Carolina Reaper Seeds (Capsicum chinense)

Carolina Reaper is an extremely hot tropical chilli variety known for its intense heat and characteristically slow germination. Its thick seed coat means patience, warmth and consistent moisture are especially important during the early stages of growth.

Sow Carolina Reaper seeds approximately 5 mm deep in a premium seed-raising mix. Germination typically takes between 14 and 35+ days, depending heavily on soil temperature and growing conditions.

🌱 Germination Tip
For best results, maintain a consistent soil temperature of 26°C–30°C, ideally around 28°C, using a heat mat and humidity dome. Pre-soaking seeds in lukewarm water for 12–24 hours before sowing may help speed up germination.

🌱 Sowing & Germination Guide
Step Recommendation Growing Notes Pre-Soaking 12–24 hours Soak seeds in lukewarm water before sowing to help soften the thick seed coat and potentially improve germination speed. Sowing Approx. 5 mm deep Sow into a premium-quality seed-raising mix. Soil Temperature 26°C–30°C Aim for a steady temperature of around 28°C for best results. A heat mat is highly recommended. Humidity Warm and humid A humidity dome can help maintain stable warmth and moisture while seeds germinate. Germination 14–35+ days Carolina Reaper seeds can germinate slowly. Cooler or inconsistent temperatures may extend the germination period.
📏 Spacing & Growing Conditions
Requirement Recommendation Plant Spacing 50–100 cm apart Row Spacing 80–120 cm apart Sun Full sun position Soil Fertile, well-drained soil Watering Allow the top layer of soil to dry slightly between waterings. Harvest Approx. 16–24 weeks from sowing, depending on location and weather conditions.
💧 Feeding Guide
During germination: Do not fertilise while seeds are germinating.

After true leaves appear: Begin feeding once the seedlings develop their first true leaves.

Recommended strength: Apply a liquid fertiliser at approximately ¼ strength once per week.
⚠ Carolina Reaper Safety
Carolina Reaper is an extremely hot chilli, reaching heat levels of up to approximately 2.2 million Scoville Heat Units (SHU).

Always wear gloves when handling the seeds, leaves or fruit, and take care to avoid transferring chilli residue to your eyes or face.
QPS Grower’s Tip
Heat is the key to Carolina Reaper germination. Keep the seed-raising mix consistently warm at around 28°C and be patient — healthy seeds can still take more than a month to emerge.
