I've had both of these for 9 months or so. They are both growing vigorously - but not pitchering. They both have started to inflate pitchers, only to abort them early on. They are in my highland growshelf, under the following conditions:
Daytime humidity drops to about 65% - it's the best I'm able to attain in the day.
Nightime humidity is 85%+
Daytime temps usually 78F-80F, occasionally reach 83F.
Nighttime temps 58-59F.
16 hours under 4 40 watt 3000 lumen bulbs.
Just about all my other highlanders are flourishing - but these two won't pitcher for me. I figured for a long time they were just settling in - but the other plants I got in the same order are fine, and I figured by now these two would be fine. Any ideas?
