THROUGH THE Cultivator's LENS Hands-On Evaluation

Who This Is For

  • You are upgrading to the E900 because your 5x5 canopy needs more intensity than standard 600W or 700W bars provide.
  • You are moving to 5 foot wide tables because your current light footprints leave the edges of your crop underlit.

What We Found

  • The 59.5 inch width is massive, so make sure you have a second set of hands when mounting this 55 pound beast.
  • We noticed the passive cooling keeps the room temperature stable even when running this at full 1000 watt output.

What Users Say

  • Operators who swapped to this XL frame say they finally stopped seeing light drop-off on their 5 foot wide benches.
  • Commercial facilities running these say the IP65 rating holds up perfectly against high humidity and daily cleaning.

Grower's Choice ROI-E900 Commercial LED Grow Light

Struggling to achieve consistent, high-quality yields across your large-scale grow? The Grower's Choice ROI-E900 is the heavyweight champion you've been waiting for. This XL 8-bar powerhouse, nicknamed the “Fat Boy,” is engineered to deliver an overwhelming 1000 watts of supercharged photon output, blanketing your canopy with the intensity needed for maximum production.

Using Grower's Choice's proven GC-3K Full Phase PAR spectrum, the ROI-E900 radiates a perfectly balanced light across a generous 4’x5’ to 5'x5' footprint. It's designed specifically for commercial cultivators with wider tables or trays, ensuring deep canopy penetration and uniform growth. If you're looking for a slightly smaller but equally powerful option, consider the popular Grower's Choice ROI-E720. For maximum power and flower, the ROI-E900 is the definitive choice among professional LED grow lights.

FAQs

What is the ideal coverage area for the ROI-E900?+

The ROI-E900 is designed for large-scale coverage. It excels in a 4' x 5' area for flowering plants requiring very high intensity, and can effectively cover a 5' x 5' area for vegetative growth or flowering plants that need slightly less intensity.

Is this light suitable for both vegetative and flowering stages?+

Yes, absolutely. The ROI-E900 uses the GC-3K Full Phase spectrum, which is a full-spectrum light designed to provide the ideal wavelengths for all stages of plant growth, from seedling and vegetative phases right through to heavy flowering.

How does the ROI-E900 compare to the ROI-E720?+

The ROI-E900 is the more powerful fixture, drawing up to 1000W and designed for wider coverage areas (4'x5' to 5'x5'). The Grower's Choice ROI-E720 is a 720W fixture ideal for standard 4'x4' or 5'x5' spaces. Both offer the same high-quality spectrum and build, so the choice depends on your coverage needs and desired light intensity.

What kind of controller do I need to dim the light?+

The ROI-E900 is compatible with any 0-10V controller. For the most advanced control, including sunrise/sunset simulation and precise scheduling, we recommend pairing it with the Grower's Choice Master Controller.

What is the recommended mounting height above the canopy?+

For optimal performance and to prevent light burn, the fixture should be mounted at least 6 inches above the plant canopy. You can adjust the height as your plants grow to maintain this distance.

How can I learn more about choosing the right grow light?+

Choosing the right lighting is crucial for your success. For a detailed breakdown of what to look for in a quality fixture, we recommend reading our expert guide on what to pay attention to when buying LED grow lights.
