The leaves on my darlingtonia are starting to shrivel and die and I donít know why
The plant gets plenty of light, high humidity and a cool root system
So what could be the reason of that?
Is your plant inside or outside? If outside, I would check for parasites. Also, where in the world are you? Or is your plant near an AC vent? Darlingtonia require dormancy, so if it is somewhere that it is chilly, it could be fooled into thinking winter is coming...
the plant didnít get its dormancy this year
and i grow it in a terrarium with my Heliamphoras for several months.
up until now it grew really good. it made beautiful red pitcher and now its starting to dry and shrivel.

The lack of dormancy is probably a contributing factor. Also, Darlingtonia do best as an outdoor plant, similar to that of VFT's and Sarracenia. But don't just stick it outside. It needs to be acclimated, if you should decide to put it outside.
