    How do you guys think it will hold up? My temps are usually correct in my room, and i think that mac is more humidity tolerant than given credit for, as i've grown it for a while.

    I can't keep it in the greenhouse for reasons i won't explain. So i guess i'll have no choice. I'll keep you posted!
    Update: Parents convinced to allow me to keep greenhouse heated over winter. Most species will not be lost. Too lazy to update growlist.

    It's certainly possible. Just depends on your climate. If I could keep the humidity here above atleast 50%, I'd try a macrophylla.

    Tuna-

    As a young plant your N. macrophylla will be more tolerant of less than ideal humidity, temps and light. But be forewarned that this is only a temporary stage. As your plant matures it will be far more demanding of conditions that are similar to its natural habitat. Many highland Nepenthes species are easier to grow as babies and juveniles but can become extremely challenging and intolerant of those same conditions when they get older. Your dealing with a very high elevation plant that likes very cool and very humid nights. Most true highland or ultra highland montane species have strict condition requirements that are very difficult to duplicate on a windowsill.

    I'm not trying to burst your bubble or steer you away from this project in any way. You have a VERY valuable and rare species and all caution should be exercised. I live just south of you so I know what our summers are like. During the fall, winter and early spring you should be ok, but keep a close eye on it for any signs or a crinkled or reduced growing tip or pits and creases in the newer leaves. That's a sure sign of stress and if not nipped in the bud immediately it is irreversible.

    Much luck to you with your plant. Keep us posted through the months.

    Tuna,

    Macrophylla is not a toy. Do not be decieved by tolerance as philcul mentioned.
    In reality, I would try to steer you away from this project. Why not start another project. i.e. buy a portable fridge and convert it by adding a fluoro light. They only run on 12Volts or a car battery. At aquarium shops they keep brine shrimp and blood worms or mealworms in them. If you really want to keep it alive I would try that. On a windowsill for that species is like playing with fire. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    P.S. Same with inermis and villosa should you get one. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    Cheers,
    Christian

    I think Neps Around The House has grown N. macrophylla outside in Southern CA for at least three years, so they are probably fairly tolerant of low humidity. I know from personal experiance that it gets extremely dry here in the summer, but we do get fog and bigs drops in temperature at night.

    Yes, i have found some plants to be tolerable of more than most people give credit for, but why will it get more intolerant over time?

    I'm not able to keep the macrophylla in the greenhouse, as i stated earlier, and converting the fridge is out of my budget. Maybe i'll try my luck with the remains of my greenhouse once it gets older.

    So, if it starts to get black on the top of the grow point, i have to hack it right away?

    My rajah and lowii are still intact, is it the same story with them?

    EDIT/UPDATE: I am now able to keep my greenhouse up for reasons i have explained elsewhere. I will still keep my mac here to test how it does, and move it to the Ghouse if problems arise.

    There is anecdotal evidence that seedlings of highland species are more tolerant of less than optimal conditions than mature plants. I don't know how much of that is based on empirical observation and how much is "passive subjective empiricisim", i.e. casual speculation.

    In my view, macrophylla is not the hardest species to grow, certainly it's no more difficult than lowii, maybe a touch easier. It will tolerate warmer than preferred nights for months on end, although it does require cool nights for at least part of the year to grow well. It obviously wouldn't grow well in lowland conditions.

    Like most highland species, it will tolerate low humidity, with varying results. Sometimes it will pitcher well, sometimes produce small pitchers, and sometimes fail to pitcher. However, leaf growth should be steadily larger. If it's not, then you know your experiment is not going well.

    I would say that if you can get hold of a not-too-expensive TC macrophylla, go for it. It certainly will be easier than trying to grow villosa, lamii or even aristolochioides in similar temperatures. I had a greenhouse incident a few weeks ago where temps got into the high 30s and maybe the low 40s for a few hours. Whilst the lowii and macrophylla were fine, several of the aristo had marked negative reactions, with bleached leaves and deformation of the growing tip.

    Cheers,
