When gardeners comprehend seed germination, they open the door to successful gardening practices. Germinating seeds involves controlling temperature, managing moisture, and ensuring the quality and intensity of light. One item required is a drainage container, and the warmth will depend on the species. For early control, humidity domes are used, while seedlings develop stronger with bright light. Combined, these conditions are designed to eliminate typical failed germination.
Temperature Regulation
- Warmth-loving plants like peppers need 80-85°F (27-29°C)
- Cool-season crops like lettuce prefer 65-70°F (18-21°C)
- Heat mats maintain precise ranges for different species
Moisture Management
- Soil should feel like a damp wrung-out sponge
- Mist surfaces instead of pouring to prevent displacement
- Remove humidity domes immediately after sprouting
Light Requirements
- Position lights 2-4 inches (5-10 cm) above seedlings
- Provide 12-16 hours daily using full-spectrum LEDs
- Rotate trays for even exposure preventing leggy growth
