Dustin, the aristo is in fairly typical highland conditions. Thermastat is set to 60 at night, so it might get down to 57 or 58, but I doubt any lower. It's really close to the lights. I have noticed that aristo loves light. It's in a tank which is, oh, 85% covered (give or take), so the humidity is rather up there....though I never ran into a humidity tempermentalness over the summer while it was growing on the deck railing. I would say that the most likely culprit for your problem is low light (or, heaven forbid, pests).
Tropics, LMAO!
VFT Guys, I grow the eymae as a highlander (though I've heard rumors it's not tempermental with temperature...those are unconfirmed). This is the first real pitcher on the plant for me, but then I've only had it since just after the X-mas (not bad for about three weeks, eh?). It is close to the lights and under high humidity (don't have numbers for that, though, sorry).
The trunxvent I would immagine could take just about anything. It grew great on my deck railing last spring/summer/fall. I currently is growing fine in my grow room which I would call intermediate/lowland. Doesn't seem to care one lick about temps. Also, it has produced pitchers for me in all but the lowest humidity (these last two were produced within a variable range of 30% to 55% depending on how often I remembered to fill the humidifier). So, in short, you could grow them together if you gave more thought to the eymae.
Thanks everyone for the kind words!
What a source of encouragement everyone is!
