Weezard,
I know its weird but the white light just seems to work. That is why people always recommend throwing in CFLs with a LED grow. I have a 180watt UFO R/B/O and a 90watt UFO R/B/Warm White. Both are vegging plants in a 2x2 and the 90watt has been giving steady growth and great results while the 180watt has been somewhat lack luster.

Umhhh..yes, its RGB, but white LEDs emits on a continuous spectrum from 430 to 750nm. They gives off some far red, that is important for bud's rippening. And the continous spectrum seems to compensate our red-blue extreme spectrums, improving their perfomance.
Each day I tend to use more white. Guys on the spanish forum using the bluiest spectrums with little white are having problems with THC development (not resin) and plant's rippening, while other using more white, not
And the difference from not using white to some white added is clearly enhancing spectral efficacy.
Maybe with more study we may understand exactly what white adds to the spectrum that improves it, and in the future we can use just the wavebands involved, but right now adding white is giving the best results, IMHO.

Plants do use green, they use the whole spectrum just in differing amounts of each part, green is used very little but it is used so should be included along with UV and IR.
You worry about giving your plants all the balanced nutrients by providing micro-nutrients so they can grow their healthiest.
You need to do the same with the light you give them.
Leaving out spectrums is like leaving out micro-nutrients, the plants will grow but not to their best potential.
I would even go so far as comparing heat from the lights with ph in the nutrient solution or soil, too much or too little heat and the plants suffer like they do with a ph imbalance.
LED lights can be the lighting equivalent of a properly balanced nutrient supply at the correct ph level.

I'm Back with another light What Do You All Think of This One http://cgi.ebay.com/NEW-120-Watt-Hi...emQQptZLH_DefaultDomain_0?hash=item2a01d5f22e Thanks, Tricky

Newbie here, trying to learn: I was going to build a 4' X 10' with veg on one 4 X 4 side and flowering on the other 4 X 4 side
scratched that area, and decided to replace an unused wet bar with a grow room; the bar footprint is about 5' x 5' ; for an indoor grow, what's the best height/size for flowering, and for vegging??
I'm mmj licensed, allowed 12 plants, 6 in flower, and 6 immature, although I'll probably be trying to cycle the grow into 4 plants every 3 weeks or so.
everything's possible at this point, I'm here to learn

Well, which is it?
Well, which is it?
"
LED Configuration - 112 Watt LED, 88 Red (660nm) + 12 Blue (455) +12 Orange (615)
BridgeLux Blue LED (USA Made)
WaveLength - Red=635-645nm, Blue=455-465nm and Orange=615"
They seem confused.

Weeze,
Weeze,
i ask them what was the right wavelengths on the LEDs.I'll post what they say. like i said, i will not be Flowering for two months or so. i'm just looking at what is out there for now. thanks for all the replys, Tricky

Light Deal!!
Light Deal!!
what do you all think of this light I ask what a two light deal would be on these. It' $260.00 with Free S/H!!! http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320434371271&ssPageName=ADME:X:RTQ:US:1123 Thanks, Tricky

Used oats, half price!
Used oats, half price!
I bought a 2 color "UFO" from tinybear a while back.
The "90W" wasn't.
Hung a meter on it and it just topped 70W.
But, it did veg well.
I no longer needed it so I just sold it for $200.
(With disclosure.)
Good timing, yah?
If you are not picky about power output or UL labels, the price is good.

so i was reading that super lights are outperforming LEDS they have a broader spectrum... check out the spectral graphs on www.portlandled.com... what do you guys think?
A find!
A find!
Screw the graphs!
The rather long article taken from;
"Grow Lights: Separating Fact from Fiction "
On the "ledinfo" page is excellent!
Well worth the long read.
Thanks for the link, Aero.

no problem weezard, im ordering 3 of the 400w units im going to put them over a 4x8 8 tray botanicare aerojet... then i got 3 300w leds im going to do the same with those.. hopefully 2lbs per 4x8 ...i can easily pull 4 with 2 1000w hps no heat would be a blessing
Anybody use one of these UFO's yet? not the same one from tinybear this one actually has some warm white LEDs in the middle all the LEDs are BrideLux brand I'm guess that's a good thing haha not to smart with all the LED stuff but I would like to toss one of these in my CFL cab that's 2.5 sq ft what do you think?

180w UFO ??

It is tricky with a new light for your feedback, Thanks on all info that has been given so far. Areo thanks for the Article : "Grow Lights: Separating Fact from Fiction " it was a good read!! Like i said, my Flowering will Not be going on for six to eight weeks. I am just looking at what LED to go with Thanks, to all Tricky http://cgi.ebay.com/180W-Jumbo-UFO-...emQQptZLH_DefaultDomain_0?hash=item2ea7bd54d5 Thanks tricky

Hi, what do You think about those emitters?
http://www.roithner-laser.com/All_Datasheets/LEDs/LED660-66-16100.pdf
It cost about 70-100 euro per one

Just don't seem right.
Just don't seem right.
And they max at 8.5V. 1.4A
Um, carry the naught,,,
That almost 12W.
For a Radiant flux of 400mw.?!
For How much?!
That's mad!
Ledengin 15W. 660nm.
Forward Voltage (@ IF = 1500mA) VF 11.4 V
17W. eaten.
Radiometric output, 3.2W.
I drive them at 1.25 A and around 10.82V.
An honest 13.5W. dissipation for about $30. USD ea.
I must be missing something here.
