    I want to know how you Macrophylla turns out...Im going to try N.rajah as a windowsill plant I think. (I have about 50-60% RH inside)
    Need all the experience I can get...

    Hmm, i think that mac will be easier than a rajah.

    Hammy, is your evidence as an adult, or a juvenile plant like mine?
    Update: Parents convinced to allow me to keep greenhouse heated over winter. Most species will not be lost. Too lazy to update growlist.

    I still say it might do alright. People grow these rare highlanders outside and on windowsills with great sucsess. But please, tell us what your climate is like, and that'll help![img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img] What temps and humidity do you have?

    Well I friend of mine grows N.villosa outside here in sweden in spring,summer and fall. Its a little shaded and in a small greenhouse.

    He says it grows just fine.

    Our temperatures here in sweden is about 15 C day and 5 C night in spring, Summers can be very hot about 36C and 18 C night. I dont know how he manages that, In fall its about 15-20C day and 5-10 C night.

    My advice, don't do it, lol. N. macrophylla will not take kindly to adverse conditions with low light, humidity and whatnot. Be really careful.

    "What do I do if the growth point gets black, cut it off right?"

    You'd better hope and pray it doesn't get black, N. macrophylla is not a plant to "recover" at a young stage, its too slow growing.

    Hamish, why did your N. aristolochioides bleach? Too cold?[img]http://www.**********.com/iB_html/non-cgi/emoticons/new/confused.gif[/img]

    The aristo bleached because it got too hot. I have a timer on my extraction fan in the greenhouse at the moment. The timer fell from the ledge it was taped to and broke, thus the extraction fan didn't come on. I was out having my Sunday morning breakfast at a cafe, and it turned out to be quite a sunny morning. When I got home at about midday, I discovered that the greenhouse had become very hot without the extraction fan coming on at the apponted hour. Whilst the lowlanders which are kept in hanging baskets high up to get the heat loved it, the aristo, which are kept on a lower shelf, did not. Several had the growing tips a bit broiled, and the new growth is bleached and deformed. Several ramispina which are kept up with the lowlanders got really roasted, and all the old growth is crisped, but they were subject to much higher temps than the aristo.

    The deformed leaves on the aristo should grow out after about 4 new leaves, but it has ruined the upper pitchers that I was hoping to take photos of for my website. It'll now be several months before I have good quality uppers (assuming they keep pitchering during the summer heat - it's still late spring here and already the nights are staying a bit too warm). I think aristo is particularly sensitive to high temps partly because it is from much higher elevations than most highland species, and partly because it is so gracile. Lowii and macrophylla, which are big, chunky species, don't seem to sulk so badly with the odd hot event.

    TyFone, growing villosa in Sweden would not be much of a problem, I'd think, as it is a cool climate country, certainly much cooler than most of Australia and the Southern parts of the US like coastal southern California. Most highland species, even those ultrahighlanders like villosa and lamii, will cope with 3-4 months of warm weather if the rest of the year is ideal. This game is all about the law of averages.

    Hamish,
    I would say "lucky" to have your sources and get seed of so many rare species-if you can keep up with the greehouse space, you will have a plethora of genetic material for whatever purposes you want down the road.
    Your comment about "law of averages" got me thinking: Most people who cool, I assume do it for the whole night period, but if you are using a cooling unit, how little a time period at that 45-50 F(or whatever your low) do you think you need? If the plant is at that temp for only an hour, does that fit the bill?
    Just wondering..

    Cheers,

    Joe
