    Just be careful on pumping in all that dry AC air. What you need is a humidistat in the tube and the ultrasonic humidifier connected right after the AC unit.. then you can have 55 degree air at 80% relative humidity!

    So it would be best if the mist and AC air blended in the tube before the enclosure not once it gets into the enclosure? That should be easy enough, just cut a hole and tape the humidifier output in at a "T". I have experimented with it a bit already (just sticking the tube in where I hook the vent & hose to the AC output but what I dislike is the fact that when the humidifier and AC are blended in the tube I can't see the fog as the air exits the tube, so to me it's "not working" even though the tanks humidistat says 75* and 81%.
    Is 80% or so high enough humidity for these nepenthes?

    80% is plenty high enough. Personally I would say yes it would be better to premix them. If it is running correctly you shouldn't see mist blowing from the tube as this would indicate near 100% humidity. It is just my opinion that you risk zapping the plants with cold dry air otherwise. The humidity level in the AC air is probably down near 20-30%.

    The only problem is that you won't also see if the humidifier is not functioning properly with it connected upstream of the terrarium.

    Yep, right-o Tony!
    I hooked it up with the AC vent & duct hose with humidifier's hose going into the duct hose about 4 feet before the enclosure and last night I achieved 57* and 86% humidity at about 4-5 AM (and it was HOT last night&#33. It just makes me crazy that I can't see the mist when it's hooked up this way but as long as it works - I guess I don't care about seeing mist (I do like the look of a foggy terrarium though)! Today the terrarium is 84* and 82% humidity.
    Did you say to not let it get much higher than 85*F or is that only important if the humidity is low that daytime temps over 85* will matter much? I do have the fan blowing on the front & sides of the enclosure most of the time and it usually stays around 75-80* but it's been hot & humid lately and will be til about late september here in Minnesota so everything is at a higher temp these 4 months in the summer.

    They can take over 85 .... my greenhouse gets up near 90 on a sunny summer day. However, there is a misting system and exhaust system. So the air is fresh and moving. I would say that much over 85 in an enclosed terrarium could be risky even with fans blowing the air around because your lacking the fresh air exchange you find in a big greenhouse or out in the wild.

    It's just a matter of getting to know your setup and the plants and how they respond in your situation. If the pitchers lids start drooping then you know something isn't quite right. Otherwise they are probably fine.

I am out of ideas and need a better setup, ice is OK for winter but not summer!!! I found that out today. Any ideas or websites with MINI AC's? Thanks, also Tony- got any ideas?

    Nep G,

    I don't know about mini-ACs, they sell chillers for reef tanks but those are horribly expensive ($600+) whereas my tabletop/window AC from Home Depot was $118 ($124 with sales tax) It works just fine for the room and the terrarium together. If you wanna see how I got my setup, setup click to:
    http://the-natural-aquarium.com/highlandterr.html

    This page is mainly info about how I'm chilling it now how I built it or any of the other features. I need to update with the larger input vent and the humidifiers new hookup someday I fix up the page. Right now I'm thinking "patio greenhouse" for my condo... I wonder if I'll get away with it!?

    Nep g,

    I've been looking for mini-Ac's for a while now, and I haven't been able to locate anything useful. There was one place that had a cooling device with a peltier (supposed to be super heavy duty), but I think that they are very expensive. Anyway, I was talking with my mother about this (she asked why I had so many bottles full of ice in the refrigerator ) and she said that I might try getting a ice box compressor and modifying it for my terrarium. She says she knows a guy that buys replacement part for refrigerators that might know how to set it up. She also says that it might not be too expensive. Just a thought.
