Any ideas as to what negative ways some may respond to too much red,660nm? Or are you saying some may just not benefit as much?
LED strip gurus around here? Stop by and check out this vertical setup that needs tweaking!!

I’m also hearing that @Prawn Connery ‘s boards may be priced in a similar range...a very good deal for their quality design and expected performance (which i plan to confirm with a smackdown grow).
If you live anywhere close to australia, contact the prawnster, his boards will be available anyday and you won’t be able to beat the price/performance on them, especially when you consider shipping costs.

Some strains react better with a more balanced spectrum, I wouldn't say heavy 660nm is a problem as such but some just work better with a more balanced spectrum, I'm using 4000K 95cri as a base spectrum now because of this then tuning to be done to change colours. There is not one ideal spectrum apart from sunlight. It takes a really long time to test spectrums for specific strains. Once you know what colour works best for you then you can make a decision as to what exactly you need to get maximum production. Not enough research has been done on this yet and there are so many strains around now that noone really knows what is best, a salesman will tell you otherwise.

I’ll bet that this spectrum is pretty good with any strain:
And i’m not a salesman, nor do i particularly like hlg.

That spectrum is pretty balanced apart from the lack of blue in the 470-480nm region. 
This one is alot more balanced, it's lower on efficiency though but if the plant is happier I think it makes a big difference. A fully balanced spectrum will allow the plants to take what they need like they do with sunlight not just do the best with what they have. I'm not saying it's ideal for everything but it's a good base to then allow you to make modifications to the spectrum with mono leds or narrow phosphor converted leds

Are you making that one?
Prawn will tell you, i don’t necessarily agree that mimicking the sun is the ultimate goal...especially that 500-600 range... tho i do like both tails....but i’m willing to be proven wrong....

You will be able to buy that spectrum very soon in a strip format. Because it's done in strips you can then use monos or more focused phosphor converted colours to blend the spectrum to what you want in particular. If you want more red for example you could use just a bit of PC red to completely transform the spectrum from a 4000K to a 3000k. By pc red I mean this
It doesn't take alot of monos or focused pc colours to change a spectrum by quite a bit. Efficiency does drop when doing things like this, but once you know for sure exactly what you need then you can plan you next build and be absolutely sure that the spectrum is perfect for you and the strains you want to grow.

My focus isn't on efficiency anymore, I've done it all already and so has most others, getting high efficiency is easy, I'm more focused on light quality for the plants as I believe that the overall results will be better. I don't believe the current way we are measuring efficiency is correct either, If a plant responds and grows better although the efficiency is lower according to PAR then that makes it more efficient if that makes sense.

I grow specific strains one grow cycle, then move on....so i’ll never be doing that type of intense study and precise targeting. There are just way too many gene combos out there, even within specific strains....
maybe commercial would like that to be the case, but i doubt their customers want to buy the same strains over and over again...
Perhaps would work if they are growing for specific to-be-refined cannabinoid compounds.
But i do understand that we are now at the dawn of tunable spectrum...just don’t yet have convenient circuitry/multi-channel controllability...

I totally agree with this, incremental efficiency is for high output commodity production...
as i told prawn, focus on improving cannabis quality, only build in dramatic efficiency improvements....

We have had capabilities to tune spectrums for a very long time, the main reason it doesn't happen is because it costs more and is slightly more complicated for the average grower

Then we don’t really have it....
We have it when the dumbest grower can easily and inexpensively tune their spectrum using a recipe off the internet...

All colours of the spectrum in my eyes are equally as important as each other. Having the right spectrum will improve overall quality of what you are growing, it may not produce the highest yields but quality and yields are 2 very different things.
Dumb people are just straight out dumb and it doesn't matter what you give them to grow with they will still be dumb, dumb people come up with stipid phrases such as "LED deficiency" because they have no idea what they are doing themselves so they look for excuses. Dumb people are usually the first ones to react defensively to someone that has more knowledge than they do also.

Got to go...but will try yo return to this later...i disagree on both, first one i already redonded to (ie mimicking the sun), second one: issue isn’t dumb people it is the common tech acceptance problem...ask larry ellison of oracle about his internet computer that failed...and how smart phones succeeded...

That's a pretty good grow for such low power, I'm impressed

Don't be impressed, use it as motivation to inspire you to achieve equal or better results, become a better grower.
Long story, short. I'm a sixty's year old man that's grown weed since the early seventies.
