11 Tips for Growing Lettuce Indoors In Containers

Don’t be surprised! Growing lettuce in containers is easier than you think! Lettuce has a short term but plentiful yield and requires minimal care. You will only need a standard potting soil, a little bit of water and plenty of sunlight.

Lettuce is so easy to grow that people consider it as an ideal indoor plant to grow for first-timer-gardeners.

Take a look at the tips on how you can successfully grow lettuce in a container.

Tips for Growing Lettuce Indoors

1. Choose a Plastic Pot that’s Medium Sized

A medium sized pot should be enough room for the lettuce to grow well.

If you decide for a clay pot consider lining the pot with a plastic bag before planting the seeds. Also, make some holes in the plastic bag to allow water to drain.

It is important for the container to have drainage holes. The holes will allow for any excess water to escape.

2. Clean the Container Properly

Make sure you thoroughly clean your container before planting. This especially goes for recycled containers that were previously used to grow different plants. Insect eggs and bacteria might still be living somewhere in the container, so it is necessary to make sure your container is very clean.

3. Choose a Standard Potting Soil

Standard potting soil works great for lettuce. Just make sure to avoid using dirt coming from your garden. This may have bacteria, insects and diseases that could potentially harm your crop.

4. Scatter a Dozen Lettuce Seeds When Planting

Sprinkle about a dozen or two lettuce seeds all over the container with soil. Avoid dropping so many seeds in one area. Then, pinch each of the seeds with your finger. Don’t worry, you don’t have to get all the seeds, a few would be enough to grow the lettuce. Pour some more soil over the seeds. Cover the seeds with only about ¼ inch of the potting soil.

5. Use Spray Bottle to Spritz Water to the Seeds

Spray water to your seeds by using a spray bottle, but be careful not to overdo it. Mist the seeds every morning as well. When growing lettuce indoors, the soil must remain moist continuously in order for it to germinate.

6. Water the Plant Every Other Day

Frequent watering is important when growing lettuce. If you are unsure whether your soil needs water or no,  check the soil very frequently. Stick your fingertip at the top of the soil. If it’s dry, then the plant needs watering.

7. Keep the Lettuce Plant Cool

Keep the lettuce plant cool at all times. The ideal temperature is between 60 and 70 degree Fahrenheit. You should lower the temperature at night by around 10 degrees.

8. Place the Plant Near the Window

As I mentioned above, light is necessary when growing lettuce in containers. Seedlings must be placed near the sunniest window in your house. They require up to 16 hours of sunlight in order to give you the bushiest and most delicious lettuce.

9. Invest in a Fluorescent Light for Growing Plants

If you cannot provide enough natural light to your lettuce, make sure you invest in a fluorescent light for your plant. Let the seedlings to stay there for up to 14 hours. Once this time has passed, make sure to turn off the light.

10. Use Mild Fertilizers

If necessary, use mild fertilizer. Lettuce won’t mind it. Mix the fertilizer with equal parts of water in order to cut down its strength to half. Apply it directly to the seedlings at least once a week and then eventually decrease its use.

11. Harvest Loose Leaf Lettuce All At Once

Once the lettuce leaf reaches the size to your own liking, start harvesting the leaves. Harvest the loose lettuce leaf at once. Leave out the inner leaves so they will be able to develop more.
