How to Grow Indoor Lettuce

When the days grow short and the garden is over for the summer, move the vegetable garden indoors to continue growing fresh vegetables year-round. Just because it is winter, does not mean a gardener's green thumb cannot continue to cultivate and harvest fresh vegetables. There are a variety of vegetables suitable for indoor growing. Lettuce is one of the easier vegetables to grow indoors due to its shallow root system and the ease of harvesting the fresh leaves.

Step 1

Make five or six 1-inch long slits in the bottom of one of the plastic trays for drainage. Fill this tray to the top with potting soil.

Step 2

Sprinkle the entire surface of the potting soil with lettuce seeds. Dust a very light layer of potting soil over the seeds.

Step 3

Spray the surface of the potting soil lightly with the spray bottle. Place the other plastic tray over the top as a lid.

Step 4

Place the tray under the grow light and keep it there with the light shining for up to one week. Spray the surface of the soil daily to keep it moist.

Step 5

Remove the top tray when the seeds sprout and place it under the bottom tray as a saucer to catch moisture. Keep the soil moist by spraying it daily. Provide at least 12 hours of light each day.

Step 6

Cut a harvest of lettuce within one month by snipping the leaves down to just above the crowns. Place the tray back under the grow light again and continue to grow and harvest the lettuce.
