I have grown them before and I just ordered both live plants and seeds.
I have only ever started with live plants, but here is how I was VERY successful with them;
Think terrarium... I got a cracked 10 gallon tank from a garage sale, filled it about 6 inches with a mix of farmpond muck, backyard dirt and left over sand, all just poured into the tank and mixed with bare hands, and planted the Lowes or Walmart bought PP Plants like any other house plant. I then covered the top with a rusted old cookie sheet and it made a not quite airtight seal, and set it on a TV Tray right by the sliding glass door that got TONS of indirect sun but ZERO direct sun. I the simply kept it so there was a constant condensation on the glass, and fed the pitchers a NON-POISONED bug every couple of days (from the bug zapper catch tray).
I soon had enough to split out and pot up separately if I had wanted to. That is precisely what Im planning to do as soon as my orders arrive, but this time I will harvest the mature plants and 'get' the extract from them (once I learn how to)
PS, I also have a shit ton of extract that I ordered over a year ago when that piece of shit Gates first uttered the words Small Pox. So growing my own is planB
I care not
