Growing vegetables indoors is a great way to increase the amount of fresh produce you have access to all year. Lettuce, in particular, is one vegetable that can be grown easily and affordably at home. This article will teach you how to grow lettuce indoors so that it’s always on hand for salads or sandwiches!
You can grow vegetables indoors, and lettuce is one of the easiest!
If you’re tired of having to buy lettuce every time you want a salad or sandwich, growing your own is an easy way to ensure that fresh produce is always available. You don’t need to have a large outdoor vegetable garden either, you can grow inside with a tiny pot.
With food costs soaring (especially fresh produce) growing your own organic lettuce is an easy solution to ensure you have fresh greens in your diet without paying an arm and a leg at the market. Plus, there’s nothing like the taste of fresh produce you grow yourself!
You can even grow lettuce on a windowsill in the dead of a Canadian winter!

What are the best lettuce varieties to grow indoors?
There are three different types of lettuce you can grow indoors: leaf, head, or romaine. Each has its own pros and cons- read on to figure out which one is right for your growing space!
Leaf lettuces come in many varieties (green oakleaf, red salad bowl, green iceberg). Fluffy leaf lettuces are your best bet if you are growing lettuce in a hydroponic or aeroponics system. They are more forgiving when it comes to lack of nutrients and consistent light exposure, making them easier to grow indoors for beginners. One downside is that they do not last as long as head lettuces- but leafy green salads can be made with these varieties.
head lettuces are one of the most popular types of lettuce. They are easy to grow indoors, but they will only last about one month if you keep them growing indoors- so plan on doing frequent re-plantings with this type.
Romanesco varieties have some disease resistance but can be a bit more challenging to grow indoors.
There are smaller varieties however that do exceptionally well in small containers indoors. We especially love Little Gem. This is a small romaine type that grows well in containers and has very few problems with disease. It’s also delicious and my absolute favorite lettuce to grow indoors. One head is perfect for a personal full-size salad.
What size pots are required?
You can plant your lettuce in a variety of different size pots, but at least one that is approximately three inches deep to grow it indoors.
You do not need very deep containers to grow lettuce, and anything deeper than 3 inches is really a waste of space and soil.
What Type of Soil do you need for lettuce?
Use a good quality potting mix. It shouldn’t contain any fertilizer because too much nitrogen will cause your lettuce to bolt (go to seed).
The soil should be loose and not compact. You don’t want to pack it down or you will have a hard time watering the plants
How Much Water do your Lettuce Plants Need?
Lettuce is one of those plants that doesn’t need much water once established. The soil should always be moist, but never soggy wet
If your soil is dry you should water it, but if the leaves start to wilt, wait until they recover before watering again.
Do Your Lettuce Plants Need Sun?
Lettuce plants need at least six hours of full sun a day. Some varieties are better suited for shade and can tolerate partial shade. The best varieties for growing indoor without additional artificial light are those that mature quickly and do not produce a long stalk.
How long does it take to grow lettuce indoors?
How long does it take to grow lettuce indoors? You can expect your first harvest about four or five weeks after planting seeds. The plants will continue producing new leaves every two weeks, but you’ll want to keep picking the outer ones regularly so that they don’t get bitter and tough.
Lettuce can be picked throughout its growth, so you don’t have to wait until it is fully grown up before eating your harvest.
Growing Lettuce Indoor is Easy!
If you’ve been looking for a way to grow your own lettuce and haven’t had much luck with outdoor gardening, the answer may be as simple as growing it indoors. Lettuce is one of those vegetables that can surprisingly produce quite well in many types of climates – even inside!
In fact, many people grow lettuce indoors all year round and never have to buy it again.
