Add deep red spectrum under your canopy to boost bud density, THC production, and total yield with this high-efficiency 250W LED fixture.

The Grow Pros Solutions 8' under canopy light red spectrum version is designed to provide supplemental light to the lower regions of plants in indoor cultivation environments by strategically placing them beneath the top canopy of plants to ensure leaves and flowers below the canopy receive optimal light exposure by eliminating shady areas. Under Canopy Grow Lights, benefits include uniform light distribution, maximized yield, and denser flowers.

Maximize Flowering and THC Concentration

Under canopy lights are designed to illuminate beneath the dense plant canopies where traditional overhead lights struggle to reach. This strategic lighting approach not only boosts the yield but also enhances the quality of your crops by:

Increasing Flowering: By providing essential light to lower canopy areas, these lights promote more extensive flowering even in the shaded parts of the plant.

Enhancing THC Concentration: The added light spectrum encourages the development of THC and terpene compounds, improving the potency and profile of your harvest.

Spectrum Balancing for Optimal Growth

To achieve these benefits, it’s crucial to select the right spectrum based on your existing setup:

  • Model 1 Lights: Ideal for complementing HID top lights, which are rich in ROY (red, orange, yellow) spectrums.
  • Model 2 Lights: Best paired with full-spectrum LED top lights to ensure comprehensive coverage.

This customization allows growers to balance light spectrums effectively, ensuring that every plant receives the optimal wavelengths necessary for peak growth and quality. By integrating these advanced lighting solutions, you can achieve increased yields and superior product quality, setting your harvest apart in appearance and chemical composition.

Interconnect Cables and Power Cords

Additional components can be ordered separately since quantities will depend on the total number of lights and selected configurations.

Note also that the lights connect together without interconnecting cables. The interconnecting cables are only needed to create the U where you have 2 rows of lights on a single bench OR if you need a space (up to 4 feet) between under canopy lights.

See the above chart for limitations on how many lights can be connected on 1 power cable.

  • THC-Focused Cultivators: Ideal for growers aiming to enhance resin production and terpene profiles.
  • High-Density & Vertical Farmers: Essential for stacked and tightly spaced grows where light penetration is limited.

Best Applications

  • Dense Canopy & SCROG Setups: Ensures deep light penetration for uniform bud development.
  • Flowering Stage Boost: Enhances bud density, trichome production, and overall yield.
  • Supplemental Lighting for LED Systems: Balances spectrum gaps and improves lower canopy performance.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.

Does GrowPros offer energy rebates for its products?

Yes! The potential savings from energy rebates are substantial, often covering approximately 50-75% of the overall project cost. To get a personalized estimate of your potential savings, simply contact us and we'll provide a complimentary assessment tailored to your project.

How much energy can I save with GrowPros' energy-efficient lights?

Upgrading to LEDs can cut your energy use by up to 75% compared to old-school incandescent bulbs and around 40% less than HID lights. That means lower electricity bills, especially if you're running multiple fixtures. Plus, LEDs last way longer, so you’ll save even more on replacements and energy costs over time.

Can GrowPros LED lights be customized for different bud strains?

Absolutely! We offer customizable spectrums and intensities to match the specific needs of different strains. Our tailored lighting solutions help optimize growth, potency, and terpene profiles.
