ventilation. Inside the greenhouse. Make it a black out tent if you do not want to light up the whole world in the process.

I will likely grow this way, as I have a breeding project that will take 3 generations to get what I want.

Mephisto does well for me in the greenhouse with less than optimal conditions
