White LED vs Red/Blue LED Grow light Grow Test - Part 2 (The Grow Results!) 2016

Part 1 • White LED vs Red/Blue ... (Educational)
Part 3 • White LED vs Red/Blue ... (Par Measurements)
Part 4 • White LED vs Red/Blue ... (Final Results)
2018's Red/Blue vs White LED - • White LED vs Red Blue ...
White LED VS RED/BLUE/WHITE LED Grow Test Ep.1 2018
- • White LED vs Red Blue ...
White LED VS RED/BLUE/WHITE LED Grow Test Ep.2 2018
- • White LED vs Red Blue ...
In this video I show the results of the grow test talked about in the educational video, part 1. I also go over some technical aspects of lighting used and light in general. The results were very surprising and you can clearly see the winner. I would not have guessed what the outcome was by any amount of reading on the subject of plant science. The experiment was a success and worth it. There was no difference in the amount of flowers produced under either light. however, the white LED started producing flowers in more abundance first.
As a side note, if you would like to use red/blue LED as non-supplementary lighting, it would be ok for leafy greens like herbs or lettuce. There was little difference in leaf growth between the 2 lights, but if you are consuming it, the quality of it may vary depending on spectral output.
There will be another grow with this setup and I will be making another video showing PAR readings so subscribe if you would like to see more. I do this for my own benefit and knowledge and it costs me money, but making a video only costs me time so I hope this is helpful to some. I know if im looking for information, a video may only have one part within it that I find useful so I hope if you don't find this video helpful in its entirety, you at least get something out of it that you were looking for.
Thanks for watching!

Great info, and I was really glad that you went off-topic a couple of times too as it helped us build "bridges" between subjects. Very knowledgeable indeed!

Thank you for doing something I've wondered about ever since the very first generation of grow LED lamps came out.

[@bernadettekennedy2981]

Your explanations are very helpful. I like to know what I am doing. Don't have any indoor sunlight and have been very frustrated with dying plants and orchids. So now I feel I know what to do. Looked at many other videos and they just left me asking questions. For instance It's good to know that red is weeker than full spectrum but helpful for fruits and flowers.

[@mrgulabull]

Really appreciate all the detail. I've learned more in the last 40 minutes than I have in days of researching various websites. What I'd love to see is a comparison between the various whites. 5k, 3.5k, etc. Thanks for sharing and please keep it up. You've got another subscriber!

[@apple-on5pq]

@G Hollis actually 4k is neutral, 5k is consider as cool light

[@orion9k]

I use 6000 kelvin light which looks clean white - some people call this studio light, cos it reflects all surface colors as their original color instead of manipulating the surface into having same color as the light source.. therefore, white light is what I would call full spectrum light, but for some odd reason, the industry calls red and blue light ''full spectrum''....

[@apple-on5pq]

@G Hollis your reference said that "Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700-3000 K) are called "warm colors" (yellowish)".

[@apple-on5pq]

@@orion9k all white light considered as full spectrum because it contains red green and blue light. Also the colour temperature (K) is the colour we (human) see in the eyes, its doesn't contain the same wavelength as the sun.

[@orion9k]

@@apple-on5pq what does not contain the same wave length as the sun? The suns wavelength depends on the time of the day

This is the best information i got since trying to grow cannabis. I mean with so much information going around, i recently purchase flood light like LED 4000k 50w and people tend to tell a different story before i decided to grow. First it was lumens, lumens became LUX and recently diodes of the LED wont be enough but you debunked all the crap i was told in this vid and i am half way thru it only. Thanks allot this had definitely saved me some money. Each person i had shared my idea on growing keep suggesting expensive grow panels with built in fans etc, yet from the results with this vid i am convinced it is possible to grow with budget flood lights LED

[@WolvesAssault]

Just updated I was ordered Spider Farmer Grow Light SF-1000 LED last Nov 2019 on Amazon. My Jade succulent lots improved lots strong thick stems from white light much better no more leggy/collapsed, I stopped use red/blue light make worse leggy/collapsed on my Jade succulent because lack full spectrum light. That why I founded your video about tomato grow went collapsed under red/blue light, I just shocked same my Jade succulent.

This video series is the most helpful I’ve seen on grow lights ! Thank you for taking the time to do this . I have over 100 succulent plants that I keep indoors . I want them fat , colorful and healthy. I use T5 fluorescent grow lights and I love them so far . Have you compared white LED to T5 ? Do LED ‘s make a real difference in the electric bill ? The only way I wanna switch to LED is if the electricity bill will be Lower and they cause better growth 😊

[@GrowingAnswers]

LED has better spectrum and the good ones are far more efficient than fluorescent.

[@littlebeebs1]

Growing Answers , Thanks for the reply . Did you truly see better growth with LED ? Any brands you recommend that are affordable? I’m just a hobbyist. Not looking for super expensive. I usually like to use 2ft by 1ft lights so they’ll fit my shelves . My favorite T5 light only costed me $77 😊. Looking for something under $100 . Thanks again 😊

It would be interesting to see if there is a difference between the grow chip you used [that use red and blue LED,s] and the ones that use blue LED,s and use a phosphor to produce the red and blue color.

[@jem02081]

enjoyed the full length versions of parts 1 &2! (haven't watched part 3 yet) I wouldn't want to see the video shortened. Would have been interesting to have collected the total weight / mass of each plant as a measure of the effectiveness of the lights in supporting plant growth. Also, @ 3:30 - 4:00. I don’t understand the penetrating the canopy comments. OK, green light penetrates the canopy best (photons absorbed the least?), but aren’t the green wavelengths of little use for photosynthesis? Also, with respect to the red vs blue canopy penetrance. Is this an efficiency of photon capture difference? Or is light scatter or something else going on? Thanks

[@godzillazumagod9146]

Good video. I want to grow some sun flowers.

[@MisterMeaner111]

Awesome Video! Only thing I question on the method is trying to "veg" a plant under such heavy red spectrum. From my experience, you would receive a better result under a 2/3 Blue, 1/3 Red LED mix. Heavy red spectrum is from my understanding for the flower/finishing stages of growth.

[@GrowingAnswers]

You are exactly right. However white lights can be used for the whole process. This was just showing what happens if you just use 2 wavelengths that are said to be all the plant needs. If you want to change lights during growth phases, that is just to try to control the veg/flower period and tomatoes will flower no matter what. There were no more flowers under the red/blue light than the white.

[@TonySlug]

Interesting. Good stuff. The red/blue plant got about 20% less true wattage though, and that's a big difference. So comparison may be a little off.

[@Roman-vk6od]

[@combatmako]

Interesting indeed Well Done ! ✌️❤️😁

[@1kcrit339]

Most growlamps today have a mix of all spectrum's. You have valid point about white LED (i would guess 4000 Kalvin )it is much better spectrum to veg due to stimulating hormones however the plants flower much better in red/blue (about 2500 kalvin for red light and 6500 kalvin for the blue light) and that will also stimulate a hormone like "Flower as much fruit you can before dying" type of hormone. I can explain this and its vary simple, Spring and summer time have a much brighter spectrum so that the plants have a greater chance to stretch and grow big thick stems so t can carry as much flowers and fruit it can before dying. Where the sun attends to turns red at Fall to give that boost to mature the fruits and terpenes so it will attracts animals that can eat it and spread the seeds before winter (most plants harvest sep - oct (Depending on where you live). Tomatoes produce flowers true out the summer time but gets really juice in august (Because the sun turns more "red"). Btw the Cannabinaceae Family is quite big so pretty much means you grow tomatoes like you grow cannabis. Have a good day!

[@anyshitt]

[@jrmint2]

This was a very interesting video...I learned a lot! So I purchased 8 led shop lights, 4ft, 20w, 2200 lumens 6500k for my plant shelves to grow mostly herbs and greens like lettuces. In your opinion...How many lights should I put on each shelf? I currently have 3 per shelf. Not sure if I need more or less...

[@GrowingAnswers]

RiseUpBlue should be plenty. Proximity matters more than light output. Adjust distance based on plant health.

[@nlgrowdr8441]

Good vid, like the info, just an observation, you said you wanted to start and grow them with the same light as it may impact growth, but then you did just that. Did you not throw the experiment right from the start by doing this? Good info, but a little concerned on the QAQC by starting them all under the same light source. Cheers

[@pal98111]

Super educational. Thank you so much. I grow high light orchids under T5s and have avoided LEDs because I don’t like the purple color. I used 3000k and 6500k tubes. Is there and optimum LED temp. For growth and flowering? You mentioned in Part 1 the white light was 5500k and then had 3000k in the experiment. What would be best? I’ve never noticed if they have warm white and cool white LEDs.

I do appreciate your testing of the led grow lights. Can you reply back to me regarding what is actually the best lights for using growing tomatoes and peppers indoors. I’ve been spending too much on buying grow lights just to grow my hot chili peppers and dwarf tomato plants indoors. I did watch your videos testing the growth of the tomato plants. I’ve, also watched many other videos about most everything regarding the technologies of the many different types of led grow lights ranging from expensive ones and cheap ones. I just can’t even make the right decisions of what is the right grow light to use anymore. I just kept buying many different ones try growing my plants healthy indoors. But, do t stop with your experiments because it does help us viewers as to understand more of how we can grow our plants indoors. And I for one, grow indoors due to health issues and I’d like also to continue to grow due to the seasons especially winter. I bought a spider farmer light which is very expensive but I have to return it because it was missing a control panel that should turn on the lights or something. I’m not gonna turn in and if the grow lights by plugging into electricity every time and then unplugging it to turn it off which is ridiculous. Anyways, keep up with your videos and we all can keep getting more information from your experiments that does help us gardeners whether we plant indoors or outdoors. Most of all we appreciate you for sharing with us your knowledge and experiments. Thank you

Is the white LED same as conventional LED used in houses or it is specific for plants growth only?

[@Geoff]

Hi, I'm trying to figure out what color temperature I should use for my white LED. Do you think the lesser kelvin temperature on the white LED made a difference compared to the higher kelvin white LEDs around the 5,000-6500k? I tend to hear that higher kelvin temps are "better", because it is whiter but to me they seem more blue then natural sunlight. I am choosing between a 6500k led vs a 3000k led temperature. Thanks! Both videos were really helpful for me.

[@GrowingAnswers]

Its just overpriced florescent on steroids. Yeah they last, but so do LED's. Fluorescent lights dont really have a uniform spectrum either. It has peaks in certain bands. That have sort of a weak penetrating power too.

[@libeshbalakrishnan8840]

thank you...

[@Lquiyasm]

This was very rewarding, congrats on the good work mate, regarding the color temperature choice for white LEDs, lets say i pretend to grow, seed to harvest, only on withe COB leds, would it be better to use cool rich on blue light leds, or warm leaning to red spectrum leds? thanks in advance

[@GrowingAnswers]

Lucas Maldonado you could you any, but red dominant will give better yield.

[@Lquiyasm]

Thanks mate, that was really fast, now diggin a little deeper, how is it that, photosythetic absortion spectrum (PAS) has a higer peak, promediating clorophyl a and b, in the blue light wave lenght and photosynthetic absortion response (PAR) has the higher peak arround the red light wavelenght, what is the explanation behind that? i can see that it is the justification for the plant "wanting" to get more red light but i cant see the correlation, hope my question makes some sense, sorry for the shitty english :D best regards!

[@GrowingAnswers]

Big words and phrasing is giving me a headache, but I think the answer to that is the dominant color of the chlorophyll pigments is green. Green absorbs more red by filtering and light in the red spectrum is highest in demand because it is mostly absorbed by the top part of the plant. Blue light peaks higher in response because its more efficiently utilized by transmitting more through the leaves and therefor is absorbed by more of the plant. That's the general answer. This is why plants need less on the blue side of the spectrum simply because they respond to it better with less than, in terms of energy vs red. I'm no scientist by any means so if you want to get down to a cellular level, I would advise to google that.

[@Lquiyasm]

it makes sense, thanks man really appreciate it

[@fibo7626]

Just curious, you had mentioned in a previous upload that you would adjust the par to other light. If the LED were design for short but wide growth as you had mention regarding the cannabis influence. If you had lowered the red/blue light, would then the plant could focus on leaf matter instead of weak steam? And perhaps the actual production of usable material would be a higher yield?

[@GrowingAnswers]

The light spread is all that is effected. Neither LED has a lens for focusing so you only loose light coverage by a few inches outside the center of the light. The plants on both side are both well within the main footprint of the light no matter the height. The light housings themselves are almost as big as the area as they are touching the walls edge to edge and width wise.

[@fibo7626]

Thanks for clearing that up. your project is an excellent presentation.

[@nikoodaha1645]

Great info, thanks for the video Can I mix both white and red blue LED together? Will I get better result?
