Cooling Terrariums for Heat-Sensitive Carnivorous Plants: Fans, Ice, and Peltier Options

A university student moved from cool mountains to a city with 100°F+ summers. Their Cephalotus and Heliamphora terrariums overheat despite computer fans. The expert (Dan) suggests:

Small fan under lights: drops temp 7–10°F.
Large ice packs at night (lights off): drops 20–30°F.
Thermoelectric (Peltier) coolers: viable for small tanks, prices reasonable.
Long-term: plug-in "ice chests" converted to terrariums.

The grower combined fans + frozen bottles, achieving high 60s/low 70s°F in winter; summer may reach 86–95°F. Peltier units are worth exploring for hotter months. The expert commends the grower's extensive collection and experience since age 11.
