Nepenthes highland are pitcher trap carnivorous plants that live in tropical mountains characterized by warm days but a sharp drop in temperature at night. The ideal temperatures are between 24-26 degrees during the day and 12-14 degrees at night. They love the evening humidity which brings relief from the strong daytime sun. Some species are more tolerant of summer temperatures but extremely hot days above 28 degrees or very cold nights below 8 degrees should be avoided. Nepenthes intermediate, on the other hand, are more tolerant of daytime heat but cannot tolerate frost or excessively cold evening temperatures. The ideal temperature for intermediate crops is between 28-30 degrees during the day and 14-16 degrees at night.
