Greenhouse Grow Lights

Greenhouse lights are designed to supplement natural sunlight, ensuring plants receive consistent light even during cloudy days or shorter seasons. These LED greenhouse lights help growers hit target Daily Light Integrals (DLI), which are critical for crops like tomatoes, peppers, and lettuce.

Grow Light Central offers efficient greenhouse LED lights tailored to greenhouse layouts, beam angles, and mounting. They are ideal for spaces from grow benches to full greenhouse aisles.

Frequently Asked Questions

Should I use grow lights inside my unheated greenhouse, or are they better for indoor seed starting?

Most growers recommend using greenhouse grow lights indoors where you can control temperature and humidity. In an unheated greenhouse, fluctuating temps and wind make grow lights less effective and potentially unsafe if left unattended.

When is the right time to move seedlings from grow lights indoors to the greenhouse?

Transfer seedlings to the greenhouse during the day once they have several true leaves and outdoor temps stay above 50°F. Bring them back inside at night if your greenhouse isn’t heated. Monitor temperatures closely to avoid cold stress or overheating.

Will my greenhouse be useless if I buy grow lights?

No! A greenhouse and grow lights complement each other. Use grow lights indoors for controlled seed starting, then transition plants to the greenhouse to acclimate to outdoor light and airflow before planting in your garden.
