Thanks Rob! I was actually getting a bit concerned that the leaves were not reddening as the earlier leaves but the pitchers have increased pretty dramatically despite the lack of pigment. There simply may be less UV coming through the power compact florescents it's growing under as the bulbs are quite old (might be a year old, might be two). I will probably put a 400W metal halide ontop the chamber instead of replacing the 200 watts worth of PCs (replacing the bulbs would cost the same as running the unused halide for six months).
More light has always got to be better right? Is it possible I could damage a Nepenthes with too much light even if humidity is high (90%), temps are correct and the air is moving?
