As an engineer, I really appreciate the scientific approach you took to answering the questions. A few notes, though. You positioned the lights above the canopy to achieve a comparable light intensity. However, due to different technology efficiencies, what we really care about is normalizing by energy consumed. For example, the CFL draws almost twice the electrical power as the Migro, so it should have been positioned SQRT(2) = 1.4 times farther away. This way, the results would reflect what would happen given an equal energy input to the different technologies. Additionally, and I'm sure you know this, your color meter really isn't adequate for determining the spectral composition of those lights. I have access to a proper spectrometer through my work, so I tested a bunch of LEDs and CFL tubes out of curiosity. The first thing to note is that expensive "broad spectrum" white LED grow lights are absolutely 100% no different than regular white LEDs. Except for rare scientific specialty LEDs, all white LEDs use a ~460 nm blue base LED along with a fairly typical mix of phosphors. The color temperature is adjusted by changing the amount of phosphor used, and thus the ratio of blue to red/green light. This produces a very sharp narrow spike at 460 nm (blue), and a broad hump from 500 to 600 nm (green to orange). White LEDs don't produce much long wavelength red light (> 650 nm). I have yet to test it, however, given your results here, I believe the best combination will be "cool" white LEDs plus some amount of typical 650 nm red LEDs. This combination will produce Large amounts of blue for vegetative growth, an independently controllable amount of red, for flowering and chlorophyll production, as well as a small to medium amount of mid wavelength greens and oranges. The broad spectrum CFLs tested did produce fairly well balanced light spectra, however the inefficiencies of CFL make me recommended never using them over LEDs.

[@extendedp1]

Thanks for the post. It would be interesting to see the results of your tests.

[@ZT_Performance]

Very interesting, thanks for the info

[@zn4rf]

out of curiosity could you try/measure the Horticulture LED Lighting from wurth electronics (Würth Elektronik Group) ?

[@prlreviews1729]

I know I'm late but this was a great reply. However, the guy did ensure all plants received equal PAR values of light, which is the amount of photosynthetically active radiation is reaching the plants. This value in turn, is the most valuable factor for this test and it is dependent on wattage and light source, so an LED that uses 50 Watts of light will not have the same PAR value as a CFL that uses the same wattage.

[@GrowingAnswers]

As a person who’s done the same experiment, I can say I’ve found the same results. Well done! and there is even more to “lack of green light” when it comes to taller plants. Soon I’ll be doing a grow experiment mixing some white light with red/blue vs all white to see if it can compare. love these tests! Keep it up.

[@vegasstacker3857]

Doesn't all white already have red/blue?

[@thelightworkersgrowseries9269]

Desert Monk depends on phosphorus used cri kelvin brand of whites,topbin or basement binned epileds or similar, and such but basicly your right but a 3500k does not have enough 660nm and close to no farred.a 3000k has a little more but then less blue and so on with 4000-6500k lesser and lesser red. So dont get me wrong MIGRO 100 And other models have great spectrum and efficiency for a 3500k. Higher cri means more perfect looking white specs as 90cri-95cri but it also has less lumen and par pr watt in most cases. 70-80cri has broader spec of colours and therefore higher lumen and par cause of 490-580nm ish peaks. I love my migro but i also wish it had cree xpe he 662nm best efficiency deepred on the market and same with their quite new horticultural specific made farred/nir/ir 720-740nm.

[@thelightworkersgrowseries9269]

Random Ryan hope u choose cree xpg3 royal blue topbin 81% wpe best on market and up to 2000mA capable but off course less efficient the higher mA used. and as mentioned on here the xpe he 662nm peak topbin c01 not b01 and the farred xpe 1000mA max. Those are by FAR the most efficient and horticulture made leds available in deepred and royal blue anf farred. Peace

[@bvolt70]

Some - but if you look at the spectral chart of a white light diode at say - 5000K, the wave will have one peak in the 450nm range (blue) but the red peak might be below 600nm. However, an LED rated at 2700 or 3000K (esp if CRI is 90 or above), will have a huge amount of 630nm+ to induce VIGOROUS flowering.

[@trollop4866]

How did your first grow turn out?

[@a.grayman6349]

This is essentially taking a modern product and comparing it to five and then fifteen year old technology. Plurple lights absolutely do work but they are old and inefficient tech. They also make it notoriously difficult to see issues with your plants until the problem has reached a critical state. It amazes me that manufacturers still get away with charging premium prices for old inefficient tech when modern efficient full spectrum lighting can be had for the same money. Once again a great honest comparison that you are known for, thanks.

[@upinyawife]

who do you think is the best led?

[@ephedrineandcaffeine]

UPINYA Quantum board or COB led. Timbergrowlights have some awesome options for noobs but there’s a lot of different brands and diy solutions out there. Just do some research on growing forums on the differences and best brands.

[@alienchannel2889]

why purple are old and inefficient if they do the work???more cost?they need more energy?

[@twentytwo138]

@@alienchannel2889 They are weak lights, and you need some white & yellow light as well to recreate a sunlike spectrum more accurately. Also, most of these blurple lights that have a veg&bloom switch, they split the wattage into 2. So if you have a 100w blurple light and you use just the bloom switch, you use only 50w. Also, most of them have fans which take some wattage as well.

[@Shadawg666]

Great video + subliminal message that these lights aren't just good for geraniums and lettuce :) I'm buying one.

[@dennismac1424]

I have been using regular household LED bulbs for a couple years in a mix of 3500, 5000 and 6500k, with about 20 watt power draw per cubic foot of grow space with about 1600 lumens per sq foot about 6-15 inches above the plants. and have good results for starting seedlings, and for plants like lettuce, basil, green onions, cilantro, and even radishes. Fixtures, wiring, and bulbs cost a total of about $5 per sq foot of coverage. This year, I'm going to try to grow to fruiting stage both peppers and tomatoes and determine the cost when growing taller plants in more cubic feet. I am setting up a (dimmable) 260 watt power draw rack of LED tubes making about 30,000 lumens maximum with 4 foot tubes and hope to get about 18 square feet of 4-5 foot tall tomatoes and peppers. Cost is about $90 and I expect pretty good results. I will start at about 1/3 power and increase as the plants grow and I have to raise the lights. . For me, it is cost- I can supply double the wattage drawn with bulbs and fixtures at less than 1/2 the cost compared to quality dedicated 'grow' lights. It would take many years of use to end up with the cost of using the extra electricity to make up for the extra cost of any decent grow fixture on the market. If I provide more wattage or lumens, it seems like the plants will end up with enough light in the spectrums they need cheaper even if I end up with more of what they don't need. When you have a product that consumers can ADD to the regular lights they can buy anywhere to illuminate their homes, you will have a product that millions could buy. If you made a LED bulb that just filled the shortfall that 'regular' bulbs don't supply, you would have hit. Consumers don't need an expensive product to produce the same light a cheap shoplight produces. All we need is a light the produces what the cheap lights don't already produce. If I can use two double lamp 4 foot led fixtures from Walmart for $16 each, or even less on Amazon,and one 4 foot tube single lamp in between them to supply what the cheap lamps don't provide, , or to balance out the % of blue/red, I would pay for it. .

[@Jackalyte]

Chlorophyll A and B don't absorb green wavelengths (that's why plant matter REFLECTS green). BUT, secondary pigments like carotenoids DO absorb green, and pass the energy to the chlorophyll for photosynthesis. It's really cool to see that represented here in the grow tests! (It also means that eye watering purple light isn't necessary for intense growth, woohoo!)

[@MIGROLIGHT]

Watch our recent video with Dr Bruce Bugbee on our channel. We cover light spectrum and the benefits of green light.

[@BState]

It's all about scattered (photons traveling to many directions) and unscattered (photons traveling to mostly one direction) light. The less scattered it is (hard light that gives hard/crisp shadows), the better/denser the growth, even with much lower wattage. CFL's light is completely scattered, you can understand that by the soft/blurred shadows it makes.

[@mgtow941]

It's hard to test it this way Make sure the plants and flowers are all sisters not all seeds are evenly strong Sorry for my bad english

[@Mr91495osh]

I use white LED Spots AND colored LED Spots at 10 inch distance AND several CFLs at four inch distance both in Ceiling AND Horizontal reflectors. Insignificant power consumption. I also use Fox Farm potting soil. Wishing I didn’t water so much. Watering is my nemesis. I have found CFL’s to as good as LEDs but need to be very close. They don’t produce heat so being close doesn’t hurt the plants.

[@LanceThumping]

I don't think the lack of green light in the RB LED is necessarily the cause of the slightly lower yield. It could be the decreased Blue or maybe the increased IR. Considering how large the change in Green was between the Migro and RB LED, I feel like there should've been a larger proportional change between the plants.

[@yungsuzzi4016]

MIGROS - SWISS PPL WILL KNOW

[@herrmoreira]

I feel ya

[@TheMotaVader]

Which one sells beer, Migros or Coop?

[@karaool]

The CFL had the same ratio of R to G as the Microgro LED, and the results in yield for the added green vs no green are minimal at best. So, to ascribe such a pivotal role to green light in your results doesn't seem justified. Seems some other factors that you may have overlooked may be more far more critical.

[@MersyyLife]

Like the CFL being mil÷s away from the canopy compared to the LEDs which were at the heights they were supposed to be. Light fades over distance, the LEDs are focused to correct this, the CFL could probably be 100mm away from the plants and not damage them allowing light intensity equivalent to the LEDs

[@dragongaming4993]
