Yes, vegetables can be grown indoors all year round. Most of the edible plants that you can grow outside will thrive in the right conditions inside.

In fact, the majority of vegetables are grown indoors in some form or fashion, most often in a greenhouse. But most of us don't have a greenhouse, so how do we successfully grow our vegetables indoors? There are a few tips to follow to ensure a healthy garden. Just keep reading, and we'll answer some additional questions you might have about growing vegetables indoors.


The Right Amount Of Light

The number one thing your indoor vegetable plants need to blossom is light. It sounds simple enough, but as the seasons change, natural light levels diminish. Even the sunniest spot in your home will see less daylight in the short days of winter. Vegetable plants need as much as 14 hours of light, if not more.

As we said, the majority of vegetable growing operations are in greenhouses, but a greenhouse isn't an option for most. Luckily, there's a solution: grow lights. Grow lights allow you to pump up the light available to your indoor garden.

Choosing the size or type of grow lights you need depends on your space and how many plants need light. For a smaller space, you can hang a full spectrum 25W LED grow light with a panel size of 9.9 x 4.68 inches.

Can Any Vegetables Be Grown Indoors?

Just about any vegetable can be grown indoors. Available space will likely be the most significant factor in what you will be able to grow indoors. Keep in mind that some plants like carrots need deep containers of soil while others like butternut squash have vines that need to spread wide.

Here is a list of popular vegetables that can be grown indoors all year long.


Tomatoes should be started inside from seeds at the end of summer. You can undoubtedly begin to sow seeds any time of the year, but tomatoes peak outdoors in the summer. Extend the growing season indoors and plant seeds in September.


Carrots grown outside are best when harvested in the fall or spring. To keep carrots growing year-round, plant them inside as winter begins or springs ends. Plant your seeds biweekly to have carrots flourishing throughout the year. And lastly, choose a variety that doesn't have a deep root system for best results.


Kale likes chilly weather. This cold-hardy vegetable is planted outdoors in spring and fall. To grow your own indoors, plant seeds at the beginning of summer.


Cauliflower is another cool-weather crop. It grows outdoors in the chillier months of spring and fall. Start planting your seeds toward the end of spring.


Cabbage grows in the fall and spring. With its long growing season, it's accustomed to a range of temperatures. Start planting your seeds indoors mid-fall.


Radishes have shallow root systems and will grow well indoors. This plant prefers cold weather, so planting seeds in spring or early autumn is ideal.

Fill small planting containers or flats with about 4 inches of planting mix. Scatter then cover your seeds with the mix, keeping them about an inch apart. You can start harvesting baby lettuces in as little as three weeks.
