    I've had my Albo for a bout 3 months.

    It was purchased as a rooted and growing cutting with about 6-8 leaves and no pitchers. It is vining quite rapidly and has added 5-6 leaves and about 30cm in height.

    However it is not pitchering.

    Although I am not completely discounting it, I feel that light is not an issue as all other Neps are pitchering just fine. Does Albo need more light than most other Neps?

    Humidity is mostly over 80% but there may be short periods of say 15-30 minutes where the humidity CAN drop to 50% on hot days in-between spray cycles. I have plans to fix this by removing the spray timer and adding a swing-arm moisture sensor.

    Temps are intermediate’ish with about 15C (60F) nights and 25-30C (77-86F) days.

    Any ideas why it's being so stubborn to pitcher yet is still growing very rapidly or is there a clear issue with my parameters that I have missed?

    Thanks,

    Aaron.

    Hi Aaron,

    I am growing albomarginata outdoors in the Philippine lowlands and it has no problems pitchering (whereas N. rafflesiana for example prefers waiting for the rainy season!). Although this location might sound very steamy, we didn't have rain for about 4 months and humidity dropping down to 40/50% during the day, combined with strong winds.
    It might receive 1-2 hours of full (!) sunshine, aside from that it is shaded by other objects, still the indirect light might be quite strong.
    It gets six times a day irrigated for 4 mins each.
    Now, what's the conclusion ? [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]
    It's probably not the humidity, which is always suggested when a Nep is not pitchering. The mayor difference in our growing conditions is the night time low, which is only 24 deg celsius here.
    If that's a reason not to pitcher? I don't know.
    Maybe one day it will just surprise you and pitcher anyway. The pitchers last quite a bit, which is nice.
    Happy growing, Volker

    Mine pitchered well when kept in lowland conditions. I would suspect that the nighttime temp is your problem. Generally speaking, it can take a lot of light. Mine gets a couple hours of late afternoon New England sun and seems to like it.

    Aha! Mine isn't pitchering either! I think it may be time to replace the bulbs!

    Thanks guys.

    Volker,
    Interesting thoughts on the humidity. However, (as you noted) the more I think about it the nightly temp drop does seem to be the biggest differential between my conditions and those that are doing well with Albos.

    The interesting thing is that I have 3x varieties of Rafflesiana, all doing well. They are not the fastest growers but all pitcher nicely when they get to it. I also have 2x Truncatas which perform about the same as the Raffs.

    D,
    I'm getting about 6 hours of direct light now depending on the weather/cloud cover. I'd not expect it to get much less than that as we are nearing the shortest day of the year. It's not direct sun as I have the glasshouse lined with a layer of thin bubble wrap. However, the light is enough that I do get substantial reddening of the leaves on quite a few of my Nep species.

    Unfortunately the lowlanders are in the minority and I'm not inclined to adjust the temps specifically for them so I'll just have to see how the Albo goes... OR save my money for a second glasshouse [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]

    Aaron, I think you have a good handle on it, but I can relate my experiences. I have a N. albo "purple" that has pitchered on every leaf it makes, and does so rapidly and regularly. It is in about 60-80% humidity, and daytime temps of about 78 degrees, and nighttime of 63-65 year round. This is fairly close to yours. The only thing I can think of is that yours seems to be a lot taller, my plant has new leafs right on top of old leafs, and no vining at all to speak of. Perhaps yours is vining, and is reluctant to pitcher because they would be uppers rather than lowers. This could be totally off, but it's all I can think of.

    Interesting thoughts there Caps. So it might be putting it's energy into vining as opposed to pitchering!?

    This theory could also explain why it had no pitchers when I got it from the grower. If it is common behaviour for and Albo to not pitcher while vining and this was a cutting from a vining plant, then that MIGHT be an explanation.

    Does anyone have a 'vining' Albo that is still pitchering?

    I'll post a picture tonight to show just how fast this thing is vining. At the moment each new leave is at least 5cm from the previous and they are getting further and further apart with each leaf.

    BTW, this is a green form.

    Aaron.

    My N. albomarginatas pitcher while vining but more on and off than with every leaf. Try giving the tendrils something to grasp or let them trail into the surface of something. Some Nepenthes don't seem to skip a beat when they hit vining phase others are real bears to make pitchers, even under ideal conditions.

    Tony
    Is that a Nepenthes in your pocket or you just happy to see me?
