Get to Know the GrowPros 4′ Under Canopy Grow Lights Model 1 Single Channel 125W

Growpros Solutions’ under canopy light 4ft are engineered to enhance the yield and color of lower flowers. These supplemental lights effectively enlarge B-buds and C-buds, promoting better growth and development in areas that typically underperform. By targeting the understory, Growpros Solutions ensures a more uniform and abundant harvest, maximizing every plant's potential.

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.

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

  • Commercial Growers: Ideal for large-scale cannabis cultivation where maximizing lower bud development is key.
  • Hobbyists & Small-Scale Growers: Perfect for those looking to enhance yields without overhauling their entire lighting system.

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.

Why should I choose GrowPros Solutions for my cannabis grow operation?

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.
