How to Grow Lettuce Indoors?
We know lettuce plants can be grown inside the house. But, do you have an idea how you will plant lettuce plant indoors? How much light does lettuce need to grow indoors? No? Well! What if we say, no need to worry because we have your back?
Yes, you heard it right, from our personal planting experience and studies, we will guide you on how you can also plant lettuce indoors easily. For your reference, we have jotted down a basic step-to-step guide, which will help you to plant your favorite lettuce variety at home easily. Let’s get started.
1. Choose Indoor Growing Space
It’s very important to select a corner in the house, which will suit your lettuce plant to grow and thrive. From our experience and research study, we will advise you to go to the house corner, which receives the most sunlight. Generally, a south-facing corner or window is the best option to plant your lettuce, then it doesn’t matter which variety you are planning to grow.
Note: It’s true, that lettuce requires sunlight, but that doesn’t mean you will give them scratchy sun rays. No! Doing so will only cause sunburn issues to your plant. Plus, if your house doesn’t receive bright sunlight, then go for an LED grow light, it will also help you to grow your plant successfully.
2. Take a Pot to Grow Lettuce Indoors
Once you are sure of which variety you want to plant, you need to select an appropriate container or pot for your lettuce plant. It’s important to select the best container for your plant because lettuce has shallow roots. So, we recommend you medium-sized pot with a good drainage hole, will be the best choice for them. Plus, if we talk about the container material, then plastic is the most suitable one as compared to any other materials available in the market.
After selecting the appropriate container, the next step is to fill the pot with good quality seed starting mix because they are lightweight, and, allow your plants roots to grow well. If in case, you do not find a good quality seed mix, you can prepare one at home also. You just need an equal proportion of peat moss or coir, vermiculite, and sand, and here you are ready with the seed mix.
3. Plant Your Lettuce Seeds in a Pot
After filling a pot with seed starting mix, now it’s time to plant your lettuce seeds or seedlings. For that, you need to dig up around 1/4-1/6 deep hole, and then keep the seeds inside the pot. Make sure each pot contains maximum 4 seeds only, do not overcrowd it. After that, sprinkle seed mix on the top followed by sprinkling water through a mist bottle, then with a light hand press the soil to give a finishing touch.
4. Water the Seeds With a Mist Bottle
One of the best way to grow lettuce indoors is by using a mist bottle. Yes, you heard it right, instead of watering cans, use mist bottles to water your lettuce plants. It will help you to keep the soil moist and not waterlogged. So, when you notice seeds or seedlings start to sprout, sprinkle water via mist bottles daily. In addition, you can check the soil by inserting your fingers in the soil, if you feel it’s dry you can sprinkle water accordingly.
5. Place Your Lettuce Plant Under Right Light
To grow healthy and thriving lettuce plants, you need to provide them with a moderate temperature, where they can easily survive. As per personal experience, we have observed that lettuce grows best at temperatures around 65 degrees. Since you are planting this indoors, we suggest you place it near the window when the outside weather is pleasant. In fact, placing your plant near a window or LED grow light will only add a thriving touch to your plant.
However, if you live in a place, where you receive very little sunlight, then it would be best if you purchase a good LED grow light for your lettuce plant care. This is because your lettuce needs at least 12 hours of direct sunlight daily to thrive.

6. Harvest Your Lettuce Plants
It has been observed that you can harvest your lettuce plant, tentatively, after 40 days of planting. Plus, lettuce indoors is continually growing, so you can harvest it regularly depending upon your usage.
For instance, if you wish to add lettuce to your food or salad, then make sure you cut it early in the morning. This is because, during this period, lettuce plants are the most hydrated one, and will give a healthy leaf. However, if in case you miss out on harvesting in the early morning, then we suggest you skip that day. Because mid-afternoon or evening is not an appropriate time for harvesting.
Furthermore, it is recommended to not harvest all plants in one go, it would be best if you cut down 4-5 outer leaves. You can store them in a refrigerator, then use it as per your preference. Plus, avoid cutting or picking lettuce’s crown, as it will impact its growth.
Note: Mark the harvesting date on your calendar, and then wait for at least 2 weeks to harvest it again. This is because generally, lettuce plants take 2 weeks to heal and grow more.
