Cooling Strategies for Highland Nepenthes hamata

Weylin grows N. hamata at 84°F day / 75°F night with 40–60% humidity under 60W lights (14-hour photoperiod). He's concerned about insufficient night cooling for this highland species.

Jeff Dallas noted the plant actually looks healthy. The key is night cooling. Suggestions:

• Move to a terracotta clay pot—evaporative cooling from porous walls lowers root temperature. Water attentively (dries faster).
• Add a small fan at night for gentle airflow to enhance cooling.
• If needed, cool the room with a window AC unit or thermoelectric chiller (costly).

In a follow-up, Weylin asked about LED vs. CFL heat output. Jeff confirmed LEDs run cooler. Even better: a 48" T8/T12 shoplight with cool-white (5000K) or daylight (6500K) tubes provides more light, less heat, and lower cost than LEDs.

Good Growing!
