Night Temperature Drops for Cephalotus and Heliamphora

Cory asked about night temperature drops for Cephalotus and Heliamphora grown indoors at 74°F (AC 24/7). He uses ice packs in a fish bowl for Heliamphora but wasn't sure about duration or necessity.

Jeff Dallas replied: at 74°F average, no extra cooling is needed. Heliamphora naturally sees 70s day/50s night, but air-conditioned homes are already cool. Cephalotus comes from maritime SW Australia with similar temps. Keeping roots cool is beneficial—terracotta pots provide evaporative cooling.

Follow-up: Cory discovered his plant room hits 92–95°F due to skylight/window sun. He moves Heliamphora to a cooler with ice packs nightly (holds 57°F). Jeff warned against daily moving—plants constantly re-adapt. Better solutions: terracotta pot + small fan, or a fluorescent-lit aquarium (40-gal tank, 2-tube shoplight) for stable, cool conditions. Natural sun in a fish bowl risks overheating.

Good Growing!
