Hi!
To my understanding, certain Nepenthes species requires different daytime/night time temperatures depending on their natural altitudinal distribution. Can anyone explain to me what would happen if I didn't provide a highlander with the ~10 degrees drop at night?
My friend has a N. dubia with an automatic cooling/heating/misting setup but I don't want to take a cutting and kill it

In my experience with highlanders , having a significant temp drop at night promotes the plants growth and development. Cooling the roots significantly at night is key for my highlander species to grow healthy . During the summer sone times it's hard for me to consistently get a proper 10 degree temp drop and my highlanders definitely digress a bit... Nepenthes can be finicky but are extremely forgiving as well. Maybe try growing an easier highland/intermediate species for a bit to get the hang of it. N.Dubia grows pretty high up so definitely on the cool side of things. I'm sure it can handle a little warmer than true highland conditions but it's nice to have a target to stay as close as possible to. Keep the humidity high as well. When my humidity is low , my glabrata and jam an pitchers don't last too long. This is just my experience , hope other people can help you out as well. Best of luck!

This will probably take place over a period of time. Generally, your first sign of heat stress will include the growth tip blackening and dying. After that, it's only a matter of time before the rest of the plant goes.

Does this go for seedlings as well?

Yes. Seedlings may last for a while - a few months - but eventually they'll start dying off if you can't cool them down enough.
