    The plants should cool off fairly rapidly once the light goes out. That way their respiration slows rapidly also. In the wild they are cooling down fairly significantly as the sun begins to set....

    My chemistry is rusty and I forget the term. But basically air is does not have the ability to store/release large amounts of energy(heat). So it would require large volumes to absorb all the stored heat in the terrarium and heat entering the terrarium through the glass once it starts to dip below room temperature. Before you go crazy with more air pumps, insulations etc etc.. You should think about the cooler that coleman makes. It will run on 12v or 120v ac. I think it is a 40qt cooler for about 50 bucks at walmart. Replace the lid with a piece of plexiglass and place it under 3-4 tubes of light. The only tricky part is wiring up a thermostat/timer so that it can be set to hit 50-55 at night instead of running continuously for chilling drinks.

    Interesting topic.

    I'm in pretty much the same situation as you Ram and until now I have not tried many highlanders for the same reasons.

    The fridge on it's side with a perspex lid idea appeals to me but I don't want to have to run it 24/7.

    Am I correct in thinking that for many of them (same as Ram - Rajah is not my dream Nep, I want to try dubia) will tolerate almost normal lowland temps in the day as long as they get it nice and cool at night?

    Cheers, Troy.

    I have found most highlands/ultrahighlands to tolerate fairly warm temps during the day. As long as humidity and air circulation are very high.

    With my current set up the under bench misters click on around 82-83 degrees then the vents open around 85 degrees and the first exhaust fan clicks on around 86-degrees. There is a second exhaust fan that will activate around 88degrees. MOST days only the one exhaust fan is running.. which means the temps run between 86-88 although on a really hot summer day both will be running so temps are getting to the high 80s-low 90s. The key here is that the under bench misting clicks on before any of the exhaust fans and runs continuously and is the last system to click off as temps cool down at night... There is almost a fog of fine mist floating around the highlands during the day when the system is operating. Actual plant temperature is probably a little lower then the temperature registering by the thermostats.

    My next system will be evaporative cooling pads however. This would allow for much less water usage and cooler air temps then I can currently achieve.

    bottom line... mid to upper 80s with good humidity and air circulation. 90's are iffy and risk losing plants

    I think you would find it fairly economical to run a fridge/freezer on its side. With a setback thermostat you could set it for 80 during the day and 55 at night and your probably only cooling to 15-20 degrees below ambient temperature. With a well insulated fridge it probably will not run all that much. Maybe Jeff can add more with regard to this.

    Running a fridge for 24/7 should not be a problem at all. The key factor is the very good insulation of the system. For plants of course warm day-temperatures are needed which can easily be reached by turning the fridge off by day. If light is powerful enough and the thermal capacity of all materials inside the fridge are low, the temperature will rise in short time. Risk of overheating is high in such a good insulated system, so using a fridge with two different thermostats set up for different day and night temperatures would be ideal.

    Avoid using those small fridges with peltier elements designed for use in cars etc. Peltier elements do have a horrible bad efficience. Normal fridges are already very good insulated and they can easily made better by increasing the insulation with a layer of styrofoam - I suppose you won't set up such a system in your living room...

    The temperature range Tony mentioned above, does match my experience and is suited for most Nepenthes - well some ultrahighlanders may need even lower temperatures. Nepenthes like N. bongso or lowii will already be happy with night temperatures of about 55-60 degrees.

    well, I think I am going to continue with this experience for now, simply because I already own most of the material being used, and I am quite sure it will be years before I any plants I buy will be big enough to warrant the size of even a small refrigerator...

    it is certainly a more ideal solution... but I am trying to do something really inexpensive here with pre-owned equipment that requires very little modification... I just don't want to get into wiring thermostats and such at this point...

    besides... this is kinda fun... I like experimentation! [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    Daytime temp with the shades closed today, is holding at 80 degrees, so we are doing a lot better today without the sunlight filtering in... of course, I think the tank is not getting enough light from the two lamps on it, so there is still some adjustment to do...

    Anybody think that two tube 24" fixture will provide enough light for judith finn?

    I use a 2 tube 24" fixture on my Rajah,Lowii,Hamata,Burbidgeae,etc. and they are all very happy with it, yes I would say enough light. [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    Thanks hoss!

    What lights do you have in it? standard col white soft white? plant bulbs?

    I have one cool white and a plant bulb right now, but I am going to go for a cool and soft white mixture when I go to HOme Depot this week.
