Nepenthes Stem Cuttings Failing: Heat and Dry Media

Cuttings under artificial light 1 week, all dying. 60W wide-spectrum bulbs 10 inches away, 24 hrs, humidity dome, safer garden fungicide spray. Burned from lights?

Diagnosis: Too Dry, Possibly Hot

Jeff Dallas: cuttings look hot. Fluorescent or incandescent? Big difference. Media moisture? Perlite not damp enough. Check dome temp with thermometer—80s°F ideal. Move light back if hotter.

Follow-Up: Fluorescent, Media Dry, Temp 78°F

Grower: fluorescent, media dry (added water but not enough). Temp 78°F. Too late? Lighting adequate?

Jeff: 10" not close for fluorescents, but 78°F is fine (almost cool). Media too dry—leave ¼" water in chamber bottom. Some cuttings look fine; may lose some, others strike. Never 100% success.

Good Growing!
