Based on what exactly? Are we talking facts or Bro Science?

Just look at the chart it's pretty simple to read, which spectrum would you go with if they had the exact same output? I know which i'd be using.

They highlight the 3100 Agro bulb as the best for plant growth. 2nd is the 4200k.
And for our specific cultivar and even higher ratio of red than either helps our flowers. That’s why they are really recommended as supplemental to hps.
I like 2 hps to one cmh personally. Better quality and bud structure without the size limiting compaction the blue heavy spectrums cause.

I ran two LEDs(red white combo) and one 4200k CMH last run, frost levels off the charts nearly two pounds from 550w of lighting.

That just proves you did well with those lamps. You are arguing about picking 1 cmh.

I ran them together, in a 4x4 tent, two plants were grown hydroponically and two in organic, got some pictures on my IG

Which light do you feel did better though? Not trolling brother asking an honest question as I'm debating switching one of my 3x3 back to a CMH from LED.........

I like both, in my opinion both got different strengths and weaknesses, the cmh can be hung higher than my LEDs and also requires a bit more height to canopy, the LEDs definately brought a ton of colors out and no worry about burning my plants they can get very close, i really like all different lighting situations for different types of grows/techniques i also still use HPS lights. I think if you are going for purely weight the LEDs in my opinion are the best because spectrum is so high on par output, but for quality in my opinion the CMH is better.

Cool thanks for your input. I also am using a mix of hid and Led......

I got that going right now too, LEDs in with my HPS i use my LEDs as side lighting for my HPS area, it works great.

Had my 4x8 all cobs but put my 600 hps back on one side

You supplemented your 4200 with red led...it's not much of a comparison in that way. I bet that setup would work good. I'm pretty certain my future holds 200w of COBs that are dimmable and mix with my 2 315's. Thinking some Citi 1212.

I am testing the 3100k 4200 bulbs and I have a cmh 400 watt ballast with a 2100k bulb to see if I notice a difference. I agree the 3100 has a tiny bit more par. With our cmh bulbs it isn't about the par like with HID. Sure we want great par but its about usable light for the plant in photosynthesis. The 3100k and 4200k both are excellent bulbs. I have more experience with 4000-4200k grow lights than I do the 3100's which now makes it so we can mix them into the grow to see what works better. I have not noticed a big difference between the 3100 and 4200 so far. The 2100 is showing less resin and trichrome production as I thought it would do. I do notice a bit tighter buds which tells me what I also thought. The lower the K the tighter buds. I think we all are lucky to have these new LEC lights to use. I currently have 2 630 DE with 3100k and 4200k bulbs. 7 lec 315 with 2 4200 and 5 3100. 400 cmh with 2100k bulb. 2 1000 watt super hps Hortilux all being used and the LEC is kicking HID lights ass. Hope you all enjoy the lec lights as much as I am.

Which lec are you running? Also what ballast is pushing your 1K hps?

I been buying the cheap complete units on EBay. I will down the road switch them out for better warranty ect but right now its all about how much I want to spend. when I get done I will have around $3300 in lec lights and if i did name brand lec it would be $7k for the same amount of lights. I can say this if you get a 630 DE lec get a xl hood as it helps tons with heat disbursement. I have a normal hood in one and the heat under the light is insane(using for veg) and a xl hood which spreads the heat over a wider area and its allot cooler but still has allot of heat.

When you say it's not about the par, but useable light...par IS the useable light. Photosynthetically Active Radiation. These are really efficient HIDs. We can run em open hood in tents and utilize the UV. 3100 has more reds, which are desirable for flowering, and has more photosynthetically useable light. What I would say is who knows what effect different spectral compositions have on terp profiles, but it does. The only way is through experience and apple to apple comparison.
And I feel like I'm coming off like I really need a toke right now...I'm just obsessed with logical reasoning...lol
I'm a little skeptical of plain 4200 having a better bud/leaf ratio than 3100 without supplemental red. Mixing them in configurations might be interesting though. I get too obsessed with symmetry for it though.
