Winter Grow Light Setup for Tropical Pitcher Plants: T5/T8 Guidelines

A grower (Novi) plans winter grow lights for tropical pitcher plants due to poor windows. Asks if T5/T8 bulbs suffice and daily hours needed.

Jeff Dallas: Fluorescent light shelf is excellent for winter/poor windows. T5 or T8 both work. Use "Daylight" / 6500K spectrum. T5: plants ~18 inches below. T8: plants ~3–4 inches from tubes. 13-hour day cycle. Combining window + lights is even better.

Highland Nepenthes may prefer slightly cooler nights; light shelf in a cool room mimics this. Consistency in photoperiod drives healthy growth and pitcher formation.
