Greenhouse for highland Nepenthes

[nepenthes99]

Hello,
I have a 6x8 greenhouse that I am using to grow annual Drosera for the summer. It is made out of flexible, semitransparent plastic sheeting which is relatively thin. I am wondering if I could use this greenhouse for Nepenthes in winter if I have a space heater going.
Thanks,

Uninsulated plastics are unsuitable for a greenhouse in your climate, in terms of heating for the winter. It will cost a fortune to keep it above freezing come January!
