Consequently, larger pitchers may grow from such points without putting undue strain on the plant itself. I've observed this phenomenon many times, with plants growing in many different media. A particular example which comes to mind is that of an N. rafflesiana which was producing an upper pitcher for me about six years ago. As the tendril lengthened, I placed a wooden dowel in its path, around which it subsequently wound. This dowel was anchored to provide support to the pitcher which developed from the tendril, and it grew into the largest N. rafflesiana upper I've ever had -- 40 cm long! It was fantastic, and the dowel provided no extra humidity at all!
The moral of the story: if you want larger pitchers, provide optimal conditions for the entire plant, and support the tendrils as they develop with whatever you have at hand.[/QUOTE]<span id='postcolor'>
I have to disagree in a way. personally, my nepenthes ventricosa started to get bigger pitchers in the fall, when humidity was raised. one pitcher was on the soil, and it grew to about 4-5 inches. it then grew another pitcher that hung, which grew to almost 5 inches.
this might not make sence, but i have to disagree with you with plants with small pitchers, at the plant can easily support it, but i agree with you with plants with large pitchers. the plant with large pitchers can't support the pitchers easily (like your 15 inch rafflesiana pitcher), so when it has support, you get larger pitchers.
(this may go against what i have just said, but maybe lower pitchers are generally larger because they have support!? )
ok, does this make any sence to you guys? if not, remember i stayed up till midnight, and didn't get to sleep untill 2...
