Hai, recently i was out of my mind and bought this little fellow, here come a question, can u all guess how much this cost??(Sorry, no price for the winner

)
If not mistakenly calculate, there got at least 3babies(4actually, but shoots rot already) and 3 mature plant together

see, small shoots coming out from the not-producing mature plant
One more picture trying on air propagation method

Hoping this one will success at last....huh
But i was curious that why that stem of the plant did not produce any pitcher at all, i was found out that there were a scar(because someone bend the plant) and the another baby stem come out, could this be the main reason why the plant did not producing any pitcher at all?

Kindly ask for any pro for answering my question.....
What medium should i using for this plant and what should i notice or have extra attention on it?? THanks!!!
