1. Choosing the Right Light

Avoid single-bar fixtures for indoor grows—they’re meant for high-bay or greenhouse setups where lights hang far above the canopy. Mounted too close, they cause hotspots and uneven coverage.

Multibar designs provide better uniformity, higher PPF, and can be positioned closer to the plants for better yield.

💡 More even light = better growth and higher returns.

2. Understanding Spectrum Tuning

Spectrum tuning can be useful—as long as you’re still hitting all key photoreceptors (blue, green, red, and far-red). Adjusting red and blue is fine, but avoid extreme shifts that reduce overall intensity or cut out parts of the spectrum.

The idea of “end-of-day far-red” has been debunked by experts like Dr. Bruce Bugbee—daily consistency often performs better.

📊 Focus on canopy light intensity, spectrum coverage, and distribution.

A well-balanced full spectrum—whether fixed or tunable—remains the most effective strategy.
