Which QB to buy

Pictures of growmau5 weed grow does not justify cobs have adequate light the spectral graph shows cxb cobs and the addition of red and blues fills out the spectrum. Cobs do not provide the total photosynthesis energy available to plants just the minimum. Pretty pictures of weed grow but light efficacy and efficiency is not determined by watts alone.
Btw, thanks for proving my point. You provide pics of fan club leaders grow like that is the bible while down playing science. Some of us have been growing before some of you were in elementary school before google and such.

Current crop of crow leaders were kids on my last run and I knew the men that held those screen names for more than 20 years
Well if thats a pic of growmau5 used to argue all you need is white only thats kind of backwards. The reason its backwards is because he is adding other reds to his cob and quantum builds to improve performance. His latest video is about what he calls "light recipies" and the emerson effect where he's recommending having different colors on different channels so you can play with balances of whites, reds ect.
I would have actually used growmau5's video as supporting evidence for what vegas is saying, not the other way around. Discussion like this is awesome but i get the impression that BMHC is being rather agressive about this and letting personal opinions shade things rather than evidence in science and real world results.

Meh i already know what direction im going and its definately not white only.

Actually, that pic just happened to be one of the first quality pics to pop up in my search, so I used it. Nothing to do with where it comes from. I don't care at all where it comes from, it could be anyone. Point is, there are plenty of people getting excellent results with COBs alone, and your insistence that cannabis needs an enhanced spectrum to grow properly is just plain wrong.

What personal opinions? See above.

I plan on adding reds and UV to my little cab light, but not because the plant needs that in order to grow properly. White light leds produce plenty of light across a large enough spectrum to effectively grow cannabis, that's just a fact. No personal opinions or aggressiveness whatsoever.

Okay cool, then you are just having an argument about semantics and arguing for the sake of arguing. Thanks for clarifying my misunderstanding. Everyone is in agreement that reds and UV make the plant grow better and healthier, why argue at all?

Yes thats me being a smartass and sarcastic about it. I type this with a grin on my face and hope you can laugh about it cause its meant to make you laugh not be angry and let ppl focus on making healthier plants.

I just want to keep people from being misinformed, that's all.

It is a lot more than a few mono's If that was the case, Kind led, Flurence and others would not do what they do and use 5w and 10w cobs with more than just 3500k or 5000k in therm real colors and spectrum including full spectrum. Light Spectrum is NOT kelvins or cri Plants need a broad spectrum of light from 380nm to 830nm to grow and thrive, and not just a few mono's for S&G like I see from some folks with blinking lights and looking pretty but not worth the time or money.

Take a McCree graph and overlay your favorite cob cree, Vero, or Citizen cob over it, and see how much light spectrum is left over. That leftover spectrum is called the meat, what you have is skin and bones with just cobs. Two years and you guys are still waiting for a full meal. I experimented over the last two years, not on youtube or elsewhere but in my basement. I shared what Vitally is doing but that does resonate with your view of things. I understand. science is hard work, and growing and smoking weed seems easier.

Instead of continuing to wait for what others tell you is happening, get informed, buy a botany book, read led magazines and articles, read and study plant biology and how photosynthesis works and is influenced by various factors including light quality, quantity, and spectrum. I did when I was younger and I learned a lot. I did the Far red and Deep red sunrise/sunset for over a year now and already have expectations.

regarding pictures, no coincidences in life is my philosophy. maybe you did not look for that particular picture, but that is what was in your view and reach. VFery telling. It would not hurt to look outside the box of Growmau5 or others and have some real learning and understanding on yourm own. It does not hurt it feels good in fact.

I am not asking your permission or agreement, just pointing out the obvious, and you keep making my point for me.

You still don't seem to understand, so let me make this as clear as I can for you. I don't care what your background is, what research you claim to have done, or where you are getting your information. I'm sad for you that you believe my choice of image makes me a "fanboy" since that is clearly more important to you than the topic at hand. To busy hating to actually read my posts. You claim to be a scientist, yet you can't seem to grasp the fact that you are wrong. Plants do not need supplemental red, blue, uv, or any other wavelength in addition to white LED light to grow properly. That simple fact can be checked very easily with a quick search around. In fact, you're in the virtual home of that very concept. Literally thousands of people are doing just that at this very moment. How can you possibly argue with that? Yes, the introduction of varying wavelengths can produce different results, but they are not at all necessary.

On a side note has anyone payed duty on a quantum board to the uk just wondering what's it gonna cost me if I order one?

I smoked so much that I don't know how I got here; I didn't read the title or any messages, and I don't even know why I might have found this thread interesting.

You need more red and blue with 3000k I would add a full spectrum to fill in the gaps easier and cheaper. If you are running 200w driver I would add 50w of full spectrum for balance. Full spectrum adds from 380nm to 840 nm far red deep uv ir royal blue and some green all in one cob. You can buy more expensive but they perform similar to the plant. I use fs and schedule deep red am fs all day fr evening and done with cobs on at full power no diming. Reds do wake up and night time.
But... will one 50W chip light up whole 80x80cm tent? I doubt so.
So it's better to mount more diodes ... 660 + 730 + royal blue on heatsink?
