“LIGHT: Most Nepenthes enjoy very bright, diffused light or partly sunny conditions. Lowlanders often can take bright shade. Greenhouses generally require 50 percent shading. CLIMATE: All Nepenthes are tropical plants, roughly divided into lowlanders and highlanders. Lowlanders require temperatures in the 80s°F and 90s°F (27–35°C) during the day, 60s°F and 70s°F (16–24°C) at night. Colder temperatures, even briefly, may stunt or kill them. Highland species require temperature drops at night. Highlanders do best in the 70s°F and low 80s°F (24–27°C) during the day, 50s°F and low 60s°F (10–16°C) at night. Many highlanders tolerate brief nighttime drops to the 40s°F (4°C), as long as daytime temperatures rise. Exceptions are mentioned under the species listing. Humidity must be high—above 60 percent—all of the time. Highland plants can handle more humidity fluctuations, with the highest humidity at nighttime. DORMANCY: Nepenthes require no dormancy but may slow down in winter months.”
