Here's an observation that may interest some of you:
Recently I got my old grow chamber up and running and my CP's have been much happier with the new living arrangement.
I have a Nepenthes growing in the tank that I believe is N. ventrata. It has been "almost growing" in my chamber for a few weeks following a year of *obscene* neglect -don't ask. I was pretty happy when I noticed that my Nep's were starting to liven up again and pitcher after a bit of a vaction. "Golly gee" I thought, "why not make these puppies even MORE happy by placing an aquarium heater in the tank?"
The temp stood around 72-75degrees F, and I felt it may be a little too cold for my plants. I used an aquarium heater to raise the temp to around 79-80degrees F.
Welll... both of my Nepenthes promptly ceased pitchering within a few days of the temp increase. One of the new leaves of my N. ventrata that was just about to begin unfurling showed a disturbing growth distortion -all bent over and twisted, you know the sight. I did not really think that such a subtle temp increase would cause them to stop pitchering, but even after several weeks there was no sign of new pitcher development.
That really bummed me out, because I have been very anxious to see my N.ventrata to start pitchering once again, and it stopped development with one pitcher 1/5th developed! Bummer
Recently I removed the aquarium heater, and the pitcher development resumed almost instantly.
To make a long story short, an increase of merely ~5 degrees F was all it took to cause my Nep's to cease pitcher development.
That was news to me
