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''....

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 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

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

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!

I think that what you are seeing is full spectrum continuing to support leaf and stem and perhaps even root growth, when in the last portion of life the plant needs to send that energy to flowers and fruit. This suggests that full spectrum may be best for the first half of a plant's life and burple for the 2nd half.

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
@GrowingAnswers 8 жыл бұрын
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.

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

very interesting. Questions: 1) would you say red-blue light only became deficient after big canopy has developed and won't be matter for smaller plants like lettuce and herbs? 2) would adding more blue and some green LED's (instead of whole spectrum white) equally address the problem of light penetration 3) was there a possible flow in the experiment that your red-blue light had only 10 blue (responsible for plant growth) LEDs? The 2 reasons I think of not using white are: 1) they know to lose some intensity with time (due to phosphorus burning out) 2) possibly less efficient than pure RGB?
@GrowingAnswers
@GrowingAnswers 8 жыл бұрын
You are getting into having to tune the amount of light you would need by adding other wavelengths. And even more so, having to figure out what specific wavelength is needed. Throwing a bunch of different colors at a plant can just oversaturate the. The blue to red ratio is specific to plants. off hand I don't know for sure, but this one would favor flowering phases, but is ok for general purpose (as supplemental). The experiment is about showing what happens with the 2 main wavelengths. Yes, canopy penetration is effected by means of the red blue as seen in the video with no lower growth. Shorter plants grow well (like lettuce) under just red/blue, but the rule still applies; you get a better result with full spectrum. White light LEDs burn out all the same as any other color led. The phosphor doesn't really burn out, the LED does and the phosphor if it's not remote, can contribute to hear build up on the chip.

Big Al Its true white aren't as efficient as individual mono filled pcb lights. But the whites are easy to install, and cover the whole spectrum nicely. The intensity from them allows for a high PAR and umol which can be better than having a perfect spectrum. Green wavelength is reflected from the plants so it won't absorb it (not good for growth). Cree did a study with XML3 I think and some far red and blue monos to compare against a gavita 1000w at half the power.

Why not try growing a white sage abd see if the germination rate will rise in indoor growing

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...

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

How can you compare these without giving us the info for the COB? so many variables not covered like lumens per watt, par values etc.. Good idea on this experiment but you need better controls.

That's why the most new boards have 85% white (different types mostly 3500k, 5000k and some 7500k)and 15% of the two outer spectrums like UV and on the other side IR!

From your first video I got the impression you thought the blue/red would outperform the white LED because whereas the white LED was full spectrum, the plant didnt' really need all of that and was therefore wasting wattage on unnecessary spectrum while the blue/red light was somehow more efficient for the plant if not for the lower wattage which you were going to offset by equalizing the PAR performance of both plants.

Candy Sweet the first video was labeled as educational to set a foundation for people that have never heard of the red/blue grow light. It’s simply an explanation of the facts and the hype.
