Under-Canopy Grow Lights

Under-Canopy Grow Lights are the secret weapon for boosting plant growth where overhead lighting can’t reach. By delivering supplemental side lighting to shaded lower branches, under-canopy lights increase light penetration, improve airflow exposure, and help drive bigger, more consistent yields across the entire plant.

Why Use Under-Canopy Lighting?

• Even Light Coverage: Targets the lower canopy that main grow lights often miss.
• Higher Yields: Energises shaded branches for denser flowers and more uniform harvests.
• Healthier Plants: Reduces stress from uneven light distribution and encourages balanced growth.
• Flexible Setup: Designed to fit alongside LED grow lights or HPS fixtures as a supplement.

When to Use Under-Canopy Lights

Under-canopy lighting is most effective during the late vegetative and flowering stages, when plants have developed dense canopies that block light from reaching the lower growth. By supplementing with side lighting, you ensure that every part of the plant receives usable light, improving structure and overall performance.

Under-Canopy Lighting FAQs

Do I need under-canopy lights if I use LEDs?
Yes—while LEDs provide strong top lighting, under-canopy lights still improve penetration and help shaded lower sites thrive.

What stage should I add under-canopy lighting?
Start in late veg to promote stronger branching, and continue through flowering to maximise lower yield sites.

Are under-canopy lights worth it?
If you grow bushy plants with dense foliage, under-canopy lights help prevent wasted lower growth and increase total yield.

Can I use CFLs or strips as under-canopy lighting?
Yes—many growers use compact CFLs or LED light strips under the canopy as a cost-effective supplemental solution.
