Won't to heat my greenhouse which will be cheaper gas or electric ?

I have got an oil filled electric radiator in mine and it seems to be easy to regulate the temperature looking at the thermometer and turning the stat on the rad to temp i prefer.

dont really know but i think its better than gas cos i can control the rad with the stat.

not sure about the cost but I would say electric is more reliable ! And it doesn't give of moisture which you don't need at this time of year . But that's just my op.
