Get to Know the GrowPros Under Canopy Light 8ft Model 3 - UVA + Blue + 5000K / Deep Red + IR + 3000K

The Grow Pros Solutions 8ft Under Canopy Light Model 3 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.

Growpros Solutions’ first-ever under-canopy grow light dual channels are engineered to enhance the yield and color of lower flowers. These supplemental lights can significantly enlarge B-buds and C-buds, promoting better growth and development in areas that typically underperform.

The GrowPros Solutions 300W 8′ Under Canopy Grow Lights Model 3 Dual Channel have been meticulously designed by hydro growers for hydro growers. This innovative lighting system features two channels: one 150 Watt with a Blue + White + UVA spectrum and the other with a 150 Watt Red + IR + White spectrum. Both channels are dimmable, allowing for precise control over light intensity to meet the specific needs of your plants at different growth stages.

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.

1 Power Cord is included for free in every pack of 2.

Who Should Use This Light?

  • Serious Indoor Growers: Ideal for those running high-density cannabis grows where maximizing every bud site is critical.
  • Commercial Cultivators: Perfect for large-scale operations looking to increase the yield and quality of lower canopy buds.
  • Hydroponic Growers: Designed by hydro growers, this light thrives in DWC, aeroponic, and NFT systems where light penetration is limited.
  • Advanced Hobbyists: Experienced home growers aiming for professional-grade results with full canopy optimization.

Best Applications

  • Vertical & Multi-Tier Grows: Essential for stacked cultivation where lower plants often lack sufficient light.
  • Dense Canopy Setups: Works best with bushy strains or SCROG (Screen of Green) training methods.
  • Flowering Phase Boost: Red + IR spectrum enhances bud density and trichome production during late bloom.
  • Supplemental Lighting for HPS or LEDs: Fills in gaps beneath the main canopy, ensuring lower buds develop properly.

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 like cannabis. 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 cannabis strains?

Absolutely! We offer customizable spectrums and intensities to match the specific needs of different cannabis strains. Whether you're growing high-THC or CBD-dominant plants, our tailored lighting solutions help optimize growth, potency, and terpene profiles.
