Best Grow Lights for Mint

It takes a moderately powerful light to provide 12-16 DLI in a 12 hour period. The Bright Grow recommendations are:
  1. GE PAR38 balanced grow bulb. Hang the bulb 18 inches above the plant’s leaves. This will give you a circle of light 10 inches across that’s just the right amount of bright.
  2. The GE 24″ LED Fixture is also a decent bet. Hang the fixture just 5 inches above the plant’s leaf canopy. This will give a strip of optimal light 5 inches wide the length of the fixture.

Mint, 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 Mint.

Temperature for Mint

For growing mint at warmer temperatures simply turn down the light a little.











Many plants germinate at lower temperatures and prefer more warmth for their growth. This is how plants have evolved — sprouting early in the spring when the days are cool and growing and producing as the days get longer and warmer.
