Nepenthes rafflesiana: Temperature Trumps Humidity

Lowland N. rafflesiana—worried about humidity? Temperature matters more.

Ideal Temps

• Nights: >70°F (60°F minimum, slows growth).
• Days: >80°F.

Humidity

Acclimates to lower humidity if soil stays moist, light is bright, temps are ideal. Expect some leaf spotting/smaller pitchers—but it adapts.

Skip the Terrarium

This gets huge. No terrarium fits long-term. Grow as a houseplant—easier to acclimate small plants.
