Starting Hot Peppers from Seed: The Heat Secret

Hot peppers are notorious for slow, spotty germination. The secret? Consistent, warm heat.

Key Requirements

• Temperature: 80–85°F (27–29°C) constantly. Use a heat mat.
• Time: 14–20+ days to germinate (vs. 5–7 for tomatoes).
• Moisture: Uniformly moist, never soggy.
• Light: Not needed for germination, but critical immediately after.

Step-by-Step

1. Sow seeds 1/4 inch deep in sterile seed-starting mix.
2. Cover tray with humidity dome; place on heat mat.
3. At first sprout, remove dome and move under 40W fluorescent lights (2–3 inches above plants).
4. At first true leaves, transplant to individual cells.
5. Fertilize with fish emulsion or 12-12-12 every 10 days.
6. Keep lights 8 inches above plants; 14–16 hrs/day.

Hardening Off and Transplanting

After last frost, shade for 10 days, then plant in full sun (8+ hrs). Peppers love heat but drop blossoms above 90°F (32°C). Provide consistent moisture and stake if needed.

With warmth and patience, you’ll grow vigorous pepper plants loaded with fruit.
