Have a look at this link:
Fuel Prices
Electricity has an average price of 12.6p per kWh (assuming you're not on economy 7)
Propane starts at 9.2p, but that's for a cylinder over a metre high, which you're unlikely to be using on a greenhouse heater; smaller sizes of cylinder are between 13.3p and 26p per kWh
So your best bet is to improve insulation and use your heater as efficiently as possible - keep the plants in one partitioned-off area and heat that, get an accurate thermostat.
