    Immature Blackening Pitchers

    I noticed the undeveloped pitcher on it right now seems a little dark(black) on the tip. what could cause this? is it too late for this pitcher?

    My days temp is 69 F
    night is 62 F

    humidity is 100%

    i've sprayed the terrarium but never watered it

    Soil/Substrate: Sphagum Moss and Coconut fiber

    Hours of sunlight: 9 1/2h

    It is the humidity. Very high humidity all the time will be harmful as it will make your plants vulnerable to fungus and your plants will become fragile. What plants are you growing? No nepthenes needs this kind of humidity. I am growing a hamata with lows of 20% humidity.

    The terrarium could also be overheating when it is in the sun. Try and move your plants out of the terrarium. Many plants are a lot tougher than you expect.

    My terrarium is usually 99% from late afternoon to morning 7am, When I come back home at about 4 it's down to 87% Humidity, is this till too much, i'm scared for my plants now, there is this huge pitcher thats been inflating for almost a month and hasn't opened yet. Is it normal to take that long? Its about 7cm tall.

    Correct me if I am wrong, but highlanders are more tolerant of (and accustomed to) a humidity increase at night. I doubt that the humidity will kill the pitcher, especially since it has one month's development behind it.

    What Nepenthes is it? Could it just be some normal coloration of the pitcher during development?

    Highlanders do indeed appreciate high humidity, at night - but constant 'round- the- clock high humidity isn't good for them for reasons listed above. In their natural environments, they will experience a drop in humidity during the day as temps rise, which also increases air movement (wind).

    It's a highland truncata, and I highly doubt it's a "black-tip" truncata.

    Heh. I only said that because your original post was ambiguous about it being "dark(black)." I was leaning more toward the dark side, but I get your point. How long have you had the plant?
