GERMINATION METHOD (direct sow vs start indoors, etc.) Sow immediately—viability drops quickly. Surface sow on long‑fiber sphagnum or a clean carnivorous plant medium in high humidity with airflow. PRE-TREATMENT (scarification / stratification / soaking, only if required) None required. Focus on freshness and cleanliness. Rehydrating sphagnum with very hot water before sowing can reduce contaminants. SOWING DEPTH Surface sow only—do not cover. LIGHT REQUIREMENT (light/dark to germinate) Bright, diffuse light; avoid intense direct sun that overheats the enclosure. TEMP RANGE Warm, steady conditions; many growers target ~26–32°C (80–90°F) days and avoid cold nights. MOISTURE & MEDIUM Keep the surface very damp but not waterlogged. Use low‑mineral water; maintain humidity with air exchange to deter fungus. DAYS TO GERMINATE Very variable—often 4–8+ weeks, but can range from about a month to many months. NOTES (dormancy quirks, transplant tips, etc.) Mold is the main enemy—use clean media, fresh air exchange, and avoid over-saturation. Let seedlings size up before any transplanting.
Some of plants may have very have specific germination requirements that may not be covered in these general instructions.
Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here. Germination times and germination temperatures are to be a guide only. Many factors can DRASTICALLY affect this.
It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
