The white LED brand is Roleadro. It is 115 watts at the wall. The Blurple light is 130 watts at the wall and is generic brand. Info for these lights can be found in the links below.
I used the nutrient trio from General Hydroponics. I started off with a seedling dose and then jumped to the aggressive vegetative dose after the plants had their first few sets of true leaves. I started the test off with 6 gallons of water in the container and ended with a little over 3 gallons. The entire grow was over a period of almost exactly 1 month in a consistent ambient temperature of 68F.
The PAR output was kept under 300um of light at the plant canopy with a short period of slightly over 400um in the highest spots, but was adjusted quickly. This is when the minor tip burn occurred. The PAR output on the lights was almost identical and the center PAR measurements are 1000um/6" - 400um/12" - 200um/18" on both lights. The type of lettuce was "Black Seeded Simpson" from Burpee.
The time lapse camera used was a Brinno TLC 200 Pro with the kit lens. 1 photo every ten minutes. The night cycle was removed in post and the remaining clips were sped up in post by roughly 200%. If you look closely you can see most of the growth actually happens at night. The lighting hours were 17 on.

Considering you grew lettuce which does NOT flower or produce fruit... its perfectly logical that it DOESNT need red light which is important for flowering and "fruiting"and not vegetation and most full spectrum leds have 60-70% of red led diodes... Just saying.. You should do some fruit grow actually ... If you did send a link
SRB NS to say that lettuce doesn’t need red light is false. All plants need red light. The ratio is what matters. th-cam.com/video/pgpjACVfLvA/w-d-xo.html
Growing Answers yeah needs little red but most blue
Actually lettuce absolutely flowers, you just want to harvest it before that :)
All leaves contain two types of chlorophyll, alpha and beta. One is activated by red light, the other by blue light. But there other biochemical roles for light. For example, plant can react to green light, avoiding that area, probably due to competition with other vegetation. Seeds respond to infrared.
Both chlorophyll A and B has peaks in both blue and red.
This video was about a million times more helpful than Google search was in finding a clear answer
you're still on Google
google is a chinese style censorship on everything.
@@AJ-rs3ub "google search"
And yeah, youtube is always better for complicated answers that dont need a simple yes or no
I would have to agree with you Franklin
"I swear im just growing lettuce"
The weed just appeared out of nowhere
The devil's lettuce!😉
Hehehe 😁
Hey, I wouldn't mind growing a female pot plant and besides where I live its legal now.
@@rscott2247 Technically, it's not legal anywhere in the United States because it's still banned at the federal level. States do not have the authority to override a federal prohibition. So, when a state legalizes, what's really happening is that the state is saying they won't pursue it at the state level, but federal authorities still can and often do act even in those states.
In Illinois, for example, it's been made legal but a guy across the street was operating a drug house and the police did this huge operation to shut him down, remove him, and board up his house. They had an actual tank right in front of my house. Scared me as it woke me up! The thing is there were so many complaints about all the other activity related to the marijuana that they pulled some strings and had federal agents come in and had him charged under federal rules.
There are also public smoking bans in place for good reason, as many people are allergic and even those that aren't have a right to choose not to get high so public smoking bans are in place to make sure everyone can use the public place. Since ingestion is preferred for medicinal cases anyway the authorities do arrest people who violate public smoking bans regardless of what they are smoking.
Additionally, any federally funded program has to follow federal rules, so college parking lots, federal highways, federal parks, etc.

Answers about lights that should be tossed in the garbage. Far inferior to soft whites or florescent.
you just solved my 1 year problem in 4min, really appreciated
There’s also the added benefit of enjoying your beautiful green plants under normal light rather than feeling like you’re stepping into a darkroom every time!
I personally love the dark room feeling. Just sayin
You eat in your darkroom?😅
Two years later and this video was a million times more helpful than other videos and google searches thank you!
I can't wait for part 2 this is an exciting video, thanks to your experiments I've been able to optimize my grow system , thanks for all your hard work Ryan!
The reason why you got bitter taste of the R&B light is that under such condotions leafy vegetables tend to synthesize isotiocyanates in a higher degree. The enzyme called myrosinase which synthesizes isotiocyanets from glucosinolates is in that case not inhibited by the natural light and if there is predomenance of red and blue light. Overall thanks for the cool video!
toi tu n'étais au fond de la classe a côté du radiateur!!ou alors tu es copain avec narcisse!!humour de bas étages désolé!
Hahaha thanks! Excellent.
So is it a good thing to have the isotiocynate more?
@@osirusj275 if you want your lettuce to taste bitter then it would be good but for most people that is not good.
How about plants that you're not planning on eating? Is it a good thing?
The red/blue lamps should be considered multi-spectrum and not full spectrum. White lamps are actually full spectrum. It would be interesting to see a comparison with fruiting/flowering plants and non fruiting/flowering plants under 2700K, 4000K, and 5000K LED lamps and compare the results. Nice hands on experiment, thanks.
I appreciate your concise but fact packed video! I've been experimenting with different lights for starting seedlings lately and your findings have been really helpful. Will be sure to check out more. Cheers!
You set my mind at ease regarding my choice of already purchased white lights. This was great thanks a bunch! 🤗🇨🇦
Brevity is the soul of wit. Great work. Thank you
Thank you sooooo much for this video. I am studying grow lights, in order to get a head start on my summer plants.
Thank you Ryan i been looking for really good information on Purple vs White lights Thank you soo much
I watched a ton of videos trying to find the answers that you so easily summed up.
Thanks
That video with absolutely brilliant! perfect length and full of information! 10 out of 10
There was more red light in the "white light" LED panel, which caused the leaf to become larger... however, despite the size of the leat, the nutrients/phytochemicals produced in the leaves are pretty constant, so the "bitter" taste in the predominantly blue light was due to these flavors being concentrated into less biomass, but equally healthy leaf as the white-grown, which actually had more red light.
The leaf morphology (size) was affected by the spectrum. The amounts of phytochemicals responsible for taste were not, and in probably equal amounts "per leaf", but not "per gram".
Great video short and sweet and answered exactly what I wanted to know, would love to see the same test on a flowing plant in the bloom stage to see if the results differ
th-cam.com/video/v0sDHZYjdKk/w-d-xo.html
I am so glad I saw this before unpacking my new red & blue lights!
I wish I found your channel a few weeks ago (bought some lights in a rush. Would have made different choices had I known what I'm learning from you). Love the channel, keep it up!
Really like this video. Great shots, contains all the info I hoped for and it's still compact. Pleasantly professional.
Would b great to see a test run with both types of lights in the grow!
Cool, awesome experiment. Now i know which light i choose for my aquaponic.
Thanks for your video and keeping it short and to the point. Will keep watching your channel
Really great video. Short, snappy and to the point.
Wondering if you managed to do a cost analysis of electricity, seeds and potting compost per plant vs store bought lettuce.
This guy was not looking for answers to his questions but was giving only facts that presented.
Excellent presentation.
A+++++
Thanks for really shining a light on this topic.
OMG excellent time lapse show of comparison of various led lights!! Awsome hydroponics set up wow. Simply amazing grow op for your leaf lettuce. I must pass this on to my brother. Thanks for posting and sharing. Sharing is caring!!
It's kinda scary to watch lettuce growing in timelapse...
you have a weird reaction. I like its way of growing.
I like it. It looks kinda cute. Happy growing plants!
It's not scary!
You ain't seen much scary then son !
It seems fleshy and alive
Thank you for this test. I bought white light leds only because I don’t like working under colored light. It’s nice to know I haven’t had to sacrifice quality. LIKED 👍
Was it ever validated if the color LED produced more nutrient plants? This was at 2:30
Thanx! I’m a neophyte trudging my way through the jungle of reviews and suggestions! My head is spinning! What I want is a good, not expensive lighting system to wintry my plants and start growing peppers from seeds!
This is what I was looking for. You are crystal clear boss. Thanks a ton
Great video man keep it up !!!
Thanks for growing answers!!! Nice to know someone of intelligence is doing some worth while research using these new types of artificial lighting. Thanks and keep up the good work/research. I look forward to watching more of your videos. Ps the time laps was an awsome way to show the difference between the two types of lighting!!!
The biggest part of this experiment that I find most fascinating is the difference in task due to the lighting. I am interested in seeing the outcome of the next experiment and what plant you will be using.
Nice video. I have been wanting to try to start growing plants indoors but it is rather daunting trying to figure out how to begin. Glad for the info on the lights, both in video and comments.
Done something similar on my last grow,purely accidental.Started grow under mars hydro purple,friend gave me a white led spider farmer 5 weeks into grow.Results were beyond belief,best I ever had.This 50/50 mix seems best of all,just my take on things!
I wonder what if we give 10 hours of sunlight or white light and 5-6 hours of red blue light. can you please do a video on it.
You produce amazing videos!!! Thank you for all of them. Absolutely loved this content. So informative. Be well.
This channel has a very good potential bro. Nice contents.
Thank you! I have a new red/blue 200w(real) led and i couldnt figure out why my plants where doing so slow compared to some other 500w cfl (100w real) that i have...now i know that it will matter on the end product, after flowering.
the amount of watts drawn doesn't tell you how much brightness is there. Fluorescent can be 0.95 umol/w whereas the best LEDs are all 2.0 - 2.4 umol/w, literally twice as efficient. The problem is that generic LED can be much less efficient than 2.0 umol/w. Ideally, one should avoid LEDs with isolated bands of frequencies and just go for a broad spectrum light that's white from 3000 - 4000 kelvin.
Thank you! This helped me make a critical and educated shopping decision.
I like your time-laps. Thanks for that. Thumbs up!
You have to use clones as a control. Any plant from seed will vary in size depending on the seeds growth potential.
I wouldnt have never imaginated (sorry for bad english btw) to be in the middle of a war between led colors...please, go on! haha
OP, your video was really informative. Im trying to grow my own microgreens garden!
This was such a good video! Very insightful
amazing introspective comment at the end "I didnt grow plants, I grew answers" top broseph style gg
谢谢你的分享！我使用红蓝LED灯种植出来的生菜也是味道很苦，和你的结果是一致的
Thanks for sharing! The lettuce that I planted with the red and blue LED lights is also very bitter and is consistent with your results.
It is my understanding that 6,500k is the best color temperature for growing. I was surprised that the white light used in this video did so well considering it is at a much cooler color temperature. I would be interested to see a comparison between a 6,500K white light vs the one you used in the video.
Thanks!
Much appreciated!!
Great lapse!
Solves my problem. I need to bump up my wattage.
Thanks for this video, now I know which one to choose. I was leaning towards the red/blue before. I'm glad I waited. I'll be buying white lights for my succulents.
This is a much better video format than your older videos. It's clear you're dedicated and improving! I've noticed the same bitter taste with plants grown under blurple.
I'm putting together a 250w fixture of 150w warm white COB and 2 50w 'full spectrum' cobs from Lustreon - we'll see how she goes.
Sounds like it should work well. And thanks. Ive made videos long before TH-cam existed actually. I used to spend ridiculous amounts of time on them, but those were mostly short films. After that I did various things with video and never really stuck with one thing. The reason my older videos were poor was because I got very put off by video making and became lazy about it. I tried to edit as little as possible and also tried to make the process less complicated (on my part). My focus became just getting the information out there without any good structure. Honestly I still don't really like making videos. It used to be a hobby about 16 years ago, but after a certain point it just felt like work with no pay off. But now I get paid so it's sort of like running my own business so I treat it as such. I would still do experiments and grow stuff even if I didn't film it though.
Zachary Melo has nZSgy
Robert Theref ur right in most cases, but coating a lens with a color doesn’t make a light change color, it merely filters out the other colors and you are left with a single color. It certainly changes the ratio from one color to the other, but doesn’t add any. in other words, you don’t make a white light “more” red by adding a color filter. You’d be better off adding a red light in addition to the white light.
Robert Theref filtering the light will waste energy. The plant does the filtering through its pigments.
Nice. I would be interested to see what the 'dry mass' was of both types also. I was thinking that the white light plants may have more water content - perhaps larger or less compact cells and the bitter taste of the RGB plants may be as a result of this. Liked the experiment - well done.
Useful video buddy, congratulations!
Thank you for sharing your results.😊
The higher percentage of blue light in your RB led is the reason of higher chlorophyll compared to the RGB led ;) and blue surpresses leave extension so the leaves were less elongated than RGB because of that, despite the same amount of red.
The comparison with an Osram Phytofy RL panel programed to grow seeds then green leaves would have been great, to see if the extra cost is worth the extra production and quality.
You just need the blue spectrum LEDs for green leaves, together with full spectrum white LEDs. It's not just the one or the other, the white and the blue/red/white LEDs. It depends on the vegetation stage, if you want to simulate dawn/sunset, etc.
Now that we have both infrared and UV LEDs, I will be playing with these 2 in a very small ratio compared with the growing LEDs.
Just like direct LED lighting hurt our eyes, I think I'll try with a translucent glass between the LEDs and the plants, just like there is atmosphere refraction on Earth, it may be why you experienced burns on some (very few) leaves.
Just the info I was looking for! Thanks so much for this video :)
Good video for the topic. Also interesting for teaching beginners about scientific approach. Keep them coming.
I think it would have been important to dehydrate the plants and see their "true" weight. The non-green plant may have been more dense, and technically "larger" than the green one. Then burn the dehydrated mass to extract and weigh the various vitamins (copper, iron, potassium, etc) contained. The reason for the bad taste could have meant more nutrients were present.
He did say hobbyist. I did not see a university style laboratory in this but a nice comparison video on led lighting with lettuce.
@@lostcivility9849 do it right, or don't do it.
@@kennethkline7702 go on then kenneth, show us how its done
@@kennethkline7702 If that was any scientists actual approach nothing would ever get done. What a clown. At this scale, for this purpose, this was a fine experiment.
Just be glad he used more than one plant on each side, ya testicle.
for all the ppl that will call me incorrect the white light is actually all colors of light combined so with the colored led you are actually limiting the radiation from that spectrum Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. ... White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly-chromatic light
Im gonna be using metal halides for my system for the simple reason that when I observed saltwater aquariums equipped with metal halid lights the color of the coral was superior than that of led this is just my opinion I've tried T5's when they came out and i wasn't impressed prolly better now but doesn't matter the halides were free
So cool! I can’t wait to try this. Thanks for this 😊
Great video. I have been thinking about getting grow lights to start my veggie from seed this year. Can’t wait for part two on this. Keep up the great work

In the 1980s NASA released info on plants and the light spectrums they need. You basically gave lettuce more of all the vitamins it needed with blue 440-500nanometer spectrum light (left). Leafy greens do not need other spectrums of light.
And yet, white light clearly produced a better yield.
@@TheRanguna Yes, because it has more blue spectrum which is the only thing leafy greens use. Do you have reading problems?
@@9001greg Doesn't white and blue red have the same amount of blue ?
@@TheRanguna No...
@@9001greg Well, it probably depends on the bulb.

White is for vegetational growth
Reds and stuff are for flowering.

@@reefermadness7155 it's good cause I had the whole set up for free. I didnt spend a penny. 💗💗💗
@@albertoasia1368 nice man good growing
IMO: The red/blue color gives the lettuce enough light(just right spectrum they needed) so no need for them to grow their leaves more widely. On the other side, with the white light, the lettuce needs wider leaf to absorb more light they needed. Just like when you give them enough sunlight and not giving them enough sunlight.
Bro I have red blue grow light but I turn it off here these are my reasons
1 . Serious headache 😫
2. my eye sight loos they damaged .y eyes bad
3. Making fish really uncomfortable they just hide from light and few died.
These lights were no good for my aquarium.
Very cool experiment. Thank you
still.. the ULTIMATE vids about growth comparison in the planets.
Actually the most important would have been to have them tested to which one had more nutrient value. Visually speaking it appeared to me the white light plants looked much healthier to me.
How about mixing both lights in one grow?
Peter XYZ Better in white. 😊

@@bebehasbebehas2287 does it matter?
My experience is similar to yours.
White/yellow light 💡 is more practical and better for everyday use than LED Red/Blue lights.
Also the Red/Blue seem to burn my plants quick which is not good
Thanks for your review 👍
Very informative and succinct video! Thank you!
wow! short, sweet and to the point!
Of course I found this after I bought a red blue light for my greens. As a novice I'm slightly discouraged. 😔
Melanie Stewart Dont be!!
Thats not an entirely fair comparison though because there is still more plant material under the white light. Since he didnt measure the nutrient content of the plants, we can only make assumptions(what you said is true about darker greens). If you're getting your lettuce this way, its unlikely that the limiting factor is how much you can eat, seeing as thats like 6 salads in a month there. Each individual plant in this experiment probably has about the same total nutrient value, with the blue red just having a higher density. If you are able to grow all of the vegetables you need though, and your ability to eat them is the limiting factor, then you definitely would want to optimize the plants to be as nutritive as possible. Either way, people growing and eating their own greens is only good at the end of the day, even if they arent packing the maximum amount of nutrition.
@Mike E defiantly lol🤣
Get a quantum board. They're pricey but well worth it. Blue purple led's are no match to decent white led. White led in 3000k spectrum is perfect for all stages and will kick any other lights ass for efficiency and yield
Melanie Stewart I’m a novice too! I also bought a R/B light for my herbs. They haven’t sprouted yet . But hoping it works!
You grew this much lettuce in two weeks??? 😳 How.. That's insane.
Hydro is faster.
Hydro is less effort for the plant to send out roots to collect nutrients and water.
@I trigger people But it's pretty easy to keep conditions stable. Once you know the nutrients / light settings etc. shouldn't it be easy?
I wish I had found this video when doing my research about these red/blue lights. They suckered me in hard and I wasted almost $200 on them.
Thanks for doing the research so others don't have to.
Great video and its a good starting point, As it becomes more complex and depending on plant and requirements the LED type/wattage and spectrum i have found personally varies so much to get a good end result.
Think science is about having fun and the more people learn the more as a whole we progress towards results :)
Oh my baby. I heard red lights are better for flowering? lettuce no flower,that's the reason maybe?
Red light is part of white light. The ratio of red to blue is what matters. To put that into perspective, if you added green LED's to a RED/BLUE light, the light would appear white. The reason is that plants go into a type of dormancy when given too much of only a few different targeted wavelengths. Tuned spectrum lights can work better in certain situations and with certain types of plants, but that's the problem. One light that has a static ratio of target wavelengths cannot be expected to work as general purpose grow light. That's why white light is a fail-safe for the uneducated. There is no guessing with white light, it just works.
Robert Theref I’m aware. But this video is mainly about cheap amazon lights and second to that is spectrum. This video is not referring to all grow lights or every situation. Its merely a demonstration an observation.
@@TheMusicHeals.kjhjhhg I know that when I am growing lettuce for salad that trichrome production is the most important part. So I should make sure I optimize the lights for trichromes. On my lettuce.
@@toddschriver9924 trichomes on the lettuce.. lol .
