There's always someone there to answer questions, and the site is of much higher quality.

Congrats Carnivorousplants,

I would use just a couple at first and use a thermometer to keep tabs on the temperature. Add or take away bottles and adjust the distance the bottles are from the plant as needed to get the temperature in the range you want. When the temp is down to about the level the plant likes at night then keep using the number of bottles and distance you got the best results with. 2 bottles a few inches from the plant should get the ambient temperature down about 5-10 degrees or so from the room temp the setup is in for several hours. I have to use about 8 bottles touching my 5 inch pots in an ice chest to bring the temp down to about 40 degrees for the night. The water generally melts in about 24 hours or so.

You could also just invest in a small window unit air conditioner and set it very low at night for a few hours, placing the plant right in front of the air conditioner, but with a cover to keep it from drying in the cold air.

I keep having to remember to replace ice water bottles every 12-24 hours for my plants and it can be a pain until you get in the habit.

Hey!
my Rajah actually did good over the the night in that terrarium!!!
The one leaf that was damaged and wilted is now straightening out and the
tiny pitcher is looking a tiny bit bigger!!!hope it keeps growing like that and a
10 year old will raise one of the hardest plants to keep in a terrarium on a windo
w sill!
The other plants are obviously doing great since they are not as difficult as the
rajah.
Thanks,
Adrian

i wish you luck with your growing! glad your xmas turned out so great, and make sure to keep us updated with pics :)
