It will help.
We bought a refillable lamp oil insert for ours to achieve cleaner and longer burns. It work great.
Without the candle you could hang a fine cotton sheet up near the interior apex. This cloth will collect the moisture and frost up throughout the night.
Come morning, you carefully pull the cloth down and shake it off outside.
The best thing to do is have a wide open low and high vent. Lots of flow keep the moisture from settling on the tent walls.
Though we don't use any of these tricks anymore as we're in a hot tipi now.
