Growing Peas With Grow Lights

It’s hard to beat the taste of peas straight off the bush. They might not even make it to the plate — they’re so snackable.
Peas can grow well indoors if you select the right variety give them enough intense light.

Peas Light Requirements

Ideally begin with 12 hours of light to boost foliage. Once your plant is well established ramp up to longer days to encourage flowering and pod development.

Peas plants will thrive under lights that provide:

15

20

 DLI 

DLI (Daily Light Integral) is how we measure amounts of “plant-useful” light. Once we know a plant’s DLI needs we can match it to the ideal grow light setup.

Day Length for Peas

Ideally begin with 12 hours of light to boost foliage. Once your plant is well established ramp up to longer days to encourage flowering and pod development.

Peas plants do best with a lights on for:

12

18

 hours 

Best Grow Lights for Peas

It takes a moderately powerful light to provide 15-20 DLI in a 12 hour period. The Bright Grow recommendation is the GE PAR38 balanced grow bulb. Hang the bulb 14-16 inches above the plant’s leaves. This will give you a circle of light 8-9 inches across that’s just the right amount of bright.

Peas, 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 Peas.

Temperature for Peas

Skip the heat mat when germinating peas — it can cause failure to germinate or lead to week seedlings.

Germination: 

40

 – 

85

°F 

Growth: 

50

 – 

70

°F 

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.
