Hi Amber,
You may consider building a bubble wrap dome inside the greenhouse.
I used
this to good effect last winter in a large DIY propagator with
heating
cables controlled by a lighting dimmer switch.
Unless I misunderstand you, you have a deadly system in mind, unless
you are using a transformer and low voltage cables.
