How hot is too hot ?

G'day Allen is live in Adelaide, South Australia and if anyone on here knows what our climate is like then you'd know we get HOT for weeks on end. It's not unusual for it to be over 35oC for 2 to 3 weeks at a time. We'll I've just bought a couple of little H. minors and was wondering what is too hot for them ? And would I be wise in freezing 3 litre blocks of rain/RO water and letting it melt slowly and trickle over their roots (i was going to do this with my Darlingtonia) to keep them cool ?
 
The accepted wisdom is to keep them below 30C, with their range in habitat being, daytime 15-29C and nighttime 10-15C, the lower nighttime temperatures are important. I've had them on occasion over 30C here in the UK for periods of a couple of days, but growing them in pure live Sphagnum helps keep the roots cool due to wicking and evaporative cooling due to the live moss. I have no experience of constant high temperatres I'm afraid.
Also I have no experience with using ice, I just don't like the idea, but I do have hundreds of Darlingtonia all grown in Sphagnum, and they have no summer or winter problems over here.
I hope someone who has experience of these temperatures chimes in.
Best of luck!

Cheers
Steve

I used in the past, ice water with a small pump for my darlingtonia in 100% live sphagnum. There was NO GROWTH and eventually, I lost the plant. IMO, it's too cold for the roots ?! Now, I use ice to cool the water and a pump during the hottest period of the day only. I do not have exp. about heliamphora.

Hi Coconut
Yes, although over here the sun isn't as intense over here, as it is in California/Oregon, so they don't burn or complain about hot roots, although for periods over the summer the pot temperatures do rise. I grow most of them in pure live Sphagnum, and the wicking and evaporative cooling effect that provides, seems to leep the plants happy.
