Why Choose Grow Pros Solutions Air Circulation Under Canopy Light?

Grow Pros Solutions Air Circulation Under Canopy Light is built as a combined under canopy light bar and air tube for high-density flowering rooms, using a spectrum developed by Grow Pros Solutions. It delivers optimized lighting to lower flowers while the aluminum ventilation tube moves air through the lower tiers, helping under canopy rows keep pace with the top canopy in both development and finish.

By bringing light and air into the lower plant tiers, it supports stronger flower set, better structure and size, and a more even finish from top to bottom—without adding separate duct runs or extra under canopy hardware that block light or airflow.

 

Dual Function: Yield Support + Microclimate Control

In high-density canopy environments, the under canopy tier is where both light levels and air movement drop off first. This system is built to address both at the same time:

    • Commercial-proven spectrum: Full-spectrum output with roughly 60% red content supports higher yields and helps lower flowers finish denser and larger.
    • Airflow through the canopy: The aluminum ventilation tube lets air from external fans move along the row and through the canopy across the whole grow layer, and can be paired with the Quetzalcoatl Air Circulation System from Grow Pros Solutions or other compatible inline/duct fans (fans sold separately) to keep airflow more even around the crop from top to lower flowers.

 

Aluminum Ventilation Tube, Built to Scale

Each unit uses a built-in aluminum ventilation tube, making the fixture part of the under canopy air system, not just a light bar. Each fixture connects to the next using a rubber duct connector to create a continuous airflow path along the row.

  • Built-in aluminum ventilation tube for durability in demanding grow-room conditions
  • Rubber duct connector compatibility for easy multi-unit extension along rows
  • Compatible with multiple Grow Pros Solutions fan options to match different room layouts and airflow paths

Q & A
What are the recommendations for bench width and plant count for optimal results?

For achieving superior growth results, it's essential to consider the width of your facility's benches and the number of plants you arrange on them. Here’s a concise guide:

  • Bench Width: If your bench measures 4 feet or narrower, it's advisable not to exceed three plants in width. This setup maximizes space without overcrowding.

  • Plant Count: Running your facility with a slightly reduced plant count, specifically three plants across instead of four, can enhance plant health and yield.

Lower planting densities facilitate improved airflow around each plant. This increased circulation significantly boosts the productivity of your lower canopy. By managing spacing effectively, you encourage a healthier growing environment that promotes robust plant development.

Adopting these recommendations can lead to improved air circulation and better overall plant performance, helping you achieve optimal horticultural results.

What is the method for calculating the required number of power cords and extensions for a lighting setup?

When planning your lighting setup, it's essential to determine how many power cords and extension cords you'll need. Here's a step-by-step method to get it right:

  1. Identify Your Power Requirements
    Each bench or section of your setup will require at least one power cord. However, this can vary based on the number of lights and their total power draw.

  2. Understand Daisy-Chaining
    Daisy-chaining allows you to connect multiple lights in series, reducing the number of power cords needed. However, there is a limit to how many lights can be safely daisy-chained:

    • For lights operating at 1.0 Amps on a 120v circuit, you can chain up to 10.
    • For lights running at 0.5 Amps on a 240v circuit, the limit increases to 17.
    • With lights at 0.43 Amps on a 277v circuit, you can chain up to 20.
  3. Apply Scenarios for Better Understanding

    • For Example: If your setting involves 240v lights where each row holds 6 lights and you have 2 rows (totaling 12 lights), then a single power cord and an extension per bench would suffice.
    • Another Scenario: If each of your rows has 12 lights and you have 2 rows (24 lights total), you’ll need two power cords for each bench.
    • Yet Another Example: With 3 rows and 8 lights per row (totaling 24), the requirement would be two power cords plus an extension cord for each bench.

By following this method, you can ensure your lighting setup is both efficient and safe. Accurate power management not only helps in reducing costs but also prevents potential electrical hazards.

What is the importance of waterproof connectors in under canopy lighting systems?
