    Aaron,

    I see four leafs on the vining stem. You can count the lower two to the transport / adaption shock, they might not develop pitchers at all. For the upper two-and-a-half leafs there is still hope. The pitchers need quite a bit of time to develop. Try measuring the buds every day, maybe you can see an increase.
    To add one more theory [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img] Maybe the vining is indeed a physiological reaction to the transport shock (also I haven't found this in literature yet), like you find a sudden flowering for some Neps after cuttings are taken. Speaking of 'shock': It sounds like you are in the temperate climate. Isn't February very cold month to aquire a Nep? Maybe this stress (be it just from your car to the house) 'switched' your Nep into vining mode? Then again, maybe it is just a cooincidence.
    Light might be also the factor, if I was a plant, I would also grow taller to receive more light. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img] How short are your days in winter? Then: if it was, wouldn't it be a well known fact to growers?

    btw, my albo leafs are also green and so is the one of the Penang-picture above.

    OK, another VERYYYYYY long post by me!

    Tony,

    No Neps generally just so seeming instant from non-vining to vining. In the case of this plant at least it seems like such a quick change.

    I concede, at this point, that that is about my only option.

    Many nurseries grow their plants soft.. ie lower light, higher moisture, heavy feeding. This produces larger plants quicker. With Nepenthes however this is of little value except for them to list nice big plants on their pricelist. Some nurseries are better than others. Properly grown plants will experience little setback and adjustment period while those pushed into large soft growth can experience a very nasty longterm adjustment period.
    I have been led to believe this is the case with a/some local growers but I do not know about the supplier of this plant. Admittedly it does not bother me much as I have been VERY impressed with the size of some plants I received recently. However, I have noted that they do seem more prone to an initial shock response.


    Volker,

    Yes 4 fully developed and 2 new forming (you can just make them out as one is opening/unfurling and the other is just a 10cm long spear).

    All of the leaves on the vine section have developed since in my care though as Tony noted, the growing tip does appear to be vining already in the earlier picture.

    'm not actually measuring (I do check every plant and every undeveloped pitcher morning and night, on my way out and back from work) but is does appear that the newer leaves have a slightly longer tendril. Though, it is hard to tell as the leaf unfurls from base to tip and it is the pitcher end that widens last, revealing what the pitchers will do. The pitcher buds do not appear to be swelling but they do seem viable and alive, as mentioned earlier. Plus each new leaf SEEMS to have a slightly better developed pitcher bud.

    Temperate to cool climate but with HOT summers. Winters rarely go below 0C (current lowest this year is about 3C at my place but the average is still around 10C) and summers average say about low-mid 30C with occasional high days in low 40C.

    Note that my glasshouse is AROUND 15C night and 25-30C day, as mentioned in more detail earlier..

    We are Southern hemisphere so February is mid/late summer with long days and hot weather. In fact at that time of year I am still combating heat and trying to get the nightly temps down to suit the highlands/intermediates.

    Quote Originally Posted by [b

    As at today sun-rise 7:20am and sun-set say 5:12pm so day length is 10 hours. However, I am getting about 6 hours of direct sun on the glasshouse at best. We are 3.5 weeks from he shortest day of the year so I would expect that timeframe not to go below 5.5 hours at worst.

    As for the " well known fact" I donít know. I'm pretty new back into CP's and am going through my first set of seasons with the glasshouse. I can't compare to other growers as I have not caught up with many form the local society yet, but I can compare to the other Neps (25-30 specimens so far) I have in my collection. I have mostly highland/intermediates with a few lowlands (Raffs, Truncataís, Amp, etc). All other Neps are still pitchering other than an N. ampullaria (which is another issue).

    I know that speaking to a few other local Nep growers they seem to have trouble with lowland plants in general, though I believe I am the only one that is heating their glasshouse.

    Given all of the great options and feedback that has been provided here I donít know if there is really much I can do other than hold off, be patient and see what happens. As I said, the pitcher buds (newest 3-4) seem still viable.

    Thanks,

    Aaron.

    Hi Aaron,

    from my experience N. albomarginata needs some time to establish to new conditions. I had a plant few years back which initially also refused to pitcher. After some months pitcher production resumed and the plant produced a pitcher on every leaf. Under my intermediate to highland conditions N. albomarginata was very slow growing, so I am surprised by the growth rate of your plant.

    Some additional artificial light might help your Nepenthes to grow better during winter. A total of 12 hours of light should be fine.

    Cheers Joachim

    Thanks Joachim,

    Unfortunatley, I am currently running almost 1,500W (not including pumps and heaters) of lighting over my marine reef tanks (another 600W of lights coming online with a new tank soon) so in order to keep my electricity bill from becoming even bigger I'll just have to tollerate the slower growth until the winter ends and day length increases.

    Aaron.

    UPDATE:

    Good news!

    Joachim, looks like you called it on your last post with regards to settling in time with Alboís. Although no full pitcher just yet, the oldest well formed tendril has slowly elongated and the pitcher bud is starting to swell and form a more pitcher-like appearance.

    If you look at the latest picture above, it is the second fully formed leaf on the right (after the vining has started and is pointing towards the green Maxima pitcher) that is swelling. Since that leaf the plant has produced 4 or 5 new fully formed leaves, there is a half-formed leaf unfurling and a new leaf tip. They are ALL forming longer tendrils and are starting to swell their pitcher buds.

    So that's my good news [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img] and it looks like only a matter of time now.

    The interesting thing is that this is one of my oldest plants, yet is the only plant I have that has not yet pitchered. Sure was testing my patience!

    Aaron.

    UPDATE:

    I think I'm in love [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]

    Standing about 7-8cm (3") with the next looking as though it'll be bigger.







    After all that worry.... ABSOLUTELY worth the wait!

    Plus I am doubley happy having sourced myslef an all red form and speckled form today. Should have them by weeks end.

    Question: What's about the maximum pitcher size for Albo's? I'm quessing not much more than about 13cm (5")?

    Aaron.
