Choosing the Right Color Temperature for Nepenthes Under T5 HO Fluorescent Lights

3000K Is Too Warm

3000K mimics High Pressure Sodium—plants grow but rarely pitcher. Nepenthes need 5000–6500K for proper pitcher development.

Recommendation

Use 6500K T5 HO tubes (standard grow-light spectrum). Most Nepenthes (highland or lowland) are high-light plants; color temperature matters more than altitude category.

Carnivorous Plants: Identifying Nepenthes: 'Miranda' and deRoose's 'Alata'; Repotting a New Nepenthes: Acclimate First or Pot Immediately?; Optimal Lighting for Nepenthes: Bulb Selection and Placement; Lighting Setup for Nepenthes 'Miranda' with Supplemental Sunlight; Nepenthes cutisii Flower Stalk: Remove Unless Breeding; Is This Nepenthes glabrata? Yellowing and Identification Doubts; White Mold on Nepenthes Soil: Repot or Treat?; Identifying Nepenthes rafflesiana and Understanding "50% Shading"; Choosing the Right Soil for Nepenthes: Coconut Fiber vs. Sphagnum Moss; LED vs. CFL for Nepenthes Lighting: Lumen Output Matters
