i think if you touch dry ice with your hands you will get burned. so i you buy it make like a wire rack and put it ontop of it and have it hang into ur terrarium. you can get it at a gas station place. im not sure if trhey still sell it. it lasts for about a week or 2 in a cooler. maybe a week in ur terrarium. im not sure how much it usualy costs ill go look on google
found some stuff.
and it is about this cold. -109.3°F or -78.5°C
maybe a bit TOO cold [img]http://www.**********.com/iBhtml/non-cgi/emoticons/tounge.gif[/img]
its about a doller per pound.
on that web site click where to buy dry ice and type in your area code number, the kind for telefone. like mine is 954 for florida. just type in urs.
goto www.google.com and type in dry ice and find soem more stuff if ur interested
and it dosnt melt. it Sublimates. that means it goes from a solid to a gas. i dotn think dry ice will work. it is too cold and the fumes may kill it

Pretty neat stuff. I may not try it as of the cautions. I think I need some more ideas please.
Hmmm... it's been a long time.. but I thought dry ice was CO2? perhaps its gasses would be beneficial...
but yeah, I think that is going to an extremem guys.
Well it is CO2. But it is extremly cold! I thik I'll skip that I don't want it freezing in there! But, how do other N.Rajah growers cool it down? In a terrarium?
The only person I know who has successfully cooled his plants down in a high'tech fashion, uses one of those coleman protable coolers with a glass top instead of the normal one. He has the power running through a thermostat, with the thermometer in there with the plants... when they get warm, it kicks on...
HEY RP~! that guy is on garden web. he asked how he could do it and he said he had THAT coleman 40 qt. cooler.
i read the thing post, How to cool a terrarium. and i think taht is the best idea. but where to geta thermometer
what about placing your terrarium in a cold room and heating it during daytime ?
That's what I do.
Durng winter nighttime temperature is about 15°C, during summer 20°C.
I tried an ultrasonic-fogger combined with a PC-fan (at lower voltage) and with this setup I can get 1-2 °C lower than room temperature.
I tried a peltier-element (the one in the cool-boxes) on the top of the terrarium without great succes. Maybe 2°C less.
Another possibilty I'm going to try is a electrical cool-box which can cool down water to about 5°C and than let this water circulate to the ultransonic fogger and get cold fog blowing through the terrarium by a small fan.
No experience yet.
With my conditions at the moment most highland plants do well, (hamata, veitchii, inermis, lowii,...) but the rajah is really slow and still very small.
A picture of it :
Cool Martin! I like the pic. I think I found a nice hit. I was looking through a magazine and found a minature evaporative cooler!!!!!! I also may try a cool mist humidifyer and I may try more ice at night. Thanks. Nep.G.
