The cool root issue is very much overhyped. As long as it is in a large enough pot,. with a high water table, it will be fine even in scorching sun.

How high do you keep the water?

glider14 would you give more details, i was under the impression that the cool root issue was critical? Hi, It was my understanding that the cool root thing was critical too. I have recently moved to Vancouver Island, but I was growing Darlingtonia in Auckland, New Zealand, where the summer outside temperature sometimes reaches 30C (I think it reached 32C this year in my absence. I had formed the habit of watering my Darlingtonia daily via sprayers in order to keep them wet, and trickle the water through the root system (in an 8" pot, in semi-shade, outside). However, after I left New Zealand, my partner wasn't so diligent. In fact, I am pretty certain that sometimes it wasn't watered at all, especially if she'd gone away for the weekend. However, I have photos to show that they survived (and thrived). Cheers, Bruce

Temperature/Light variations? Maybe they grow better with cooler temps? I unfortunately killed my account, when I changed my account stuff

Hey quogue,
Nice cobra's, I like the colouration you've got on these guys. Have you got them under lights or are they outside? It looks like the photos were taken inside.
An anwer of sorts to Alex's question on juvenile growth;
One of my cobra's did the same thing last year after the tip died off from thrip damage. The plant in question sent out about two or three new growing points all of which reverted back to juvenile growth, the strongest of which quickly sent out mature traps shortly after.
It was a fairly young plant, ie it had only been producing mature traps since the beginning of that growing season, so I don't know if this helps you any?
Also with regards to the root temp issue, I've found it necessary to place ice cubes on the surface of the pot during the hoter months of summer here in Perth, ie days will usually vary between 35 to 38 degrees with days in the low 40's during a particularly nasty summer. Temps like this tended to heat the water in the trays which the plants really didn't like. Days under 30 didn't tend to heat the water to a critical point.
Last season my cobras were infested with a particularly large number of thrip and really suffered, each time they tried to send out a new trap the thrip sucked the life out of it so the tip died forcing the plant to start a new growth point. I sprayed many times during the year which really only succeeded in stopping the thrip from killing the plants.
So I didn't really get to see the plants grow strongly, I plan to repot them in some new LFS this comming spring in a bigger pot to give them room with the hope they do better. Fingers crossed I can get the thrip population down to a less damaging number.
I will keep you posted on the results.
Dave.

I think these are my favorites so far. These are from California Carnivores.

Nice photo Trimen! Peter grows some Killer Cobras for sure!! The one I have pictures up of is from him.
The only way to answer your question JM is to look around all the nurseries and compare costs, size, reputation (you'll get a healthier plant from a respected nursery, might cost more though) and all that jazz...
Then you can decide for yourself. And I'm sure you'll learn a lot of other info at the same time.

My cobras are standing in full scorching sun and they are doing fine, I think that the temperature in the sun can get up to 35°C right now. The pots are in a very high tray, I keep the water level at about half way the pots or higher and they love it.
The root cooling thing is indeed a bit exaggerated, I think that it is more a mather of keeping the plants very wet when the temps shoot up.
