    Red face

    I have had my nepenthes ventricosa for about 6 months. It was a bare root plant with 4 leaves when it arrived. Currentally it has 10 leaves with more forming in the center.

    For some reason it's leaves have gone from a dark green to a yellow-green in color. The pitchers are on the leaf ends but none have developed.

    The temperature goes from 80 during the day to 75 at night. Humidity is 50% during the day and a bit higher at night. My plant is in a 10 gallon fish tank with four 20 watt florescent bulbs on 13 hours a day and aluminum foil on all sides of the tank.

    Any suggestions on what to do?

    I think maybe your temperature is a little high, either that or their is some root rot from stagnent water. Also, I've found mine pitchures more with less light.

    How are you watering your plant? Nepenthes do not like to have wet roots for any long periods of time.

    Careful where you crawl, it might be a trap!

    The biggest problem you have with your plant is temps. N. ventricosa is a highland not a lowland. The day temps should be 75*F, and th night temps 62*F-67*F. Also the humidity should be around the 67%- 85% or higher it would make the plant really happy. What kind of lighting do you have? Also do not have neps in standing water. The neps that like a lot of water would be N. amp, N. Bica, and N. x coccinea etc etc . Have you feed the plant lately? Plus your lights should be turned on 15 hours a day. If you have a Hygrometer check what the humidity is during the night, do the same with a Thermometer.

    Things you can do to cool your 10 gallon tank (at night).
    1: Take frozen bottles about 3 and place them around the plant. I doesnt matter is you dont putdistilled water into the bottles as long as you don't have any of the water go into the plants soil.

    2:If you have more then one highlnd nep in your ten gallon take reuseable cups and put ice in them.

    Have Fun,

    if the plants were in the basement with highland temps then there wouldn't be a problem. Since she says that the temps at night are 75*F that doesnt sound like night temps in a basement. [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img]

    Hi all:

    I have an issue with N. ventricosa. mine does not want to pitcher in winter time. temps during the day are about 75-80 F and at night go down between 45-55 F. I don't thing that the cooler temperatures might have an effect on this plant, but i think they do. my ovata, veitchii highland, and couple of other highland hybrids are pitchering under these temperatures. the question then is, is ventricosa a real highland?? or maybe it is an intermediate. If it comes from the philippines, how cold it gets there?. Truncata comes from the same region and it is considered a lowland. However, there is a truncata variety which is a highland!!. Any ideas??

    Gus
