I actually asked X-Crispi this question.....he said a smaller watt bulb "MIGHT" get away with it....which means don't do this. Larger watt.....well lets just say I'm glad to see you posting.
Can you put some wet towels on the floor (don't know what kind of floor you have) and see if you can let some of the water evaporate. How long before that humidifier arrives???
