Microgreens Lights: Here Are the Best Ones in 2021!

Did you know that microgreens are considered superfoods?

Consuming microgreens regularly will improve your health and protect you against many diseases, including cancer and heart disease.

It’s so easy to grow your favorite microgreens at home. All you need is a suitable grow light.

We did a comprehensive research to find the best grow lights for microgreens. Below you’ll find our top five list of microgreens lights.

Light Needs of Microgreens

The right quantity and quality of light is key to the successful cultivation of microgreens.

Not any light can make your microgreens thrive, therefore choosing a suitable grow light for your plants is crucial.

Microgreens need good quantities of blue light and red light.

Blue light is important for the growth of plants’ foliage and stems, so it’s vital for microgreens.

New research suggests that blue light can also increase the levels of antioxidants in microgreens.

Another study shows that red and green light can boost antioxidant levels in microgreens as well.

So, although red light is mainly required by flowering plants, microgreens will also enjoy good amounts of it.

Besides blue, red and green light, microgreens can use some UV light. But in case you’re growing your microgreens in the kitchen or the living area, it’s better to avoid using grow lights that emit UV light. The lights we’ll show you below are all UV-free for that purpose.

To sum up, the spectrum of your microgreens light should be rich in blue light but should also contain good quantities of red and green light.

As for the overall light quantity, microgreens will thrive under moderate to high light intensity.

The higher light intensity your microgreens receive, the more flavor and nutrients they accumulate.

For that reason, the ideal light for microgreens should emit high quantities of light.

But it’s important to note that very high light intensity can damage microgreens.

That means you need to keep enough distance between your microgreens and the grow lamp.

Best Microgreens Lights: Top Five List

1. Viparspectra V300

Viparspectra V300, grow light

Viparspectra V300 is the perfect grow light for microgreens.

The device has an optimized light spectrum for microgreens that is very rich in blue light. The spectrum also has good amounts of red light and some green light.

Viparspectra V300 is a plug-and-play grow light that is very easy to use. You can hang it in the kitchen and grow your microgreens under it.

With a light output around 200 μmol/s, Viparspectra V300 has a coverage area around 3’ x 3’ (≈ 1m x 1m).

The overall light that Viparspectra V300 emits is purple, a feature that makes it problematic for some growers.

But the device retails at a very affordable price and it’s perfect for starters. You can get your Viparspectra V300 here.


Mars Hydro TS 600, grow light

Mars Hydro TS 600 is another great grow light for microgreens that is very simple to use.

The device is more efficient than Viparspectra V300.

Mars Hydro TS 600 has a light spectrum that is very rich in blue, red, and green light.

It has a coverage area around 2’ x 2’ (0.6m x 0.6m), lower than that of Viparspectra V300.

The device emits a sunlike light that doesn’t dazzle the eyes. So, if you consider purple light unpleasant, this device is more suited for you.

Unlike Viparspectra V300, Mars Hydro TS 600 uses no cooling fans, and this makes it noise-free.

But you can’t control the light intensity or spectrum of Mars Hydro TS 600. The design of the device is also somewhat unattractive.

That said, Mars Hydro TS 600 is an affordable high-intensity grow light (you can check its price here) that will make your microgreens thrive.

3. Fluorescent Grow Lamps

With the rise of LEDs, fluorescent grow lamps are no longer very popular, but they work for well microgreens.

In fact, the only reason we included fluorescent grow lamps in our list is because they are traditionally used by growers for microgreens cultivation.

Most indoor growers have been cultivating their microgreens under high-output T5 fluorescent lamps.

T5 tubes are the most efficient fluorescent lamps.

Fluorescent lamps emit most of their light in the blue spectral range, so your microgreens will enjoy high quantities of blue and green light.

One drawback of fluorescent lamps is that they’re less efficient than LED grow lights and they emit more heat.

But they’re still effective and affordable.

One of the best brands of fluorescent grow lamps is VIVOSUN. They sell a full T5 fluorescent lamp fixture that fits 4 bulbs and has a good coverage area (you can check its price here).

4. HLG 65 Quantum Board (QB)

HLG 65 QB grow light

Most growers use HLG Quantum Boards to cultivate heavy-flowering and fruiting plants, but one of the lower models, HLG 65 QB, is an excellent choice for microgreens.

HLG 65 QB uses 120 top-rated Samsung diodes that emit a very optimized spectrum of light for microgreens.

The device has a coverage area similar to that of Mars Hydro TS 600, but it has a higher efficiency rate.

HLG Quantum Boards are known for their high quality and durability.

However, HLG QBs need to be assembled by the customer, which isn’t feasible for everyone.

That said, HLG 65 QB is still an excellent light for microgreens. The light sells at a price higher than that of other grow lights on our list (check its price here), but with HLG, you get what you pay for.

5. GE PAR38 Grow Light Bulb (Balanced Spectrum)

GE PAR38 grow light bulb

GE LED grow light bulbs are perfect for indoor growers who are searching for more versatility.

Those bulbs can fit in any lighting fixture of your choice, so you can get very creative using them.

PAR38 lamps are the highest intensity grow light bulbs manufactured by GE Lighting, but they’re still far less intense than other LED lights mentioned here.

One PAR38 grow light lamp has a coverage area of 8″ x 8″ (20cm x 20cm), so you need more than one bulb to grow a good quantity of microgreens.

GE PAR38 grow light (with balanced spectrum) puts out even quantities of blue, green, and red light.

Those GE bulbs are very cheap (you check their prices here on Amazon), but you need a fixture to run them.

Follow the manufacturer’s recommendations to learn how to use those bulbs with your microgreens.

Final Recommendations

Growing microgreens indoor is a very rewarding activity, so don’t be reluctant to start.

But remember that it’s important to choose a suitable grow light for your plants. Don’t fall for the temptingly cheap grow lights that are found everywhere on the market. Those lights won’t work well for your microgreens.
