Nepenthes distillatoria Needs Heat: Lowlander Temperature Requirements

Grower's N. distillatoria (terrarium, distilled water, 1600 lumens, 66–73°F, 89–100% RH) struggling after July repot with Superthrive soak.

Problem

Too cold. N. distillatoria is a lowlander from Sri Lanka—needs days in 80s/90s°F (27–35°C), nights ≥70°F (21°C). Same as N. bicalcarata, N. ampullaria.

Solution

Add horticultural heat mat (e.g., Hydrofarm seedling mat). Avoid regular heating pads—they get too hot. Tin foil won't work.
