personally weird and obscure...

Vincent,
I think if you said none of us in the tropics (Indonesia, Malaysia, Singapore & Thailand) never tried growing H/L plants, then you're wrong... The results were usually poor, with neps growing smallish pitchers (best case scenario without plant dying). Intermediate neps however are more forgiving to be grown in L/L tropical weather with good results. With all this being said, there will be always some exception....

From my little experience of growing nepenthes, I have found only a handful of intermediate to H/L nep species that can do some what ok in L/L tropical weather. However, hybrids of intermediates or H/L nep with L/L species will be very adaptable to L/L tropical weather.

Most temperate countries have weather pattern similar to intermediate condition hence IMHO have more flexibility in terms of growing nep species or hybrids from wider temperature range with better results.

FYI, most of the nep growers in L/L tropical weather region kept the plants outdoor hence most of the plant will experience what mother nature will provide directly without any sort of shelter (at most some shade) be it sun or non stop tropical monsoon downpour...

I get what you're trying to convey and encourage and your intention is good, it's always good to have someone remind and push us for we can move forward... thanks.
