Ahhh, Mother Nature is so surprising. I am currently growing my
N.rafflesiana, my most favorite of the Nepenthes, in a Phototron where
the humidity is about 40% (same as the house). It pitchers well and
grows like a weed. The one thing it hates is to have inconsistant
watering routines. I have to keep it consistantly wet all the time,
otherwise the traps die (quickly). It responds very well to Superthrive
and a 1/8 teaspoon of Miracid mper gallon of water fertilizing every two
months.
