Well...
Let's just say ,that I've pretty serious indications,that above a certain "irradiance threshold" ,
then all what's needed is just white light..It will do just as good -if not better -as white+red ..
Though ...
NW or WW(5000-3000) + deep red ,is a combo that indeed ,packs some tight and dense buds,
by far than anything else ...
( At least until some really efficient and powerful 2700K WWs ,show up ... )
Still ...The 3000K WW ...If 'given ' to plants at high irradiances ....
Will -probably-do the trick... ...
All along ,from seed to dried bud ....
Better wait for the evidence /proof,though ....
...
Cheers...

I actually hate talking bout' best spectrum. My mind is constantly fluctuating in possible directions.
I'll be watching all these 3k runs closely...I got nothing against easy. Like you said, it may just come down to a high irradiance of warm white.

I mentioned them once...because i suspect there are Reps of theirs in this very forum...other then that....they are just another LED panel making company to me....
So stop making up lies about me please....

Show me where I ever said BUY THIS LIGHT, though I am close to saying it NOW, and after only one week.
I always said it is worth considering, an option to the others.
That you don't understand plain English is a testament to your education
It is the few, like you, who seem unable to put 2+2+2 +2 together (Quality Diodes + Quality company + 3 x 3 homogenous footprint + Choose your own spectrums) that confuse the people looking for guidance.
My agenda is clear, yours not so much
I back my comments up with regular pics in m thread.
Where's your thread Big Mouth?

well thanks for proving me right that you get emotional when people get tired of your BML spruiking and yes your agenda is quite clear....

I will continue to post pics of BML in action to prove its' value, and you will continue to ... ?
Where's your grow thread again... lights, camera, action

From that very article:
Far-red Supplementary Far-red Supplementary Combined EE delta C_ (B +A)
1. 713 (100 %) 653 (57 %) +15.5 +49.5 +73.5 1.55 8.5
2. 721 (57% ) 653 (15%) + 5.0 +14.0 +21.0 1.40 2.0
3. 721 ( 57 %) 653 (57 %) + 3.0 +36.0 +43.0 2.33 4.0
4. 721 (100 %) 653 (57 %) + 6.4 +42.6 +57.1 2.33 8.1
5. 721 (100%) 663 (57%) + 8.0 +55.8 +69.0 1.65 5.2
6. 721 (100%) 668 (57%) + 6.5 +53.8 +65.4 1.79 5.1
7. 730 (100 %) 653 (57 %) + 2.8 +45.2 +58.4 4.74 10.4
* These wavelengths were obtained by the use of second order Bausch and Lomb interference filters combined with
sharp cut-off colored glasses. The figures within brackets indicate the different intensities of light used as per cent
of the total available.
The highest Emerson Enhancement Effect (in this study) was 653nm red with 730nm far red. Which is rather close to most other studies. It does very slightly between species, but in general it between 729-744nm far and 650-667nm deep red.Far red below 720nm always has diminished returns in comparison to >720nm. There are literally thousands of different studies on Red drop and the Emerson Effect.

Pink and purple spectrums are the best.

more farred then red will double your yield, believe me and have nice grow.

Is that the Emerson Effect is not between 680-700 as CK stated or 650-700 as you stated. It is the use of deep and far red in combination with each other where the difference is at least 60nm that create the enhancement. The best recorded results were in lettuce using 732nm and 661nm.

But what about 2 to 1 660nm to 730 like Illumitex does? It's just really hard for me to believe what you're saying because I couldn't imagine 2 to 1 730nm to 660nm growing more weed.

320w white..30w of far red to play with. What would be the right amount. Options 10w..20w..and 30w. Why do I have the feeling I'll be going into hemp production again
Thanks for all the help guys has lead me to research alot more into it and think going for something like this would be far better than i originally proposed,still felt i needed a little more blue in than the 10% suggested but feel free to tell me if i am taking the wrong aproach with this 1.
730nm- 3
660nm- 10
630nm- 8
4000k- 5
380nm- 5
6500k/450nm- 3
420nm- 2
730nm- 3
660nm- 10
630nm- 8
4000k- 5
380nm- 5
6500k/450nm- 3
420nm- 2
After reading into this a whole lot more i fail to see where your getting this information from as too much far red induces stretching which does not as far as im aware help atall with yield

no you are wrong again. 730 has nothing to do with Emerson effect. I used to think it did too. It has to do with phytchrome state.
since you like to quote and cherry pick wiki lol
http://en.wikipedia.org/wiki/Emerson_effect
here is more reputable sources of info

Quoting a source that states itself that "needs improvement" and needs further siting isn't suggested.
Are you saying that a wavelength of light can not perform more than one function? Yes, 730nm has a major part in phytochrome production and the Pf/Pfr states.
Here is a link to 53,800 articles/studies on the Emerson Effect.... greatest performance is with wavelengths greater than 720nm. You know... just like the one you linked before that stated the same thing.
I have come to the full conclusion that you misinterpret/troll everything, due to the few interactions of straight shit you have spewed from your keyboard when you post. I'll disregard you from now on. It gets old proving the village idiot wrong. The best I can hope for is that you pull me down to your level of stupidity and beat my with your vast experience.
