320w QB or 315 CMH

Nah no optics unless you don't have reflective walls. They throw uniformity out of wack and can cause bleaching, and they also reduce yields since the optics waste some of the photons.

Don't worry about UV. It isn't a big deal. If you're worried about UV for trichome production, just get a higher color temperature of the QBs (like 4000k) because the extra blue in the spectrum will do about the same thing as adding UV since blue is higher energy than say green or red.
Wow you obviously don't know shit about lighting, UV and blue lighting are not the same. QB's don't produce UV light.

F it, I'll get both! Lol

Idea, four QB one in each corner at different spectrums say 2700k, 3000k, 4000k, and 5000k. One CMH in the middle directly above canopy. Larger tent say 5x5.

Lol you are a certain kind of stupid. No use trying to explain anything to you because you can't comprehend it.

Can we stop throwing insults and help educate each other? I find that even with the most stubborn a good reference with case studies help people have a paradigm shift.

We have seen plenty "case studies" that Yodaweed and OneHitDone don't learn. Let alone have paradigm shifts. They are mostly just here to troll.

I don't have QB as I built my own and personally like my design better for my space. I built a 360 watt PCB possible build that I usually start around 120watts in flower then slowly move up and only until the last 2-3 weeks am above 250 watts to 300 watts. I have 4 of these lights and they cover a 5x 10 area pretty fing well.

I have CoB builds and Nanolux DE 1000watts that I have used.

Everything under my PCB builds look better when trimmed up. If my PCB lights grow equal to a Nanolux with a new Gavita/Philips bulb running at 1K and my lights grow relitivly the same with around 550watts then my lights that use the same diodes as QB are almost 2x better than HPS.

i have never grown with CMH and prolly never will simply because even if somehow it was better than my current LED lights, how much better could it possibly be? Not to mention the light with bulbs will cost WAY more than me building my own LED lights.

My Instagram below is mostly my PCB builds if you care to see.

Actually, Yodaweed is correct about the UV, and blue wave length.

I use both CMH and COB'S in my garden. I prefer the quality of the CMH buds, in part, because the UV gives them a little extra oomph.

Bad Karma, so the question then becomes, how much better? Does the quantom board yield a significant amount more at a marginally lower flower quality? Or is the "drop" in quality is so small that it is off set byhigher yields. And if QB LEDs can produce higher yields, how much consistently does it produce these numbers. Further consideration should be given to the seed. Are these numbers hit by fems, or autos?

I have yet to see any empirical evidence that proves one light technology has any advantage over another when it comes to potency. We've seen lab results that favor LED, but we've also seen lab results that favor the different types of HID. For that matter, you'll find a lot of HPS growers who claim to achieve greater potency under fluoros, but opt to stick with HPS for the many obvious benefits it has over something like T5s. There are far too many factors to draw a firm conclusion based on anecdotes. I believe that it comes down to personal experience, so if a grower feels that they are getting better results with any one light, more power to them, and may they continue to have great success. For my part, the weed I'm growing under LED unquestionably matches the perceived potency (and flavor) of any weed I've ever had, from any source.

"unquestionably matches the perceived potency"

You know, sometimes that's good enough. I'v seen many post with good looking plants under QB LEDs and CMH. I'm still very much on the fence. I want a 320qb that covers a 3x3 but they don't make that set up and I simply don' have the time or energy to build.

Where as the CMH is perfect for a 3x3. Also, I'm worried about light spectrum with the QB, will 3000k be good enough or should I add a 2700k for red and 4000k for blue. If I do this how do I set it up without favoring one side with one spectrum? I suppose I can rotate plant pots but the CMH would seem to remove most of that worry. Now, again, this is from my searching and reading, obviously I'm learning and can be very wrong in any of the statements made. Perhaps my worry is unwarranted.

Now, the 260qb led is set to 3x3 but I like that the 320qb has a mix of 3000k and 2700k, the 260 doesn't. I' l to make a decision on something today and pull the trigger.

One last note. I keep reading that Phillips stopped producing the 3100k bulb, these seem to be old post from 2016, is this still true?

Seems like that was bad info. I bought four of these bulbs a couple months ago.

Really like them in the Sun Systems vertical reflector. But I’ve never used LED, so I can’t offer any comparison.

Well I guess that's good to know.

I'll be pulling the trigger on something today. The QB is what I'm leaning to, I was reading a loooong post from captain Morgan using QB and he' ggetting really good results. My spacing is the issue, the board I want simply doesn't come in the space I need.. :-/

The CMH kit I'm looking at is $450+ so the QB would come out to be a little less. There's also the fact that there seems to be good endorsements from growers on this forum. I still don't get all the hostility towards Yodaweed lol.

If you read the first few pages of the "DIY with Quantum Boards" thread, you'll see why this forum is so hard on Yodaweed. A long history of talking trash to LED growers, and slagging pics of their plants, has resulted in him being persona non grata around here. He does seem to have improved his behavior recently though, so we'll see...

Are you looking at the 324 boards since your talking about mixed K I figure that's what your looking at, not the actual 320 three board kit? The 324 board is the one with mix of 2700k and 3000k, every other diode. They don't make them in kits and I think there to much for a 3x3 if using two of them. i have two in a 5 x 2.5. I'd get the xl260 kit for your 3x3, it runs higher wattage then 260w by alittle. 315cmh bud reminds me of 250-400w hps flowers from what I've seen but I only know one guy that runs one and not impressed yield wise but the flowers were decent overall.

Yes that's the one 324 with mixed diodes. I' j buy one kit but it doesn' sspecify 3x3. Do you fellas think it would be OK? Also, should I get a 4000k maybe a 64w 4k QB on amazon.

324 boards come as a set with heat sinks, nothing else so far. Would need driver 320h-c1400a, power wire, 18gauge solid wire, hanging kits. I don't think one 324 board is enough for 3x3. I'd get the 3000k xl 260 kit if I was using a 3x3.
