Discolored Nepenthes in a Terrarium: Light, Water, and Tank Maintenance

A New York grower's terrarium Nepenthes (1 ft from 48W grow light, unknown soil, nursery-built "self-watering" tank) showed leaf discoloration after winter. Tank mates: Drosera, Pinguicula, weed. VFTs in fridge for dormancy.

Key Issues

Watering: "Self-watering" is a myth. Tanks lose moisture; top up monthly. Watch for mold.
Light distance: 1 ft may cause darkening (normal for many species in bright light).
Seasonal change: Winter light/angle shift near windows can affect plants.
VFT dormancy: Check fridge-stored VFTs for mold; spray with sulfur fungicide. They thrive as outdoor container plants in spring/summer (zone 8 perennials).
