Good to hear its doing well for you still Halt
Bob, You would be better off growing darlingtonia outside, and as...who was it earlier that said it? too lazy to go back, the mountain variety is a bit difficult to get your hands on. Mine is proving to be insanely easy, A because its the mountain variety, and B my climate is exactly the same as it is in their natural habitat a couple hundred miles southwest of me XD.
Id personally grow it outside, flood the pot with cold water daily on hot days, or even put icecubes ontop of the media.
Media, id use 50/50 lfs/perlite or 100% pure live LFS....either one works, the perlite just aids in air and reduction of soil compaction so its really a matter of preference. Ill see what i can work out with divisions on mine again, Maybe ill be able to find something out for you to get you the mountain variety
Edit: Also bob, there is really no difference in looks between the two, occasionally the mountain variety will get a kind of red blush to it.
Also, the mountain and coastal are the same plant, just one originates from a higher elevation. Lets not forget the 'othello' which is known to be completely red IFRC
