For a small green house simple heat lamps would be just fine with a small fan to circulate the air.
you really only need to keep the plants above freezing.
In this way the plants are better acclimated for the finale planting in the spring.

I turn off the heater vents in my extra bed room where I start my plants and it gets to around 40 degrees in there.
In this way they do not go through cold shock.
