Supplemental Red Light for Flowering and Fruiting Crops
Deep red light is widely used in horticulture because plants absorb it efficiently for photosynthesis. Supplemental red LEDs can be useful when they are balanced with the full spectrum fixture.
Quick Answer
Red light can support crop performance, but balance is essential.
Adding 660 nm deep red may help increase photosynthetic efficiency and support flowering or fruiting programs. However, too much narrow red without blue and broad white light can create poor plant shape or difficult crop inspection.
Supplemental red should be selected according to crop target, base spectrum and PPFD plan.

When supplemental red makes sense
| Use Case | Reason |
|---|---|
| Flowering crops | Can support photosynthetic activity and crop response. |
| High-output rooms | Allows spectrum tuning around a strong full-spectrum base. |
| Research or OEM projects | Supports recipe development and product differentiation. |
