Winter Lighting for Highland Nepenthes in Wisconsin: Shop Lights Over SAD Lamps

A Wisconsin grower with highland Nepenthes asks: (1) Can melted snow replace distilled water? (2) Will a 27W SAD (Seasonal Affective Disorder) lamp work? (3) Lighting suggestions for limited space/natural light.

Jeff Dallas: SAD lamps have good spectrum but poor form factor for plants. Best simple solution: two-tube T12/T8 shop light fixture with cool-white tubes (~$20). Suspend on chains, timer, 13-hour day. Nepenthes: 6 inches below. Sundews: 3 inches (double for T5). LED grow lights are more efficient but infinitely complex—white light sources are predictable and easier for beginners. Even experts are still optimizing LED use.

Melted snow: theoretically pure but may collect atmospheric pollutants; distilled/RO water is safer and consistent.
