Full spectrum grow light comparison test – COB vs Red Blue LED vs CFL

hi and welcome back to the Migro YouTube
channel my name is Shane and I’m the founder of Migro in this video we’re going
to look at the effects of different full-spectrum grow lights on plant
growth and yield we’ve set up an experiment or we are going to show you a
time-lapse grow over the last six weeks of a selection of bedding plants and
lettuce which we put in each of the bays here we’ve got three different types of
full-spectrum grow light we start off with the 100 and my goal 100 which is
drawing 106 watts it’s a full spectrum LED cob that’s been raised quite high
because of the were keeping the intensity of the lights the same in each
of the bays in next Bay we have blue red LED panel type LED in this case it’s a
UFO and it’s drawing about 165 watts and in the last Bay then we have a dual
spectrum CFL which is 250 watt electrics model with reflector which is drawing
200 watts so we’ve set up each of the bays with the same plants underneath the
same pbft or power level and across the top of the canopy and in each of the
bays and we’ve run the experiment for six weeks we’re going to look now to see
what the the health of the growth is like what characteristics the growth has
and what the yield is in the end so all of the lights have been set up to give
the same power level across the same collection of plants under the same
conditions the difference in terms of the results from the growth is going to
be determined then by the grow light spectrum we have tested each
of the grow light spectrum using our sensotec passport it’s a spectral
radiometer and from these readings were able to show you the proportion of the
different spectrum of light in each of the grow lights we can show you here the
table using the Sun as a reference these grow lights are sold as full spectrum
lights which means they should be replicating the light of the Sun as
close as possible the infrared is effectively heat and doesn’t contribute
to light grow to Planck wrote and neither does UV so we can not look at
those for the moment we’re just looking at the proportions of blue green and red
blue is known to control plant growth specifically the lengths of stems and
therefore affects how stretched or how dense the plants are under the grow
light spectrum we have shown previously and it’s it’s scientifically proven that
blue light between about 15 and 20 percent is optimum 15 between 15 and 20
percent you get short dense growth so there’s enough blue there to control and
keep the plant growth dense but not too much because to more than say 20 percent
of blue light is going to reduce the productivity next we have green green is
is proven to be almost as efficient as red in terms of photosynthesis about 95
percent is efficient the big benefit is that it means system through the the
plant canopy and gives you really good penetration down into your grow getting
lots of flower and bud development down into the plant next is the red the most
highly efficient to the photosynthetically and so we’re go to
see for these mixes which performs the best in our grow test here so that’s
look as a results we’ve taken the plants now at the growth
chambers to have a look to see how they did over the six-week test starting on
the micro side it’s looking at the bedding flowers good healthy growth lots
of nice sized flowers right across the violas and the pansies looking at the
lettuce then you’ll see the growth is nice and dense the main head here it’s
good and pick it very dense got a growth there in the center and the smaller
heads are nice and dense – looking down underneath the UFO very good flower
development about two violas and the pansies the growth and the lettuce is a
little bit more stretched with very good weight and dance feet on the main head a
little lighter and fluffier on the younger heads then under the jewel
spectrum CFL we’ve got a pretty good player development very good for around
actually on the viola but here on the pansies unfortunately got a bit of
disease and infestation just the last few days but they were looking nice and
healthy up to that point so no concerns they’re looking at the lettuce you can
see it’s a much higher growth more stretching much less dense a lot lighter
the Maine has quite scraggly and lice the
smaller heads as well so overall good good development and all the plants the
UFOs probably got the best in the flowering response and with my grow
second and the CFL turd it’s not the lettuce I’m looking at the health of the
growth oh my go has the shortest answer scrote with the what looks like the
biggest mass with the UFO second in the cfl third let’s get to the let’s harvest
the lettuce and see what weights we get we can see all the results now for the
grow test on the left hand side we got the my grow at 106 watts with good
flowering dense growth and highest year the 380 in grams the UFO draws 165 watts
good flowering dense growth and the second best yield of 272 grams the
electrics Jill spectrum CFL badge stirs 250 watt but draws 200 watts I had good
flowering but unfortunately the growth was light and stretched unit developed
to a low yield of only 130 grams so seeing all the results from the
comparison grow you can see that the red blue and LED from UFO along with the
carb spectrum from my grow boat deliver strong healthy growth it’s often said
that the green portion of grow light spectrum is not product
and doesn’t photosynthesize and deliver yield you can see from the test that the
green portion are the mixture of green into the spectrum and the Cobb LEDs
actually delivers a slightly higher yield for the same power levels across
the grow area however the blue and red LED the UFO did deliver slightly better
flowering so there was slightly more petals and slightly larger size the CFL
growth was very disappointing the the electrics Joule spectrum CFL was badged
as a 250 watt but only true 200 Watts and then delivered a stretched and low
yield it’s likely that even though the power levels measured across the grow
were the same and the light was was long as low as possible to the plants that it
was spreading the light a bit of ran the plants and not getting directly onto the
grow so probably suffered a little bit that way but as I seen in in other grow
tests the relative yield from a CFL is much lower than then from LED so hope
you’ve enjoyed if you have please subscribe
take care

  1. we know already! ! . just give the results dude. ! …. after a few more minute s . . C YA . . bye . ? m. ? dumb.

  2. GOOD JOB.


  3. conclusion grow outside fullspectrum sun natural light also greenhouse never use fake light its sub standard unless you live in arctic but thats just fucking stupid!!! Live in Cali to equator and get three to four crops a year naturally AMEN

  4. See one @t  he have the new generation of led grow with Japan technologie, the name of light fixture is AIR GROW 800 he make more of 2 000 PPFD, see on instagram futur-of-grow​  this products is use by the winner of the cannabis cup 2018 https://www.sciolaimport.com/shop/AIR-GROW-PRO-800-p124558356

  5. No shit it’s a cob vs a led ufo not fair comparison vid your jus promoting your product of coarse it’s gonna win every time lol

  6. Why don`t you put full spectrum higher, sir? It would be much more intresting demo if full spectrum also light from other room trough the wall. Thanks!

  7. How would the yield differ if you used a combo of 2 of the 3 lights. Would there be a difference?

  8. You my friend are a legend. i love the information you share, really helps a first time grower such as myself. Kudos mate.

  9. Too many variables to be a true experiment. Great Idea – Bad Follow-through.
    Must control environment first. Do experiment in a clean grow room environment not some workbench in a back office. Use sterile grow medium and common fertilizer and feeding schedule. Infection in CFL plants highlight this issue.
    Should have started with identical clones in common hydro setup to measure different growth potentials of different light spectrums. Light spectrum must be the only variable for the experiment to answer more questions than it raises. At least they did their best at equaling out the power of light used on each bed.

  10. 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.

  11. Little question, I have 6 CFL 100w, 1600 lum. each on a 3 foot shade, 8 inches apart, I just got my red blue led 30 Watts ( 100w. equ.) at 1300 lum. I was thinking putting all together but don't really know if it will be helping my plants, so 6 CFL at 8-10 inches apart and between my red blue led, if somebody know please would be appreciated, thanks.

  12. i would like to ask a quation .

    100 migro effects howmany m2 ? how long away we can hang ?

  13. Even though your advertising your own product. The way you done a proper comparison between the 3 lights. Is awesome as you proved that cob is better. Keep up the good work mate😎

  14. 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.

  15. LED will continue to take more market share because of its durability, reliability, thermal control, and energy efficiency. No other light will be as cost effective in the longterm. You may pay more for LED up front, but you won't have to replace it as often or drop your jaw at the electricity bill.

  16. I just have 3 questions:
    1: How is it a side by side comparison if you're not using the same wattage for each test?
    2: Does anyone know the best way to roll the lettuce leaves. Do you dry and grind them or roll then like a cigar?
    3: Which variety of lettuce do I grow to get the biggest hit?

  17. IT would be interesting to do a 4th test with all 3 lights on one set of plants and determine the growth and yield.
    The hard part of farming, we humans only have so many years to live, so only so many crops and seasons we can harvest. 🙂
    Time, the rarest and most precious, and often wasted greatest Gift.
    This Diagram Demonstrates Using Full Spectrum Lights from above, and Red-Blue Purple lights along the sides wall mounted:
    Place your lights on two circuits : So when you are working in your green house, turn off the Purple lights (they are annoying to look at), but leave the day light on to see what you are doing.

  18. 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.

  19. What can a 9 watt Red and Blue L.ED grow ?? I have one in a lizard tank above some plants that seem to not be doing to well .. How high from plants should I keep it ?

  20. Please Test the "CF Grow" LED Light from Amazon 200w CXB3590 x2 . Ich think its fine. Good components :Cree cxb3590 / meanwell Driver / Weco connectors /ideal holders and 90 ° Lens.

  21. ok dude we all know your high as fuck lol youve probally never even grown those flowers before. lol we all know what kind of flowers you be growing CX

  22. My reaction when watching the time-lapse: "shit….. holy fuck… there's a big fuckin' difference… shit…"

  23. Non-driver COB SPECTRUM GROW light https://loktatech.es.aliexpress.com/store/4288045

  24. I'm looking for a new led grow light that puts out some heat but doesn't get my box up to 100°f and I would like to get away from the purple light.
    Also I don't want to sacrifice things for less power consumption. But my 500 watt led is too much power

  25. You should run the same experience with cloned marijuana plants.. please? I’m asking for a friend..😉

  26. I think the CFL was slower but better , the lettuce could have went a little longer, probably wasnt done,yet

  27. This guy is high as fuck. What lights does HE use at home?! I want THOSE lights!!

  28. Hey Shane can you please review the happily lead light? Www.happyleaf.com

  29. 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.

  30. Please do a research video about aquarium mosses.

    Particularly riccardia moss that is the slowest growing one and you will be drawing all aquatic plant people as your subscribers too🙏🏻

  31. https://hightimes.com/grow/grow-hack-how-to-use-a-uv-lamp-to-increase-thc/

  32. Jesus, how can anyone buy a grow light with these prices? Assemble your own and save 200 dollars per light DX.

  33. fool that spends too much for a grow lights or ect, to any big grows in the USA 6 year supply in some state PRICES WILL GO DOWN A LOT

  34. i though plants cant process green light?? that's why we use it in cannabis gardens at night is it not?

  35. Please compare the nutritional values of those tests, is there a Peer-Review of the test specifics ?

  36. And this is why we love our eggheads, because of their smart & scientific approach! Many thanks for all the great info.

  37. Sampling size of 1 plant will not be a scientific probability point of view. They should run more replicates per treatment and a statistical analysis be done on the data to make sure that the conclusion made have a more realistic probability.

  38. How many plants can be grown in Full Spectrum LED for indoor/outdoor RED(630-660nm) BLUE(440-460nm)?? 50V??

  39. Jesus noel gallagher.. drink a glass of water before d next video.. d noises flapin out of that mouth are turning my stomach

  40. How high above your plant is the led UFO? Thanks, im trying to find the sweet spot for a 100 watt full spectrum led.

  41. What if you were to mix both lights a full spectrum and a red/blue. Would they somehow block each other out

  42. All of those lettuce look as sick as fuck. They're way too packed in.

  43. Your marketing your lights bro let's get real. Your light was much higher which allowed the heat to dissipate much more thus allowing a better yield. Then at the end you lowered YOUR light when comparing them which was NOT the way the test was conducted. Fake test

  44. whats so special about the COB 100w (cree3590)? it gives off 12,000 lumens same as HPS or i mean if you ran 1000w hps = 120,000lumen.

  45. I'd love to see a video on the blue spectrum red spectrum and duel spectrum CFL?
