Terrarium Setup for Ultra-Highland Nepenthes: Equipment, Cooling, and Long-Term Strategy

A grower wants a terrarium for N. rajah, villosa, aristolochioides for several years. Expert warns: cost and complexity are high – not just a tank and light. Recommends:

• 50+ gallon aquarium (used/free via Craigslist), partial glass cover.
• LED lights (vegetative spectrum) or T5 fluorescents (4 tubes); timer.
• Thermometer essential; hygrometer helpful.
• Small computer fan for ventilation; ultrasonic humidifier or Exo Terra fogger.
• Greenhouse-tank style: plants in individual pots with water trays (flexible). Or planted with sloped media.
• Distilled/ZeroWater only; 13-hour photoperiod.
• Days 70s–80s°F, nights 55–60°F – night cooling is hardest. Window AC or retrofitted thermoelectric cooler from portable fridge.
• Monitor fungus; treat promptly.

Suggests consulting orchid forums for high-elevation cooling ideas. Research thoroughly before investing.
