Mine seems hardy... Never thought of it being difficult much. It finished growing a leaf and opening it in my care and it is starting to grow a new one. The pitchers seem to last pretty long too. Its media has been kept pretty wet to keep the sphag on top from drying out, since its in a greenhouse in the middle of summer.
It has been growing in 50F nights and around 80F days. Some days, it has gotten to around 95F and none of my highlanders, intermediates and lowlanders seem to have any issues with my conditions. They continue to grow and pitcher quickly. 80% humidity morning, 60% humidity day, 80% humidity evening, 90% humidity night.
