They seem to tolerate being grown in medium that is drier most of the time than one would normally keep Venus Flytrap growing medium. Heliamphora seem to die more quickly if kept too wet rather than too dry, is what I'm saying, just from my own experience.
My experience with Heliamphora is similar to Steve's. I have perhaps a hundred of them now out of tissue culture. The only ones I've lost have died because I kept them too wet and had them in media that held water for too long and was too dense (my normal flytrap media).
Lately I've been keeping them very, very dry. Much dryer than I let my flytraps get. They seem to be enjoying it. Their pitchers are thick and brittle and kind of remind me of succulent plants like the Aloe vera. They seem very resistant to drought.
Yesterday I repotted a large portion of the Heliamphora out of tissue culture. I have several dozen very nice looking H. minor and H. nutans that will be ready for sale in a month or so. Some of the H. nutans are quite large and many of the H. minor are already putting out adult pitchers.
One thing of interest that I noted while repotting them was that their roots grew often along the side of the pot, between the pot and the soil. I think that was due to the fact that the soil would stay too wet and that little cavity between the side of the pot and the soil would dry out much more quickly so that the roots wouldn't rot. I repotted them all into an "airier" mix with orchid bard, lots of perlite and lots of sand and relatively little peat moss. I think (and hope) that they'll like that mix better, though many of them seemed fairly happy in the standard flytrap potting mix.
