I have a small N. bicalcarata X khasiana seedling (currently has pitchers
about 2 in (2.5 cm) in height) that I purchased from California Carnivores
this past July. It resides in a terrarium under fluorescent lights with
daytime temps typically ranging from 79-86F (26-30C) and night temps 69-74F
(20-23C). However during Sept. the day temps ranged from 90-95F (32-35)
for about a 5 day period. I noted no harm to the plant nor any significant
change in growth rate as a result of the hot spell. It would appear in
this hybrid that its lowland parent has given it a tolerance for warmer
temps, although I don't yet know how well it tolerates cooler temps.
