    Not that expensive, it's about a dollar per pound

    They carry it in Harris-Teeter of all places! Around a dollar a pound if I remember correctly. They receive it in five pound blocks, but it sublimates in their freezer. Find a smaller block to start with, you pay after they weigh it. The trouble with it is keeping it from "melting." It doesn't keep in freezer too well.

    I've seen people talk about using it for camping. Supposedly they duct tape the cooler shut with it in there, only going in it once a day. It keeps stuff frozen for several days like this (in the desert!) In that same vein, I've heard not to put dry ice into air tight containers as it will still melt causing a pressure increase inside the container until it explodes.

    Maybe a bit too complicated for everyday use, but a good excuse to play with dry ice!

    You probably wouldn't need to -- that is, if you have a terrarium set-up. Just place gel-ice packs into the chamber and re-freeze them during the day -- less trouble than dealing with pets.

    Luckily, in Northern California, I do very little to maintain my highland plants, since it's almost always in the low fifties or upper forties at night; but when I lived further south, near LA, I did the gel ice routine -- a bit of a pain at first, but far better than losing sometimes irreplaceable plants . . .

    Yeah that's a good idea, my only worry is that the ice pack won't stay frozen the whole night. I'm also currently experimenting with ice cubes to see how long it lasts and how cold it gets.

    yes i grow an N. rajah, and im pretty sure David (BigBella) got a rajah from me some time ago....its quite picky and does not like lowland temps at all.....so far mine seems to be doing rather well for a change though XD

    there are several others on here who have a rajah, its not a rare plant, just hard to grow...
