Optimizing Grow Light Usage for Greenhouse Seedlings

Introduction

Proper grow light management ensures stocky, healthy seedlings for tomatoes, peppers, strawberries, and greens in a greenhouse setting.

Light Duration for Seedlings

• Small seedlings: 10–12 hours per day.
• After fourth true leaf set: Reduce to 8–10 hours per day.

Proper Light Distance

Keep lights 3 inches above the tallest seedlings at all times. This prevents leggy growth and promotes sturdy stems.

Conclusion

Adjust light duration as seedlings mature and maintain close proximity for compact, vigorous plants ready for transplanting.
