Quick Answer

Microgreens do not need direct sunlight to grow. In fact, they can be grown indoors under artificial light or in a partially shaded outdoor area. However, they do need some light to grow, and it’s best to place them in a well-lit area that receives at least 4-6 hours of indirect sunlight per day.

Microgreens have become increasingly popular in recent years. Their small size, vibrant colors, and unique flavors make them a great addition to any dish. But do microgreens need sun? Are they able to grow without direct exposure to sunlight? I’m sure you’re curious to find out the answer!

In this article, we’ll explore whether or not microgreens require direct sunlight in order to thrive. We’ll look at what makes these plants so special and how they can still be grown even if there’s no access to natural light. Finally, we’ll discuss some tips for growing your own healthy crop of microgreens indoors.

So let’s get started! If you’ve been wanting to start growing your own microgreens but weren’t sure where to begin, then keep reading – this is the perfect place for you!

Definition Of Microgreens

What are microgreens? They’re young edible plants, harvested at the cotyledon stage. That means they have their first set of true leaves and a few secondary ones – but not yet fully developed foliage. Microgreens are usually 1–3 inches tall and very delicate in texture. They add flavor, color, and nutrition to salads, soups, sandwiches, smoothies and more!

But do microgreens need sun for growth? The answer is yes – light is essential for healthy plant development. However, there’s a bit more nuance than that when it comes to growing these mini-veggies. In this article we’ll explore just what light requirements microgreens need so you can successfully cultivate them yourself.

Let’s start by looking at some common types of lighting used in indoor cultivation: artificial lights like LED grow lights as well as natural sunlight streaming through windows or glass doors. Both options provide different benefits depending on your setup and needs; understanding how each works will help you make an informed decision about which one best suits your project. And with that knowledge in hand, let’s move on to discuss the specific light requirements needed for healthy microgreen growth…

Light Requirements For Growth

So, what light requirements do microgreens need for healthy growth? To answer that question, it’s important to understand both the types of lights available and their individual benefits. Here are three key points to consider:

  1. Artificial lighting such as LED grow lights offer more control over how much and what type of light your plants receive. This can be beneficial in achieving consistent results when cultivating indoors.
  2. Natural sunlight has a broader spectrum than artificial lighting, providing essential ultraviolet (UV) rays which play an important role in photosynthesis and plant health.
  3. Different varieties of microgreens require different amounts of light; some need direct exposure while others can thrive with indirect or diffused illumination.

Ultimately, the best way to ensure proper light requirements is through experimentation – seeing which setup works best for each variety you’re growing. With these tips in mind, let’s move on to discuss the specifics of growing microgreens indoors…

Growing Microgreens Indoors

Growing microgreens indoors can be a great way to enjoy fresh produce year-round. With the right setup, you can provide your plants with all the light and nutrients they need without having to worry about environmental factors like pests or extreme weather conditions.

When growing indoors, artificial lighting is often used as it offers more control over how much and what type of light your plants receive than natural sunlight does. LED lights are typically recommended for their efficiency in providing just the right amount of illumination for healthy growth. However, if you have access to direct sunlight, such as from windowsills or balconies, some varieties of microgreens may still benefit from exposure to UV rays.

No matter which type of lighting you choose, make sure that there’s enough space between them and the plants so that they don’t become too hot and scorch your greens. Also remember that different types of microgreens require different levels of light; adjust accordingly based on what works best for each variety! From here we’ll look at the specifics of choosing the correct types of lighting…

Types Of Lighting To Use

Stepping into the realm of growing microgreens indoors, it’s essential to understand the different types of lights available and how they can benefit your plants. With proper illumination, you can give your tiny greens just what they need for vibrant growth!

When selecting lighting options, LED lamps are a great choice as they’re energy efficient and provide an even spread of light without getting too hot. If you have access to direct sunlight from windowsills or balconies, some varieties of microgreens may also benefit from exposure to UV rays. However, make sure that there is enough space between them and the plants so that the intense heat doesn’t scorch your tender leaves.

No matter which type of lighting you use, remember that each variety of microgreen requires its own specific level of illumination; adjust accordingly based on what works best for each one! Ultimately, by providing adequate light sources with careful consideration given to their placement in relation to your plants, you’ll be able to achieve healthy growth in no time at all. Now let’s take a look at some of the benefits that come along with introducing natural sunlight…

Benefits Of Sunlight

Sunlight is one of the most important components to growing healthy microgreens. Not only does it provide essential vitamins and minerals, but its natural warmth helps speed up germination time and encourages photosynthesis for faster growth. Plus, its UV rays can help keep pests away!

Using sunlight in combination with artificial lighting is ideal as you’ll be able to enjoy all these benefits while also having control over when and how much light your plants receive. With careful positioning, you can move your trays or shelves around throughout the day so they get just enough sun without being exposed too long – this way, you won’t have to worry about them getting burned or dried out if left unattended.

Along with keeping an eye on their location, make sure that each variety of microgreen is receiving enough hours of direct sunlight per day; typically 4-6 hours should do the trick depending on what type of greens you’re cultivating (check instructions for specific requirements). If necessary, consider investing in a timer switch so you don’t forget to turn off the lights at night – this will save energy as well as prevent any potential heat damage from occurring. All in all, following these simple steps will ensure lush growth and plenty of nutrients for your tiny veggies!


So, do microgreens need sun? The answer is a resounding yes! Sunlight offers many benefits for growing these nutrient-dense greens. From providing the necessary light to grow and thrive, to supplying them with essential vitamins and nutrients, sunlight can make all the difference when it comes to successfully growing your own microgreens.

If you don’t have access to natural sunlight or want to start growing indoors, there are plenty of artificial lighting sources that will work just as well. With so many options available, anyone can get started on their own indoor microgreen garden with ease.

When considering whether or not microgreens need sun, remember that this special type of plant needs lots of bright light in order to reach its full potential. So why not try out some DIY indoor gardening and see what kind of delicious harvest you can reap? After all, isn’t home grown produce always the best?
