🔥 Step 1: Germination — The Key to Success

Pepper seeds thrive in warmth. For fast, even sprouting, keep the soil between 80–85°F for hot types and 78–82°F for sweet or ornamental peppers.

Use a heat mat and humidity dome for best results. Lightly mist the soil daily to prevent drying out — consistent moisture is vital. Expect germination within 7–21 days, depending on variety.

🫑 Step 2: Seedling Care & Transplanting

Once seedlings emerge, move trays under bright LED grow lights or into a sunny greenhouse.
Water moderately and begin feeding with a light, balanced fertilizer once true leaves appear.

Before transplanting outdoors, harden off seedlings for about a week — gradually exposing them to wind and direct sunlight.
Transplant when soil temps exceed 70°F and nights stay above 55°F.
