    Scholaty is it your latest leaf?
    If so it could be a few things. Have you moved it to a new location since the last normal size leaf?
    Has your temperature or humidity dropped since the last leaf?
    Have you watered less than normal?
    Are you growing under flourescents? If the tubes are over 6-8 months old they will have lost the bulk of their output. I am replacing all my flourescent tubes tonight as they are at least 8 months old. I didn't write the purchase date on the bulbs as I normally do so I'm not sure how old they are exactly!

    How big is your truncata and the pot it's in? Mine is 24" diameter but in a 6" plastic azalea pot. The roots are not yet visible from the bottom holes or in the top moss so it seems OK. I will probably repot soon but I don't see a dire need for it. The huge truncatas at Orchids limited with 4 ft leaves and enormous pitchers that vine endlessly through the rafters are potted in only 2 or 3 gallon hanging pots.

    Ahhhh...My bulbs are old...That could be it! Also, there was a dip in humidity, but only a little bit...so I bet it's the bulbs. Great. Now I have to go buy more supplies. My wife is going to shoot me. [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img]

    Hey Swords,
    Would you happen to know why my truncata suddenly produced a leaf that was smaller than the last one, along with a much smaller pitcher? [img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img]
    Do I need to re-pot?[/QUOTE]
    Hi
    Reading that reminds me of my N. hamata. This TC plant has grown steadily over the three years I have had it. But this year the current leaves & pitchers are smaller than last years crop [img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img]

    It was repotted last September and is not pot bound. The plant grows in my Nepenthes greenhouse where it gets filtered sunshine. Its been far hotter and sunnier this year (UK). Could that be a factor- too much light?? I am watering it daily and maintaining the humidity. There are no sign of pests and the leaves & pitchers despite being smaller look healthy & happy.

    Any ideas?

    cheers

    Bill I would guess it's due to the heat rather than more light. My hamata made a 20 cm pitcher in late may/early June and now the last two pitchers have been 17 & 18 cm but it is summer here and the tank is about 10-15 *F hotter than normal (up to 87*F during real scorchers and about 80*F the rest of the time from july - sept) so I suspect the pitchers will go back to nice sizes as the temps cool with fall coming. My highlanders seem to grow best with daytime temps no higher than 75*F, their best seasons for me are fall winter and spring.

    The only suggestion I could make is what I'm doing myself, which is increasing the watering/misting and air circulation (all while keeping the humidity at 90%+ ) when the days are warmest. Evaporating water cools the plant leaves and soil. If you don't need to lower the temps too much this seems to help. If you have a fan going make sure there's a source of humidity or the pitchers can dessicate quickly (esp. hamata).

    20 cm pitcher WOW!! [img]http://www.**********.com/iB_html/non-cgi/emoticons/alien.gif[/img]
    Mine are far smaller, even when they were bigger- if you see what I mean!!

    Certainly the heat is up, and I have moved the plant nearer to my rajah & villosa which are still getting bigger in size.

    How big was your N. hamata when you first got it? Over here in the UK, these kind of plants are always tiny and just out of TC, when you first get them.

    cheers

    Check out my newest N. truncata's pitcher! This beast is a whopping 1 ft tall, the peristome is 4 inches across and the pitcher is 3 inches wide. The plant is over 2 ft in diameter is is one of the steadiest Nepenthes to grow. The leaves keep increasing in size. I am thinking it will soon be a bush!

    Bill I think my N. hamata was between 5 - 8 cm when I got it in June of 2002.

    Dustin that's awesome! My latest truncata pitcher is still growing so I'm hopeful, of course you have a greenhouse...
