N. aristo and other highlanders from seed?
I recieved a couple of N. aristo and other highlands seeds like 4 months ago and now they are starting to germinate. So long some few aristo, dubia and jacquelineae have sprouted but i'm quite excited.
I'm from Argentina. Winters are almost perfect for highlanders (lol) but the middle of the summer can be unforgiving (30º almost every day and 35º sometimes, 20-25º every night)
Right now the seed tray is in the balcony under a table so the sun never hits it directly. It has been there since I planted the seeds and they germinated under winder end - spring conditions. The summer is starting in 20 days. During this days the day gets to 25º - 30º and the night drops to 15-18º.
I was planning to, when the summer starts to hit hard, enter all the seed trays, put them in a fish tank under fluorecent tubes and cool them with frozen bottles during the nights.
The thing is:
When the plants get big, I won't be able to do that (imagine a N. dubia in a small fish tank). Although I plan to build a Highland greenhouse with maybe an AC or a Swamp cooler for the summer nights, I was thinking maybe if I let them suffer the summer from the very beginning of their lives they will acclimate to my region conditions and won't suffer when they are adult.
Of course, since they are rare plants and also live beings (here in my country at least) I don't want to kill them all just because an experiment.
Would you share your thoughts?
Thank you a lot!
No, they won't adapt to warm nights. Growing highlanders from seed takes commitment. It'll probably be 4 or 5 years to get to 3". If you could get a terrarium or greenhouse with an AC and humidifier set up before your summer, that would probably be for the best. 15° is probably a bit warm for those species, but they should be ok for a while. Those day temperatures might be a bit high, though.
15c nights is perfectly fine for these species. Also they can be much faster than people think, I would say 3" in four to five years is a conservative estimate. For example, I grew this Nepenthes dubia from seed in three years, it is currently now a two foot vine making full uppers. Here is a pic of the plant from earlier this year:
Also, giving them really crappy conditions when young will just kill them, not acclimate them to those conditions.

First of all: Thank you for the answers!
Don't take me wrong, when I bought the highland seeds I knew it would take commitment and I will do anything they need to grow. I'm just asking because having highland neps in my garden or balcony instead of being inside a greenhouse would be spectacular, and since the seeds are growing so good right now, I thought it would be a good chance to acclimate them. But if you say i'm probably going to kill them if I leave them there during the summer, then I'll bring them inside.
One more question:
If I bring my plants inside for the summer, won't the plants suffer the transition and make it harder to put them back outside during winter?
