Hi bugman,

You could have a N. ventrata which is a hybrid of alata and ventricosa. In any case, they all require similar care and are good plants for indoor growing. Good thinking on getting it out of the potting soil. One good thing about Nepenthes is that they are more tolerant of hard water than other carnivorous plants, so they can hold out longer.

As for soil, you will have to change out the perlite every year as that breaks down and becomes toxic to Nepenthes. What a lot of people use is a 1/3 mix each of orchid bark, coconut husk, and peat moss. That mix gives maximum drainage and supplies acidic soil at the same time. Nepenthes like their roots in moist soil, but hate standing water, so never leave a tray under the pot, just let it drain out. Water it once every 2-4 days as a house plant. It is a highland, so is less finicky than the ultr-highlands. It can adapt to a range of temperatures and humidity levels. Give it good partial sun in a morning or all day sun window. They typically live near trees, so they would get direct sun for a short time through the leaves and branches of the trees and shading part of time each day. Try to replicate those conditions or go with about 6000-12000 lumens of florescent shop lights or 100 watt compact florescent lights about 5-6 inches from the plant.

Mist it once a day to raise the ambient humidity a bit for a few hours.

After that care, just leave it alone and watch it catch all of the flies and roaches.
