Here is one link that talks a little about a 'hot box' - http://www.penturners.org/forum/f43/casting-colder-weather-advice-needed-90821/.
Essentially, it's using a cardboard box and a 60 watt light bulb to create a low-powered oven. If you're using PVC pipe, be careful that you don't get too much heat in there! I tried pointing 2 60 watt bulbs at my PVC molds, and they slightly warped while drying. That makes it MUCH harder to remove the blanks once they dry!
Edit: found another good link!

I just use a $20 toaster oven from Walmart. Color, catalyze, mix in the mold, put in the oven for two rounds of 30 minutes at 150 degrees F.

Try light box, and use of a cooler and light bulb have been mentioned.
