well i have this n. amp for a while now and it used to pitcher her and there about 3 months ago. now i have it in my greenhouse, about 65-75% humidity. i have tap water that sits out for about a week and i use that on all of my neps, most of them seem to be doing fine with it except for my rafflesiana. do you think it is the water i am using.? it is still growing, slowly and no pitchers are showing.
