How Do You Plant Lettuce in the AeroGarden?

Once you have chosen which lettuce variety to grow, it’s time to plant your seeds. If you have used your AeroGarden before, then you will need to sanitize your garden first. After that, the steps will be the same as using a newly bought model.

Plant lettuce indoors with your AeroGarden by following these steps:

  1. Fill your AeroGarden water bowl with either distilled or tap water up to the “Fill to Here” indicator. The use of hard or softened water is not advisable.
  2. If you own an AeroGarden model that has the “Plant Select” feature, choose “Salad Greens” as the plant type.
  3. Check the Liquid Plant Food bottle for the right amount to use. Pour it in and let your plants soak up the goodness. Don’t worry about feeding them again until you see the “Add Nutrient” reminder pop up. This usually happens after a few weeks. 
  4. Arrange your AeroGarden seed pods in the empty slots on the Grow Deck. Space the pods evenly and label them accordingly. Your kit should have instructions on where the pods should go. There are designated areas for taller and shorter plants.
  5. Place Grow Domes over each pod to lock in moisture and help with germination.
  6. Adjust the light to its lowest position.

Different lettuce seedlings take different amounts of time to grow. The germination time for salad greens usually takes 5-8 days.

How Do You Grow and Tend to Lettuce in the AeroGarden?

Fresh lettuce is one of the quickest plants from seed to harvest that you can grow in your indoor garden. Follow the tips below to enjoy a steady supply of this crop’s green leaves for months!

  1. Remove Grow Domes – Once you see plants start to emerge from the holes in the seed pod label, it is time to remove the domes. This is best done after the lights have turned off to avoid stressing the plant.
  2. Keep the Garden Watered and Fed – Always ensure that there is plenty of water and enough nutrients in the water tank. Nutrients should be replenished every two weeks while water levels should never go below the indicator.
  3. Maintain a Cool Temperature – Lettuce thrives in cooler temperatures, ideally between 60°F (15°C) to 65°F (18°C). When temperatures rise from 70°F (21°C) to 80°F (27°C), lettuce may start bolting. This can make your AeroGarden lettuce bitter. Make sure to keep an eye on your plant if you place it near sunny windows.
  4. Grow Lights – A general rule of thumb is to place the lights 6-8 inches above the tallest part of your plant. Some plants like herbs need higher light levels so you can do 3 inches.
  5. Trimming Your Plant – Remove brown or dead leaves at the base of the plant by using sanitized scissors. Regularly trim outer leaves to encourage new growth and prevent overcrowding as well.

Most lettuce and salad greens last about two months, with some varieties stretching to three months. Keep an eye out for signs that your greens are nearing the end of their life cycle. Have you noticed a bitter taste creeping in? Or maybe you’ve spotted some flowers starting to form? These are telltale signs it’s time to start a new batch.

How Do You Harvest Lettuce in the AeroGarden?

Lettuce is a plant that keeps on giving. If harvested properly, you can enjoy your lettuce plants for months on end. 

Here are some tips for harvesting lettuce:

  • Harvesting mature lettuce can start 21 days after germination.
  • I like to start harvesting my plants when they have about six leaves.
  • Grab some clean scissors or snips. Always use clean tools when cutting your plants. It helps prevent the spread of diseases.
  • Cut a couple of the lower, outer leaves from each plant to ensure lettuce yields in AeroGarden increase.
  • Only take about a third of the plant at most. 
  • Spread your harvest out among all your plants.
  • Continue to remove brown and dead leaves from around the base of the plants to avoid molds.

Remember, patience is key. Your plants will reward you with continuous growth if you treat them right.

AeroGarden Lettuce FAQs

1. When Should I Harvest My AeroGarden Lettuce?

Growing lettuce in an AeroGarden is quick and easy. After just 3 weeks, you can start picking some leaves. By week 4, your lettuce will be fully grown. Want to know when it’s ready? Look for leaves about 4 inches tall. That’s your cue to start harvesting.

2. How Do You Cut Lettuce off Your AeroGarden?

When harvesting lettuce, you’ve got two options. First, you can snip off whole leaves. Grab your scissors or shears and cut right at the base of the leaf. The second method is my personal favorite. Take your scissors and trim just the top third of the leaves. Easy, right?

3. How Do You Harvest Hydroponic Lettuce So It Keeps Growing?

You can regrow most lettuce types multiple times. Just cut the outer leaves when you harvest. This lets the core and roots keep growing. With careful harvesting, you’ll get three to five harvests from each plant.
