I grow about 3 feet away from a bright windowsill and humidity is about 50% day and night.........
this plant has done great things for me in the past(like eight inch picthers), but recently has made 2 new growth off the base an extended its climbing stem 3 feet, and not made a single picther.....the average leaf size on the main plant is about 1.5 feet.....
my guess is its just been a really BAD winter lightwise(we have had lots of clouds) and the plant has its energy going in other directions at the moment....
what do you think? [img]http://www.**********.com/iB_html312/non-cgi/emoticons/rock.gif[/img]
Both reasons could be the answer
If you had pitchers in the past at only 50 % humidity, then this particular plant is patient with low relative humidity. I'd say it needs more light. For such a cloudy winter, you could add a grow light to supplement.
