Indoor Mini-Greenhouse Setup for Nepenthes in Northeast Winters

Transitioning a Mini-Greenhouse Indoors for Winter

A Long Island, NY grower (Zone 7a) has a mini-greenhouse with stable summer temps (80–90°F day, 60–70°F night) and humidity (50–70% day, 70–90% night). They plan to move it indoors for winter (night temps 30–40°F) and ask for setup advice.

Expert Setup Plan

Jeff Dallas: Place greenhouse in a north-facing window (bright ambient, no direct sun). Supplement with two compact fluorescent fixtures (150W equivalent, 4" from plastic) on a 12–14 hr timer. Keep greenhouse partially open for ventilation. Elevated humidity speeds growth but isn't strictly necessary.
