Growing Eggplant With Grow Lights

Eggplant is a cornerstone of European and Middle Eastern cooking. The flavor from a fresh eggplant is hard to beat.
Eggplants can do very well under grow lights. Like most taller, fruiting plants they’re a little more demanding that leafy greens.

Eggplant Light Requirements

Eggplant plants will thrive under lights that provide:

20

30

 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 Eggplant

Eggplant plants do best with a lights on for:

Best Grow Lights for Eggplant

16 hours of light is a pretty good target for eggplant — particularly if they’re in your living space and you like to sleep.

You’ll need a fairly powerful light to provide 20-30 DLI in a 16 hour period. The Bright Grow recommendation is the GE 24″ LED Fruit & Flower Fixture. Hang the light just three or four inches above your leaves — raising it to stay just at that distance as the plant grows. This will give an optimal amount of light directly under the footprint of the lamp.
Eggplant, like all fruiting plants, will grow best under a light that's heavy on the red parts of the spectrum. A "fruit and flower" LED grow light is a good choice for growing Eggplant. High output fluorescent bulbs can work too but they generally provide less of the important red wavelengths.

Temperature for Eggplant

Higher growing temperatures help eggplant to develop flowers and fruit.

Germination: 

75

 – 

90

°F 

Growth: 

65

 – 

85

°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.
