Growing Lettuce in an AeroGarden


Did you know that growing lettuce in an AeroGarden at home is much higher in vitamin C than Lettuce bought from the supermarket or organic shops? Well, it is; growing Lettuce in your AeroGarden has almost 300% more vitamin C. 

Aero gardening is also a great indoor activity for children. Growing Lettuce in an AeroGarden is a fantastic way to get your children involved and use the leaves to make their salad sandwiches. Children will see the seeds sprout and get their first leaves, then their real leaves, and grow to harvest—what an excellent activity for the whole family. 

Your Lettuce will sprout, grow and be ready to harvest from three weeks onwards. After that, you will have a steady supply of leaves, full of nourishment, washed and ready for your plate or salad bowl.

Growing Lettuce in an AeroGarden sounds excellent, but where did Lettuce originate?

The origin of Lettuce

I have grown up loving Lettuce since I can remember; what I didn’t know was that Lettuce (Lactuca sativa) is an annual of the daisy family Asteraceae nor did I know where it originated! 

It all began in Egypt

As recorded about 2700 BC on the Egyptian walls, there are hieroglyphics of min, the God of fertility. It is a prevalent food among the Egyptians. Ancient Egyptians were the first to cultivate it from a weed. The Egyptians produced oil from the seeds gathered from Lettuce once it had flowered and produced seeds.

The Lettuce has a thick stem that grows erect with leaves and has milky sap and used as a

  • Sacred food
  • Having sexual connotations
  • Increased stamina
  • Used in cooking
  • Mummification

The Egyptians were the first to grow the Lettuce and making it less bitter and nicer to eat. Served in the 6thcentury BC to Persian Kings, according to Herodotus.

The Greeks

The Egyptians taught the Greeks how to grow Lettuce which they used for

  • Medicinal purposes
  • Sedative
  • Served as a salad
  • Eaten before meals to aid digestion
  • Mentioned in Greek Mythology, Aphrodite’s lover Adonis died in a bed of Lettuce, killed by a boar
  • Associated with male impotence
  • Used at deaths and funerals

The Romans

The Romans called Lettuce Lactuca, which means “milk” of the white sap. Like the Greeks, they too associated Lettuce with sexual potency, and it increased sexual stamina, other qualities of Lettuce included:

  • Medicinal purposes
  • Serve as a salad before meals to stimulate digestion
  • Sleeping aid when eaten in the evenings

It is said that Pliny the Elder in 77 AD. Produced several cultivars:

  • And Purple.

From Ancient Egypt to Space

Lettuce was transported around the world and from there into space. There is a lot more information on Lettuce and the taboos associated with overeating. For example, when British women first encountered Lettuce, they were too scared to overeat because they believed it made them barren.

The growing lights can be very bright, and sometimes we turn them off, forgetting that Lettuce loves lots of light for optimum growth. The lights need to be as low as possible because the more light Lettuce receives, the larger the leaves will grow.

Leaves can grow to a height of 6 to 12 inches (15 to 30cm)!


AeroGarden guarantees that their seed varieties, tested and they offer high-quality yields, flavour, colour and look amazing in your system.

Harvesting Lettuce

There are two ways you can harvest your Lettuce:

  1. The haircut is ideal for larger leaves, trim to 1/3 of the size with scissors or gardening shears—ideal for salads. You can prune this way at least 2-3 times per week.
  2. Single leaf cut is ideal if you want to pick one or two leaves for a salad sandwich or to garnish a meal. Cut the largest leaf as low as possible. Use your fingers, scissors or gardening shears. A good hint regarding your Lettuce is you should always wash your Lettuce in clean water before consuming.

Pruning back your lettuce leaves evenly, never have the lights too high or too low. The light should be just high enough to allow the light to reach the smaller ones, increasing their growth. The optimum height is 4-6” above the plants; otherwise, you may burn or get browning on your leaves.

It is essential to harvest your Lettuce early and regularly. The recommended number of times is two to three times per week after the initial third week.

The optimum temperature for growing Lettuce indoors

Lettuce loves cooler temperatures. If your house is too warm, your Lettuce will assume its summer and could run to bolt. It will flower and produce seed. Your Lettuce will be unsuitable for eating. 

The ideal temperature in your room for growing Lettuce is from 12.8 to 21 degrees Celsius (55-70 degrees Fahrenheit).

Can Lettuce be planted with other plants?

You can plant Lettuce with other plants such as herbs. It’s a great idea to mix them up. For example, if you have a six pod AeroGarden Harvest, you can plant three of your favourite herbs and three of your lettuces.

On a final note

Lettuce has undoubtedly come a long way since its early beginnings in Ancient Egypt growing in the wild. It was then introduced to the world and is now grown in space to be eaten by the astronauts. 

Today, you can select varieties that taste sweeter and have a buttery flavour than its ancestors that had a bitter taste. Growing Lettuce is found in the wild and growing in gardens and indoors in hydroponic or AeroGarden systems and space.

    Hi Yvonne,

    Thanks for this informative article showing us that we can grow lettuce at home and it’s indeed a good activity for children. It’s also helping you share tips about haircutting the leaves, the light, and the temperature. I think your readers can get great value from this article. 🙂


    • Yvonne says:

      Hello Matt, sorry for taking so long to reply to your comment. Thank you for responding, and I do agree growing lettuce in your own home is an excellent activity for the children. When haircutting the leaves, you need to leave behind 1/3 for continued growth. It’s a good idea not to cut too short. I’m so happy that you believe my readers will get value from my blog.

  2. C.N. says:

    Thank you so much for this incredibly insightful article, Yvonne! I absolutely love lettuce, and I definitely want it to be as healthy and as rich in as many vitamins and nutrients as possible. I am amazed to hear that growing lettuce in an AeroGarden can increase its’ level of Vitamin C by more than 300%! I have just recently started gardening, and I am excited to give the AeroGarden and AeroGarden lettuce a try! Great read! God bless you!

    • Yvonne says:

      Hello C.N., Thank you for responding to my post. Yes, I agree it’s hard to believe that lettuce does have a higher vitamin C content. I think the secret is that if you drink a very healthy drink full of vitamins, our bodies absorb it readily. I believe lettuce does the same when you provide water and nutrients. The roots readily absorb the goodness.

    It seems I made the right decision by clicking on this post. I really learned a lot.
    Thanks for the invaluable information and tips.

    I actually had no idea that the lights need to be as low as possible, otherwise the leaves will grow larger. That makes sense to me now because I do have an Aerogarden and I have noticed that but had no idea it was caused by the lighting.

    Also, I have a question, I’m actually growing lettuce and would like to purchase a few more units, so when exactly does Arerogarden usually run their best sales?

    • Yvonne says:

      Hi Warren,
      Thank you for stopping by and leaving a comment. If you go to AeroGarden, they have a subscribe button. If you click on that and provide them with the necessary details, they will send you information of specials that they are running. You could pick up lettuce seeds for half the price. The lights need to be 3-4 inches from the leaves as they grow.

    Hello Yvonne!

    Its a very interesting article about lettuces and aerogardening! I did not know that eating lettuces provided so much benefits.
    Its one of my favorite food and is included in almost every of my salads.

    I think I will have a try at aerogardening as the lettuce it produces definitely contain more nutrients than those sold in supermarkets.

    Have you tried growing tomatoes with it?

    Cheers for the great work:)

    • Yvonne says:

      Hi, Arnaud, thank you for your comment. I am currently growing herbs in my Harvest Elite. I want to try growing little tomatoes after the herbs have finished. I hope they will be more successful than me growing them in the garden.
