Germinating Nepenthes Seeds: Why to Skip the Humidity Dome and Use Open Trays

Dome Dangers

Covered seed trays create stagnant, overly humid conditions that promote mold and damping-off, killing Nepenthes seeds and seedlings.

Sow seeds on moist 50/50 peat/perlite in an open tray.
Place in bright, indirect light (no direct sun).
Maintain 70-80°F (21-27°C) day/night.
Mist daily to keep surface moist; avoid waterlogging.
Germination occurs in weeks to months; no cold stratification needed for most lowland/intermediate species.

Seeds don't need light to germinate; they need warmth and moisture. Light is required only after seedlings emerge.
