    If your terrarium is pretty sealed up then you shouldn't need any humidifiers.

    Yes in nature when the temperature drops, dew collects on the plants. Personally I think wet plants in a terrarium is asking for trouble with disease, and running humidifiers to duplicate this is quickly going to rot the plants or kill the roots from overwatering.

    In nature the plants slow down photosynthesis as the sun sets. So cooling down and photosynthesis will drop in a gradient TOGETHER. In culture though it is different.. when the lights go out photosynthesis halts abruptly (unless there is a fair amount of natural light around still). I don't think it would hurt the plants to be cooled rather quickly. The faster they are cooled the faster respiration slows and the more energy the plant saves and can put towards plant growth.

    So what happens in nature isn't necessarily what is best or what happens in captivity. At least this is how look at the situation.

    Virus, If you can hit mid 50s most highland and some of the ultrahighland will be quite fine.

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

    Ok Parasuco, you must understand that these are only regular Ultrahighlands (the more common ones) IE: Rajah,Lowii,Muluensis. and they do not require a VERY cold temp drop like Villosa,Aristolochiodes,Macrophylla. They just require a routine 50ish temp at night. And you must of course remember that these plants are in cultivation not in the wild. And I realize that cultivized (?) plants have ancestry to there wild comarades but you still have to remember we have much more control over what they expierence than what the wild does. We can lower it to 55 while the wild only get to 58, as an example. All I am saying is that I do not think the time is important but the duration of the temp drop and if it reamains steady throughout the night. Please don't take this a mean conversation either. I speak from expierence, and what works for me and most other growers.

    I'm not taking us arguing offensivly... My rebuttle is from experiece of another grower, who got his info directly from John De Kanel, the Borneo Exotic's US representative...

    My terrarium stays fifty five all night... The amount of ice I put in (its not crouded, dont worry about me like, touching leaves, and freezing them off... [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img]), it keeps itself frozen, so when i wake up, there are still chunks... When I take it out, it goes up to wutever it wants to, usually 80 kuzof the light (not a shoplite, or anything special...), but if i c it going past eighty, i stick one bottle of ice to keep the temps steady...

    I thought lowii wasjust highland, possibly intermediate....
    I got this info from neps... Well, his wesite at least... Are you sure?

    Lowii, is considered an Intermediate Ultrahighland Which means it can grow as an Ultrahighland/Highland.Intermediate Nepenthes fine. So IMHO it COULD grow in a room temperature terrarium/ enclosure with no cooling for a while but in the long run should be in Ultrahighland/Highland conditions. This is all my opinion and how my Lowii grows,and it does very well in ULtrahighland conditions, but hey Lowii is an overall slouch when it comes to growing speed so you cannot make it go faster!

    Hmm... So one would live in my terrarium then?

    For it, and other highlands, CAN the temps go lower that that at night, for monthes at a time, without harm?

    Yeah it would be fine in your terrarium if it get's that cool at night.

    How cold are you talking about? Lower than what?

    well, before, when it was HOOOOOOOOT all day long and at night, by terrarium came down from eighty to sixty, but now its down to fifty five...

    I'm not sure how low it will go in the winter...
