Mobile beat me to it! I was just about to post this climate statistics URL:

Even in January and February, when this region is the warmest of the year, the average nighttime lows are in the mid-fifties Fahrenheit. Daytime highs, on average, do not exceed eighty Fahrenheit. Now, while many folks like elgecko do successfully grow the species in conditions that are considerably outside the plants normal temperature range, I prefer to mirror the climate conditions as found in habitat. Are my results likely to be better than someone growing theirs in a terrarium in typical household temps? Well, maybe....maybe not. What all these varied experiences suggest is that
Cephalotus, as far as temperature tolerance is concerned, is a very adaptable species as long as its core needs are met. I prefer to research a species' habitat conditions and emulate them as best I can. I believe that some knowledge of the environmental conditions of the plants you care for is an asset when trying to set up a grow space for them.
FYI: my
Cephalotus are growing in my highland
Nepenthes house, right next to the south wall where they get full sun exposure through the glass. Because the containers are exposed to direct sunlight, I have chosen pale cream-colored ceramic pots to reduce the solar gain and therefore maintain a cool soil temperature, something I believe is crucial to root health for the species. If you plant in dark colored pots, you can't site them where the pot will heat up in the sun! Ceramic pots also tend to moderate the soil temperature better than plastic pots, in my experience.
You've all probably seen this:
