greenhouse Greenhouse question for Central California

[SavinaRed]

My neighbor gave me a small metal framed 8x10 greenhouse with the clear plastic. Can I keep pepper plants alive without adding a heat source through the winter ? Thanks !

Your frost time is from early Dec to late Feb. I predict about two hard frost in that time, in which you should prolly supplement heat during the night hours of a 2-3 day frost. Other than that I think it's totally doable.

Agreed. A small space heater with a thermostat on the lowest setting should serve just fine. It should only kick on during the wee hours. I have mine on a small, footstool to keep it off the ground and it works well with outside night temps into the low 20s.
 
Something like this.
