Here's a suggestion from Rob Cantley of Borneo Exotics... He said to place the pot of heliamphora in a bigger pot. Use clay pot with no holes in the bottom for this. Fill the space inbetween with stones and bury the entire pot in the ground. Fill water into the clay pot.

The groud is cooler compared to the air outside and the water and stones will cool the roots. It is more important to make sure the roots are cool.

If you just got this from Choong aka kltower, then it is best to speak with him on his set up and how he cultivated this heliam. Then copy what he does because that's the conditions that the plant has been acclimatised to.
