This seems like a bad idea. As was already pointed out, any combustion follows this formula.

Fuel + Oxygen -------> CO2 + h2O + gas (somtimes)

( -----> means reacts to produce, basically equals )

The c02 and h20 will be fine for your plant, but, the other products of the reaction may not be.
If you burn a candle, you will have unexpected gas products (... what makes the candle smell nice? chemicals - which will combust too, the same goes with the candle's wax, colour ect...)

The combustion forumla shown above is called COMPLETE combustion. Complete combustion is rare.

In most cases, you will have INCOMPLETE combustion - wich is a lack of the oxygen particles in the reaction. In incomplete combustion, undetermined products at unbalanced amounts will be produced - these may/probably will will hurt your plants.

Therefore, I would stay away from the candle. Only large growers/grows should need additional CO2 anyways. If you feel the need for CO2, you can buy CO2 in tanks, and regulate the flow to the plants.

Hope that helps -
