Petflora LOL, yes I did bulge... I already saw it. I like what you are doing with your bulbs. 
So for you XTE WW 3000K will bring all the 630 needed?
of what I red, 630 will make the bud growing and longer. when you add 660 the bud stop growing but its density increase and its maturity come quickly with plenty of trichomes production.
Is that true?
If only 660 is needed I can go for
veg spectrum: 2 XTE CW / 1 660 epistar
stretch and flowering before 3week : 3XTE WW/ 2 XTE CW / 2 660nm epistar
end of flowering : 3XTE WW / 2 XTE CW / 3 660nm epistar
According to lax123 the epistar from satisled are as efficient as the oslon 660 but 3times less expensive so I should go this way.
I fear a bit not giving my ladies some 630nm...

I'm not sure where you got the xt-e numbers... the R3 bin you said you are getting does 235lm@700ma running at 50*c...not 140lm.
http://pct.cree.com/dt/index.html use this for cree performance.
Yes quanta(umols) is more important. If using a more efficient spectrum you can use less to get same results...but still need a certain umols despite spectral efficiency.

Yeah your right I did a mistake, I check the cree XTE today, from cutter, my memory is not very good.^^
by the way even if I am going with XTE WW, I saw that 3W led from satisled are 200-220lumens. But I can not compare it because of the spectrum, and don't even have the datasheets.
Clearly I think there led are not so bad, but I have difficulties to believe they sell 660nm led better thn oslon SSL for 1,3$ instead of 4 to 5$.
tags420: what do you think of skipping the 630?
you said I should use 60° lenses but it seems a bit to narrow, I would probably go for 90°, at least for the led on the side of the pannel for better coverage; and the red because I fear bleaching.

Hm i think u got me kinda wrong.
If what i calculated is right -with that i didnt mean to say satisled r top notch but they r some lousy lying bastards
Their 4 year old datasheet would claim that those 660 r still better then latest technology...
Which company produces far better quality and technology stuff then shown in their data? I just said "dont be fooled"....

hum... then you are lossing me... what's point of calculating some stuff if you know it's bullshit? So satisled make led but we know nothing of it. they can actually put less than 500mW no one would no it...
I love the oslon 660, but their prices is too expensive. I will probably go with it. "you get what you paid" isn't it what u guys are saying?
Then I still have 2 things that bother me: should I put 630nm if I am going with 3 XTE WW and 2 XTE CW ? I would naturally try to balance the 630 and 660, but 660 is more effective for growing apparently, and XPE 2 and oslon are the same price so I don't care.
I saw that some guys use 730-740nm led all the day long and not only at the end and the beginning of days, saying in reduces the time of flowering and its better for flowering thanks to emmerson effects.
In my XTE WW I have some 730-740nm is that sufficient?
If I add some of these leds won't it make fluffy buds and make the pants stretching ?

First i have to calculate to realize that what they r saying is bullshit, right?
But on the other hand im thinking getting more cheap 660nm satisled would outperform more expensive ones because u can get so many more for the same price.
But i have no illusions about them beeing anywhere near that oslon quality and output 1vs1.
Its like tiny ants beeing able to fight one larger insect
Also with more but cheaper leds u can cover more area/spread the light, thats another + for me
What we would need is someone that has a spectrometer and some other devices/sensors to see how bad/good they really r.

I just ate and had like 5 beers, so bare with me... read, study, stop listening to others who haven't, and just follow some other dumb asses lead (including mine) PR (Photosynthetic Response) for mj is 650, not 660, 640- 650 is a ton less expensive to supplement.

for Whites maybe look into These: i like them and the Price tag, XML quad core http://www.ebay.de/itm/2pcs-Cree-16mm-XML-U2-Warm-White-3000K-High-Power-LED-Light-DC12V-1A-for-Torch-/221275663807?pt=LH_DefaultDomain_0&hash=item33850eadbf
i made some small experiments with 660 as only red, with tomatoes and kitchen cress compared to natural sunlight -i saw some crazy good root development, but of course that wasnt mj...

Utterly confusing, XML-U2? U2 is a bin, and sure as hell warm whites don't exist as U2 flux bin. I highly doubt that they are XML2's either. Sometimes I wonder if the Cree's you can buy from china are made by Cree at all, I'm getting more and more suspicious about those cheap deceiving little #¤%&¤.for Whites maybe look into These: i like them and the Price tag, XML quad core

Hi everyone,
Thank for helping me
First I agree XML WW in U2 bin is very suspicious I have always seen some S6 and T3 bin for 10$ the chip.
Then I had a little thought on this MKR:
I am in france, hence I can not import from many different suppliers otherwise the addition with huge shipping cost will b tremendous...
I looked at led.tech which seems to be interesting for us because the shipping is only 9$ and also steve led and cutter.
First these are the leds I could find : MKR WW bin G2 at 20$ on led tech and the same at cutter at 15,39$/ then come XTE R3 3000K at 3,5$ / XML2 3000K T5 at 9,89$
MKR put huge amount of lumen (let's not focus on spectrum as I will compare them with XML and XTE) but if we look closer at these led, their is a problem:
by going on the cree led site for comparaison, @700mA
I have MKR 106lum/W then consuming 8,5W
XTE 111lum/W consuming 2,2W
and XML2 143lum/W and 2,06W
I don't need to have the best led but the best efficacy/price/quality:
XTE are 1,6$/W MKR are at 1,8$/W on cutter and 2,35$/W on led tech XML2 are at 4,8$/W
Clearly XML2 are too expensive for just 30lumen/W more than XTE I can have much more lumen by adding more XTE and I will spread the light better.
Then MK-R are not as efficient as XTE and cost a bit more.
I will go with XTE so far...
If I was going in a comparison process like SUPRA I would take XML2 and other very efficient led to have the best efficiency possible and prove that 100W of led can easily beat 300W of HPS.
But I do not care about that... I just want some easy grow, with a great pannel, and having less difficulties with heat issues and fire safety. I fuck the gr/W ratio, I just want enough weed. I am sure you see what I mean
@Guod : I will look at LG, thank you, they do not seems very expensive.
Edit: so I looked quickly at it:
the spectrum in 3000K is about the same than cree, but maybe more blue than XTE
the efficiency is not as good, indeed it's less than 89lum/W @700mA...
the price is very low 1$/W so I can have approximately 1,6 of them for the price of XTE.
It's interesting but as we do not know the bin for the module you show me, the effiency can be less than 80lumen/W I prefer going with the cheap led from satisled I show at first.
Only a first quick feeling of course.
@petflora: Have you got a link of the 440-450nm supplementing led you found please? I am very interested in them if there price is low and efficiency good.

Hello,
sorry petflora I was obviously meaning 640-650 and not 440. stupid mistake.
Only 72lum/W at 1000mA? I don't get it.
if it's 12V then MKR are better if my memroy is not at falt they get about 90lumen/W @1A but twice more expensive
if it 6V then I never saw this XML but the XML2 3000K bin T5 from cutter is 111lumen/W @ 1,7A and it is about 1,4$/W not bad yeah?! (coming form the cree site you gave me by the way, great tool thanks very much)
it seems these cree are the less expensive led I saw. but efficiency is not very good.
something however stroke me: WW in U2 bin... first time I've seen this. I will look at this closely tomorrow.
If guys I can ask you help me with red I will be very happy. Because white is fine, I will make my choice between these XTE and XML2.
but for red I don't know what led to take.
I saw the ledengin from cutter which seems not to bad. can output more than oslon but they are more expensive and less efficient.
and then there is still the question of 630 "to put or not to put". but when I see result from area51 and apache 630 seems good to add with 660.
