Nepenthes Not Pitchering in Bathroom: Light, Humidity Stability, Species ID

California grower's hanging Nepenthes in bathroom (stained glass ceiling, shower humidity, air movement) has blackening old pitchers, new ones abort. No saucer, kept moist.

Factors

• Light: Needs very bright, near full sun. Bathroom light likely insufficient.
• Humidity swings: Showers cause drastic RH changes—pitchers dry before forming.
• No saucer needed (prefers moist, not wet).
• Misting not required—stable environment key.
• Species ID matters—some far more demanding.

Fix

Move to well-lit, stable spot; allow time to adjust.
