Lighting Requirements For Growing Microgreens

Now that we understand what microgreens are, it’s time to discuss the lighting requirements for growing them. When choosing a light source for your microgreen crop, there are several key factors you must consider: light intensity, duration and environment.

The amount of light needed for successful growth depends on the type of microgreen being grown as well as environmental conditions such as temperature and humidity. Generally speaking, most types of microgreens require between 10-20 hours of light each day with an average intensity level between 200-400 lux. The exact timing and intensity will vary depending upon the particular variety of microgreen being grown and should be adjusted accordingly based on trial and error results.

In addition to providing adequate light levels, it is important to also maintain a consistent light cycle throughout the entire growing period in order to ensure healthy development and prevent any potential problems from occurring due to sudden changes in illumination or darkness.

To achieve this consistency, many growers opt for using LED grow lights which offer more reliable performance while consuming less energy than other traditional options like fluorescent lamps or HID systems. Furthermore, LED fixtures can easily be programmed to provide specific amounts of light at various times during the day without having to manually adjust settings every few hours.

Providing proper lighting is essential when it comes to achieving good yields with microgreens; however, ensuring suitable temperatures and humidity levels are met is just as critical in order for plants to thrive. With that said, next let’s take a look into different types of grow lights available today so you can find one that best suits your needs.

Types Of Grow Lights

When it comes to growing microgreens, choosing the best light is essential. There are several types of grow lights available, each with its own advantages and disadvantages.

LED grow lights are a popular choice for indoor growers because they produce relatively low heat, making them energy efficient and easy to maintain. They also come in a variety of colors so you can customize your lighting setup to fit your needs. However, LED lights have limited coverage area and may require additional fixtures if you want to cover large areas.

Fluorescent grow lights work well for smaller spaces as they provide intense illumination over shorter distances. They’re inexpensive compared to other options but require frequent bulb replacement due to their short lifespan. HPS (High Pressure Sodium) grow lights emit more yellow-orange light than fluorescent bulbs and offer better penetration into leafy plants like microgreens. These lights are long lasting but generate quite a bit of heat which could be an issue indoors. Finally, ceramic metal halide grow lights are ideal for larger grows as they create bright white light that covers wide areas while still maintaining good efficiency levels at lower temperatures.

So there’s no one size fits all when it comes to choosing the perfect light for growing microgreens – instead consider what type of space you’ll be using, how much coverage you need, and whether or not temperature control is important before settling on a particular option. From here we can move onto understanding how to make sure we’re selecting the best possible light for our specific needs and goals.

How To Choose The Best Light For Growing Microgreens

Did you know that nearly 90% of microgreens are grown indoors? With this in mind, it is essential to consider the lighting environment when choosing the best light for growing microgreens. Here’s how:

  1. Consider the types of lights available: LED grow lights, fluorescent tubes and CFL bulbs can all be used to provide a suitable environment for your microgreen crop.
  2. Determine light intensity and duration: The amount of light required by your crops depends on their stage of development as well as whether they are planted in soil or water. Generally speaking, higher intensities are appropriate during germination and early stages whereas lower intensities may be sufficient later on. It’s also important to take note of the number of hours per day that plants should receive exposure to light. As a general guide, 8-12 hours will suffice for most varieties.
  3. Evaluate energy efficiency: When selecting a grow light it’s important to think about cost effectiveness and environmental sustainability. LEDs tend to have longer lifespans than other types while still providing ample brightness which makes them an ideal choice if you’re looking to save money over time and reduce your carbon footprint at the same time!

Overall, there are several factors to consider when deciding on the right type of light for growing microgreens such as intensity, duration, energy efficiency and cost effectiveness – all of which should be taken into account before making any final decisions. Doing so will ensure that you create a healthy environment for your plants while keeping costs down too!

Determining Light Intensity And Duration

Now that we know how to choose the best light for growing microgreens, let’s move on to determining light intensity and duration. Light intensity is important because it directly affects the rate of photosynthesis, which in turn influences microgreen growth. The optimal lighting for a particular type of microgreen will depend on its individual needs – some thrive with higher levels of light while others may require less intense conditions.

When choosing a grow light system, consider both the light spectrum and intensity needed to achieve optimal results. Different wavelengths are necessary for different stages of plant development so make sure you select one that provides the right amount of red and blue spectrums your plants need in order to flourish. It’s also important to ensure that the unit emits enough lumens or lux (a measure of brightness) to provide sufficient illumination over your planting area.

In addition to selecting appropriate lights, you’ll also need to figure out an ideal length of time each day that your plants should be exposed to them. Most vegetables will do well with 14-16 hours per day but this can vary depending on their specific requirements. If possible, try experimenting with different days/hours until you find what works best for your particular crop.

Once you’ve determined the correct level of intensity and duration for your chosen variety, it’s time to set up the grow light environment!

Setting Up The Grow Light Environment

Creating the right environment for microgreens is essential to ensure healthy growth and development. It’s important to have the correct grow light fixtures, stands and ambient temperature. Additionally, one should pay close attention to how the lights are placed and what type of reflectors are used when setting up a growing area.

Grow light fixtures come in various shapes and sizes. The size of the fixture will depend on how much space you want to cover with your plants. They require specific wattages that can be adjusted according to your needs. Furthermore, it is essential to choose a fixture that has adjustable heights so that you can adjust the height as needed during different stages of plant growth.

When choosing where to place the grow light stand, consider both temperature and lighting requirements when making this decision. If possible, set it up near a window or other source of natural sunlight while also keeping it away from direct sources of heat such as radiators or air vents. Also keep an eye on nearby windowsills—they might get too hot if not adequately covered by curtains or shades! Finally, using reflective material like aluminum foil around your grow light stand helps redirect some of the wasted energy back into your crops which can result in more efficient use of resources overall.

In short, proper setup for optimal growing conditions includes selecting appropriate grow light fixtures, stands and reflectors; finding suitable locations; paying attention to ambient temperatures; and taking advantage of any available natural sunlight. With these tips in mind, anyone can create their own ideal environment for growing microgreens at home!


It’s no surprise that growing microgreens takes a bit of finesse and know-how. With proper lighting, you should be well on your way to producing some of the best greens around! After all, why go through all this trouble if you don’t get the results you want? So, let me leave you with one final thought: You can have the most perfect grow light setup in the world but without my green thumb it won’t make much difference…just saying.

Now I’m not telling you what kind of light to use for growing microgreens – only YOU can decide which is best for YOUR needs. But do yourself (and your microgreens) a favor by doing some research beforehand and learning about different types of lights and how they interact with plants. That way, when it comes time to set up your own environment, you’ll know exactly what works best for you.

Finally, keep in mind that there is no single “best” light for growing microgreens – it really depends on your individual needs and preferences. The key is to experiment until you find something that works well for both you and your plants. Good luck!
