summer has passed and light levels are decreasing by every day here in northern hemisphere. My N. ephippiata got full sun for about 7 hours every day during summer. Although nearly all leafes which can be seen on the picture were grown under these conditions, they were severely burned.
Although pitchers look OK:
So in contrast to some believe not all nepenthes are able to adjust to very bright light levels. I.e. N. lavicola, N. macrophylla, N. singalana and some others grow very well under the same light levels.
P.S.: I hope Rob won't kill me, when seeing what I'm doing with his plants...
