Full Spectrum & Light Wavelength Explained
Absorption of Light
Just like how we can see only a certain range of light spectrum with our eyes, plants use a certain range of light spectrum to grow.
When cannabis grows outdoors, the sun provides the full spectrum of light that the plant needs to grow naturally. Sunlight gets absorbed by the plant’s pigment molecules for photosynthesis (plant growth).
LED grow lights are designed to provide the optimum light wavelengths most beneficial to plant growth. We call this optimal range PAR, short for photosynthetically active radiation. The PAR spectrum includes the light wavelengths of approximately 400nm to 720nm, illustrated below:
By looking at the PAR spectrum graph, we can see that plants use some colors more than others. A plant uses blue light (400nm–500nm) and red light (620nm–700nm) wavelengths in the greatest concentrations. This is why we measure the performance of LED grow lights in relation to PAR output rather than Lumens.
You can check the PAR output of a grow light using a PAR meter (also called a PPF meter). This handy device measures per second how many photons of light hit the sensor.
- PPF, short for Photosynthetic Photon Flux, is the number of light photons that make contact with your plants every second. Only light in the ranges of 400nm to 700nm is measured. The unit of measurement is µmol/s.
- PPFD stands for Photosynthetic Photon Flux Density. PPFD, measured per second and square meter (µmol/(m-2 m-1 simply written as µmol/m²/s) which we call micromoles or “uMoles” as slang. PPFD shows the density of PAR light in a given area, such as the density of PAR light at 12″ away from the LED grow light. We use PPFD to measure the PAR output of LED grow lights.
Testing the PAR output of a LED grow light may give you an idea of how far away to hang your lights from the plant canopy for optimum growth.
- 600–1000 µmol/m²/s: High strength light, the best range for developing growth and flowering.
- 400–600 µmol/m²/s: Medium strength light, for early veg and stretching.
- 200–400 µmol/m²/s: Low strength light, good for delicate seedlings and clones.
Red Light vs. Blue Light
When designing full spectrum LED panels, manufacturers dial in on the color wavelengths that plants absorb the most of while also providing other colors for balanced light exposure. Most importantly, red light and blue light.
A balanced full spectrum LED grow light will have not just one red and one blue color frequency but a whole range of light available to plants. This provides plants will get a similar spectrum of light that they would expect from the sun.
Red light in nature helps to promote all-around growth and the flowering process. In nature, red light comes out from the sun during late summer and fall, which can explain part of the reason buds form up fat then (the other part is light hours). Red-heavy grow lights do promote heavy budding and flowering, but this doesn’t mean that you should only use red light for your plants.
Balanced with blue light, red light can be used during the whole course of a plant’s life—from seed to harvest. Plants need red color light need to grow healthy. Interestingly enough, plants make the most amount of energy during photosynthesis from red light.
Don’t be fooled by the color you see—even MH (metal halide) grow lights that don’t look very red provide a fair amount of red light to plants. Many LED grow lights also are red-heavy.
Although plants can be grown with pure red light, too much of only red light will not help early vegetative growth. Blue light is also required in good quantity for happy plants!
Blue light is so important that plants literally don’t know where to aim their leaves for light absorption without it.
Plants thrive in their early stages with sufficient levels of blue spectrum light. In the outdoors, blue light is most present during the spring and long-day summer, as plants are in a similar “vegetative” process of growth, naturally.
Without blue light, vegetating plants seem to stay small and stunted, resulting in short stems and squat stature. Many LED grow light users even add blue light-heavy fluorescent lights into the grow room during the plants’ early stages to get an extra boost of blue light.
If you want tall and leafy plants, crank up the volume of blue light, and you’ll get just that. Certain LED grow lights are designed with adjustable blue light and red light dials.
However, you probably just want to run them full blast red and blue for the whole growth cycle, unless you have specific plant size and grow space goals. Too much blue light during flowering will result in stretchier buds, so if you see that be sure to cut some blue and pump up more red light.
Ultraviolet (UV) Light
Ultraviolet (UV) light under 400nm consist of three main rays:
- UVA (315–400nm)
- UVB (280–315nm)
- UVC (180–280nm)
The newest LED grow lights usually have a few bulbs in the UV range for a few reasons.
In nature, plants are exposed to the sun and are naturally exposed to the ultraviolet radiation that sunlight contains. When humans absorb UV radiation, we produce melanin to defend against the sun’s rays.
Cannabis, on the other hand, produces trichomes filled with cannabinoids, including the favored Δ 9THC and CBD to protect the plant from UV radiation. In essence, UV can be used to stimulate THC production.
Outdoors, the sunlight at higher elevations gives plants more UV exposure. The growers who live up in the mountains swear their stuff is more potent due to the increased UV exposure, which makes the plant produce more cannabinoids.
In Hawaii, we’ve noticed the weed in high-elevations gets super frosty and stony, although it doesn’t yield as much as the low-elevation buds. More anecdotal evidence can be found in this hashish book written in 1965 about the finest quality hash being obtained from plants at high altitudes.
This is why many growers swear that it’s beneficial to use a little UV light—for increasing the plant’s production of THC. You tend to see the best LED grow lights have UV bulbs added standard.
However, be aware that UV radiation overexposure has been known to degrade different plant processes, including damage to DNA and damage to physiological processes. Too much UV radiation has been shown to induce plant mutations. And is harmful to humans.
Outdoor growers don’t need to worry about UV overexposure. The only real danger of UV radiation to plants is from using artificial germicidal lamps to provide short wavelength (UVC) radiation to plants. In other words, you can burn up the plants with too much artificial UV light.
Most of the best LED grow lights on this list feature a small number of LEDs in the UV spectrum, at a safe level for plants and humans.
Infrared (IR) Light
Infrared (IR) and near-infrared light consist of wavelengths over 700nm. Invisible to the human eye, infrared light is felt as heat.
PAR would tell us that deep red (short-wavelength, 680nm), far red (>680nm) infrared would be at large unused by plants for photosynthesis. Only one photoreceptor, phytochrome, is known to respond to far red wavelengths. Phytochrome helps plants regulate photo-sensitive changes, such as when to start the blooming process.
As we learned from the Emerson Effect, Robert Emerson’s research showed that plants simultaneously given these wavelengths grew at a much higher rate than the sum of the red light and far red light alone.
This gave reason to believe that plants may have two photosystems—one for utilizing short-wavelength light and another for using long-wavelength light.
Infrared LEDs can be found in a lot of the LED grow lights above. The Electric Sky 300 has gained a massive following among cannabis growers for integrating these red “wideband” wavelengths into their lights.
Advantages of LED Grow Lights
There are many benefits to using LED Grow lights in your indoor grow room or even in a protected outdoor environment like a greenhouse.
Simplicity is Cool
LED grow lights run cooler than MH/HPS HID grow lights, and the bulbs last much longer.
Compared to an HID indoor grow setup that requires a lot of electricity, cooling, and ventilation efforts, LED grow lights can be set up effortlessly in a closet, grow tent, or similar space without renovating it completely.
The beauty of LED grow light technology is that they are as easy as plug & play for most situations. The fans and/or built-in heat sink will keep the grow light at a comfortable operating temperature.
This means that you do not need to spend the money or effort into building a super deluxe indoor grow room in order to grow a healthy cannabis crop. Just buy a grow light, crack some seeds and get growing.
Low Wattage + High Efficiency
As opposed to HPS and MH lights, LED grow lights run at a much lower wattage while producing more PAR light-per-watt for plants to absorb and grow with.
This high efficiency and low power draw opens up the door for alternative energy sources, such as solar-powered grows. For a few hundred bucks, you can buy a solar panel, deep cycle marine batteries, and an inverter to make your own solar-powered indoor grow room. To do it the cheapest way, you can just run the light during the nighttime and move plants outside to grow with the sun during the day.
A big step up from fluorescent lights, LED lights have enough penetration to stack even the inside of cannabis plants dense with fat nuggets. Whether they’re in vegetative or flowering cycle, LED lights can do the whole job well done. The “blurple”, pink, or white glow emanated from these grow lights is strong and bright enough to give you a dizzy feeling. Remember to wear eye protection when operating LED grow lights.
Modern LED grow lights of today surpass the earlier models of years ago in the available spectrum, durability, and light strength.
Yields for indoor growers finishing cannabis under full-spectrum LED lighting average ½ gram per watt among growers in the United States. This is considering the true power draw watt, not the rated equivalent advertised.
The ballpark ½ gram per watt figure takes into account that your grow room will follow the proper space guidelines of the grow light and that the plants will be optimized for growth, e.g., soil, water, nutrients, and care.
Of course, yields vary from strain to strain. That’s part of what makes growing new strains so fun. Check out these top-ranked best sativa and top-ranked best indica strains for some good cannabis strains to grow under LEDs.

Hii!! What choose Mars Hydro TSW2000/TSL2000 or Spider Farmer SF 2000?
Did side by side the laddies don’t care at all what brand chips or drivers save your money Mars is best for the buck
Quality? Im a tsw2000 owner and I’m also interested to know why marshydro not spiderfarmer?
I ordered a 1600 watt marshydro II from walmart.com and it ended up being out of stock so they sent me TWO 900 watt MarsHydro II and I have very expensive blackdog’s & Cali Solar system… My mars hydro 900 watt is ten times cheaper then some of my other lights and have had results just as good!!! Don’t drop obscene amounts of money on a LED light until you do your research and know what your getting! I’ve seen first hand…
I’m a new grower and need help finding a solid led could you please help I’ve been on hundreds of sites and just can’t decide
Hi,I recommend this light!
I run Electric Sky 300s and wow the wideband spectrum is amazing, it grows the plants bigger, leaves, stems, size, everything, but I still get tight internodal spacing it works wonders and I’ve grown with those other white LEDs before and they just missing something don’t sleep on the ES300s
I’m surprised Optics LED growlights didn’t get mentioned in this list despite using the latest in Samsung LEDs and uses Meanwell drivers.
Wow! My Google search found everything too do with growing pot..!
I want to start a plant from a cutting and maybe, get some cukes and tomatoes started next spring..
..Building a chamber for germination.. The floor will be about 2′ x 2′. RH and temp will be controlled…
What distance and LUMIN output shoud the LEDs have at what distance…?
VOLT Grow is a newer brand, but should definitely be considered when buying LED grow lights in 2021. The FL-1 Full-Cycle LED grow light has the highest light output in the market at 2000 µmol/s with a 2.8 efficacy (720W). It is $1,049, which includes a dimming control, mounting harness and power cord, and has a 5-year warranty. They use Samsung and Osram chips and all products are UL and DLC listed. They also offer the VL-1 Full-Cycle LED grow light, which is a smaller, cheaper product.
Ive been running withe the iL8x from Iluminar and honestly I think it should be on this list. It provides high quality yields and hasn’t given me any problems in almost the year that Ive had it
The information about Mars Hydro SP3000 is wrong it’s Samsung LM301B + OSRAM660 not Epistar 🙂
