Winter Grow Lights for Drosophyllum and Roridula

Supplementing light for Drosophyllum (dewy pine) and Roridula indoors in winter. CF, LED, or HID? Wattage?

Recommendation: T5 fluorescent (2-tube, 4-ft) for most hobbyists—best cost/performance. 6500K, 13-hour photoperiod.

LED: promising but spectral outputs vary; not enough CP-specific data yet to recommend specific units.

HID (400W Metal Halide): excellent for larger collections/greenhouses. We use three 400W MH in winter with great results.

CFL: 6500K, 23W+ works for a few plants. One Drosophyllum thrives under a single 6500K CFL.

Match light to space and plant count. T5 is the sweet spot for most.
