Diagnosing Leaf Browning in New Nepenthes: Acclimation, Lighting, and Species ID

Acclimation Stress

Newly shipped Nepenthes often show edge browning as they adjust to new humidity, light, and water. Give 2–3 weeks before judging. The fuzzy brown tip on new leaves is normal emerging trichomes.

Lighting Check

An 18W CFL at 14 inches is modest. Ensure the plant gets 12–14 hours of bright light. Using two different lights (CFL day, red/blue LED night) is unnecessary; a single full-spectrum source on a timer works better.

Species Note

Your plant is N. ‘Poi Dog’ #65, a hybrid that appreciates stable conditions.
