My swamp cooler decided to break down during the hottest part of summer. Luckily I'm able to return it due to the warranty, but I'll have to send it back and then I'll have to find another and set it up. That may be a month or two. So for now, I moved all of my Nepenthes into two terrariums. They get into the low 80s during the day and cooler off into the 70s at night. I don't want to kill my Nepenthes with hot night temperatures. I don't want to have to move 17 plants outside every night where they can take advantage of the 50F nights. What can I do to keep my terrariums cooler at night without losing humidity?
Last night was a bit hot, so it was a bad time to test, but say it gets down to 70F at night and stays around 85F during the day. Will that kill them? What signs will I see that they aren't liking it? Will they just turn black at the last minute or what?
