It's a blessing to live in coastal Northern California. It makes growing nepenthes that much easier.
I also had success in Vermont, window sill growing ventricosa, sanguinea, and ventrata. I didn't stay long enough, after picking up the hobby, to get more plants there, but it is work-able. The snow helps to reflect the sunshine in the winter. I also had some Theobroma Cacao (chocolate), and Lemon trees growing. Then just the regular old houseplants too.
I think with neps based on my observations for the past 6 years, they need a certain amount of sunlight hours in order for pitcher production to occur, they need humidity in order to grow quickly and make bigger pitchers, and all of them other than UHLs don't like dips below 60 at night otherwise they stall until it warms up. And then the temp drop of course. I started with the plants suggested in Nepenthes Around the House as outdoor plants, intermediate and above, and experimented from there. I determined even some of the intermediates don't want to grow outside for the occasional chill even in San Diego (e.g. N.platychila I think would like indoors better over the 'Winter' months). Most of Neps can stand the low and swinging humidity, but there are a couple I've encountered that really won't stand for it and start shrinking and threaten to die (e.g. N.hamiguitanensis). And most can take the intense and numerous hours of direct sunshine but again, some won't grow in it (N.ovata). N.edwardsiana doesn't seem to be in any of these categories so far for the couple of years I've grown it, so I would suggest it as a beginning HL plant actually. It does grow kind of slowly though.
BTW the best plants suited for the climate here all things considered are Trusmadiensis crosses. They grow slowly, but their pitchers don't mind the swings to 0 humidity for days or weeks at a time, so I get to keep pitchers for a year or two. The worst is N.flava.. I still haven't figured out its deal. Maybe it's the humidity thing. It's grown 2" since I got it... 4+ years ago.
Lets just say that all Nepenthes are great, and that each and every person has the right to grow the plant the way they want.
Everyone has their favorite, some species are more liked than others. (edwardsiana) The more people that like the species, the higher the demand. Pair this with supply and you get a price that suits most that desire the species.

I find it funny that most of the people here saying edwardsiana is super difficult don't even grow it.
There is a huge difference between growing a species from seed and growing an already established plant.
My eddy looks good after a few days I don't think it will be a problem to grow! Might try and get a larger one soon if it keeps looking this way!!!
