Best Grow Lights for Oregano

It takes a pretty powerful light to provide 20-30 DLI in a 12 hour period. That’s what’s needed though. The Bright Grow recommendation is the GE PAR38 balanced grow bulb. Hang the bulb 12-13 inches above the plant’s leaves. This will give you a circle of light 8 inches across that’s just the right amount of bright.

Oregano, like other leafy plants, will thrive under a balanced full-spectrum light.

Balanced full-spectrum lights provide roughly equal amount of red and blue wavelengths while still appearing white to our eyes.

High Output fluorescent or LED grow lights will both work well for growing Oregano.
