This seasons pitchers are getting quite huge. This one hasn't even started to open yet - N. truncata X spectabilis:
Got big pitchers coming? Post pics!

Is it just me or does that picture look wrong? LOL
That's going to be a nice pitcher!

Nice picture, but why is there a fern in the background? Are you trying to replicate a jungle-like environment?
You get ferns as weeds? I usually just end up with grass or similar such plants, which I proceed to remove whenever I see them. Carefully, so their roots don't break off and spread the weeds.
Speaking of giants, this is the season's first new pitcher on my N. naga. I know, I know, not exactly a giant, but its much bigger than the previous one.
Neps have a great deal of seasonality for me, though I have a completely artificial environment. Typically offshooting/vegetative growth (spring)--> pitchering (summer) -->flowering (fall/winter) -->sluggishness (winter)
Varies by species, too. I let them do what they want without too much prodding. I feed when they seem to want to grow, and I withhold when they don't.
You'd think with completely artificial lighting and temperature control they wouldn't have any seasonal patterns.
