First let me start off by saying womas are one of the easiest pythons to keep and breed. I don't pay to much attention to cooling them. The natural temp drop that occurs during winter is enough. My snake room gets down to about 75* at night during Nov., Dec., Jan., and Feb. During these months the light cycle I use is 12 on and 12 off. I start pairing them up in Dec. and continue breeding through Feb. or until a female ovulates. That's it no special tricks needed, just a slight drop in temps and a change in the light cycle. Here is a pic taken yesterday May 4th. This is my second clutch this season with one more on the way.
