How Under Canopy Lights Can Transform Your Plant Growth and Maximize Yields
Maximizing plant growth and yields is the ultimate goal for any grower. As cultivation practices evolve, one innovative strategy gaining traction is the use of under canopy lights.
These lights, positioned below the plant’s main canopy, provide a much-needed light boost to lower buds that often miss out on essential light.
In this blog, we’ll dive into how under-canopy lights can transform your cultivation techniques and offer practical tips for getting the best results.
Why Use Under Canopy Lighting?
Under canopy lights offer a variety of benefits that can take your cultivation to the next level. Here’s why they are worth considering:
- Improved Light Distribution: Under canopy lighting ensures that lower buds and branches receive enough light, promoting more even growth.
- Enhanced Yield: Plants will produce more buds and flowers in areas that were previously shaded, resulting in higher overall yields.
- Efficient Light Usage: By directing light to where it’s most needed, under-canopy lighting reduces wasted energy and optimizes your lighting system.
When to Use Under Canopy Lights for Maximum Effect
The timing of when to activate under canopy lights is critical to achieving optimal results. Here are some tips for the best practices:
- During the Vegetative Stage: Use under canopy lights to stimulate growth in lower branches while the plant is still establishing its structure.
- In the Flowering Stage: As the plant focuses on bud production, activate the under canopy lights to enhance flowering and ensure lower buds receive adequate light exposure.
💡 Tip: Limit the use of under-canopy lights in early plant growth stages to avoid stressing young plants.
How to Integrate Under Canopy Lights with Other Growing Techniques
Under canopy lights are most effective when paired with other techniques. Here’s how to integrate them into your plant care routine:
- Pruning and Defoliation: Perform selective pruning and remove excess foliage in the lower canopy to allow light to reach deeper into the plant.
- Training Techniques: Use techniques like Low-Stress Training (LST) or ScrOG (Screen of Green) to create an even canopy that maximizes light penetration.
💡 Tip: Use Low Stress Training (LST) to allow for better light penetration and an even canopy.
Managing Light Distribution for Optimal Plant Growth
When implementing under-canopy lights, it’s essential to manage plant growth and ensure the proper distribution of light:
- Adjustable Light Fixtures: Use adjustable lighting systems that allow you to raise or lower lights as the plant grows.
- Monitor Plant Response: Watch how your plants respond to increased light, and adjust as necessary to avoid light stress or burning.
💡 Tip: Always ensure that your lights are positioned to target the lower portions of the plant, but avoid direct exposure to delicate buds to prevent damage.
Essential Tips for Setting Up Under Canopy Lights
Before setting up under canopy lights, keep the following considerations in mind:
- Light Type: For under-canopy applications, use LED or fluorescent lights, as they offer better energy efficiency and are less likely to overheat.
- Heat Management: Ensure that your lighting system does not excessively raise the temperature beneath the canopy. Use fans or ventilation systems to regulate airflow.
- Timing and Duration: Limit the amount of time your plants are exposed to under-canopy lighting. Overexposure can lead to stressed plants.
💡 Actionable Tip: Invest in a timer system to automate light cycles for consistent light exposure without manual adjustments.
Light Management and Environmental Conditions
While under-canopy lights can improve growth, managing the environmental conditions surrounding them is just as important:
- Temperature Control: As under-canopy lights increase heat in your growing space, be sure to adjust ventilation systems to maintain ideal temperatures (ideally between 70 and 85°F).
- Humidity Regulation: Maintain consistent humidity levels to support healthy plant growth. Too much moisture can lead to mold and mildew issues, especially under more intense light.
Plant Health and Light Response
Not all plants respond the same way to under-canopy lighting. Factors such as strain type, growth stage, and overall plant health can influence how well they thrive under additional light.
- Strain Sensitivity: Some strains, especially sativa-dominant varieties, may require gentler light exposure due to their thinner leaves. Start with lower light intensity and gradually increase as the plant matures.
- Growth Stage Variations: Younger plants or seedlings might not benefit as much from under canopy lighting compared to fully mature plants in the flowering stage.

Frequently Asked Questions (FAQs) about Under Canopy Lights
Under canopy lights are specialized lighting fixtures positioned below the plant’s main canopy to provide additional light to lower leaves and buds. They help improve canopy penetration and ensure even light distribution, leading to healthier growth and better yields.
Activate under canopy lights during the vegetative stage to stimulate lower branch growth and in the flowering stage to boost bud development. Avoid excessive use during the early seedling stage to prevent stress.
By providing additional light to shaded areas, under canopy lights promote photosynthesis in lower buds, resulting in more uniform growth and higher overall yields.
Traditional grow lights focus on the upper part of the plant, while under canopy lights target lower leaves and buds. The combination of both maximizes light exposure, improving overall plant health.
Under canopy lights can be installed using adjustable light bars or fixed mounts. Ensure proper placement with a stable power cord and power cable setup for safety. Daisy-chaining multiple fixtures is also an option for larger grow spaces.
Yes! Under canopy light indoor setups are highly effective, especially in dense plant canopies where lower buds receive less light. They are also beneficial in greenhouse environments for improving lower bud development.
