Highland Nepenthes Terrarium Design: Temperature Swing Solutions

A grower converting lowland terrarium to highland asks about drilling side holes for night cooling vs partial top opening.

Simpler Solution

• Lights on = day heat; lights off = night cool
• Partial top opening (like lowland setup) sufficient
• Room temps 50-60°F at night = perfect
• Mist before bed for humidity

Upgrade Option

• Ultrasonic fogger (frog terrarium type)
• Run at night — mimics natural fog cycle
• Dramatic visual effect
