This video should put to rest several led misconceptions. Enjoy!

Check out my thread to see how well a 3 yo ufo 90 is doing when combined with a few missing nms using low watt leds

So that video does not give total disclosure though bro... Are the ufo's being used totally and completely 630's and 660's?? Are there any other spectra mixed in? I would like to have all the information before drawing a conclusion........I'm not trying to be a prick here....just want all the facts first..I've never seen a factory made light with just one light wave unless it was specifically ordered and again, that is not indicated...

There are 3 sides to every story.. side A, side B and then the truth.........

Sorry to rain on your parade but.........as I said,,, give me full and total disclosure about every aspect and facet of the test, then and only then will I agree with the results.

<add edit>............gotten off the comments on that page...
It was a triband led with 7:1:1 ratio of red, blue, orange.
We are not going to disclose the manufacturer, as it was stated before, as we did the research, and chose the best one as our main product we distribute.

Sounds like skewed and bias data if you ask me....

Let's punch holes in the vid.

1) Scientific method.
Well, as you know I grow sog. All my plants come from the same very consistent mom or her progeny. Much to my dismay, the clones don't all come out the same on any given run.
The difference in the 4 plants are well within the standard deviation that I experience in my grows.
A real test would have at least 10 plants per light and done at least 3 or 4 times to get a reasonable sample.

2) What does a plant do.
A plant takes in chemicals and light and uses the light for whatever type and properties of energy it needs and uses that energy to create new chemicals/molecules.

What this proves to me is that a tomato plant can take a very narrow bandwidth of light and derive different energy characteristics from that very narrow bans of light,
and maybe do as well as a led party light.

Assuming that the above is true, there is a price to be payed.
If the plant needs say, blue light. The blue light energy characteristic can be derived though resonance and mixing frequencies. (big losses here)
The price to be payed is excess heat and harmonic/resonant losses.
What this means is that the plant has to take in much more red energy and convert that to something else most of the time.
The excess heat would cause excess transpiration as well as extra stress on the vascular system.

One could argue that the early flowering is a sign of stress, to say "I better hurry up".

Just smoked a fatty and couldn't help my self.

And just to qualify this. "I could be totally wrong"

Okay, so there is a single spectrum ufo out there. In no way does that video indicate this is the product used in their 'study'.

I'm not going to do this, with you or anyone... I think it's great that you believe that video...I really do.

I for one do not....why? If I take that video as true, then I would have to take any other video a company/retailer or anyone else with a 'horse in the race' as true also. Hmmm, I wonder if HGL or AdvancedLED have changed or altered video 'evidence' to aide their objectives which are more sales of their own products? ( I use these two retailers only because they are the only two which come to mind first. I am not trying to single them out in any way)
God Forbid, I get accosted for displaying my opinion.

No, my friend, I will not do that. I have a little too much respect for the work you are doing. When I see an objective, scientific study done by someone who has nothing to prove ....or...........sell.....I will then believe the study. Until then, I believe I am still fully entitled to my opinion.

Good Luck

What was important to me was verifying that 660 does not help. My personal experience is, in fact it retards flowering (1/8 4ft HO T5s), and from the video, looks like it retards veg, too.

Personally, i too have doubts that actinic spectrums will grow well. My own 3 yo ufo 90 is 9:1 R+ B with 2-3 R bands covered. I never had much success with it alone, but when supplemented with missing mid-bands it rocks hard.

Now there is something we both agree on.... I personally think that anyone who is going to work on a DIY must include some sort of white light into the fray, whether it be CW, NW, WW....just has to be there... Too much evidence points towards it being a completely beneficial and much more so.....a necessary addition.

Now, whether the 630's are better than the 660's...again, I don't believe that the 660's (and higher to 680's) can work without the combined assistance of a far red or IR.. I am referring to the Emmerson effect so I will try a light with 660's but will also include the 730's as well.....

All I can do is try and when the results come in, if I was wrong,...oh well, I was wrong and I will admit as much...but I just gotta try....

Have to wait until the holiday is over in China for my shipment...yes,, I opted to test and sample with the 'el-cheapo' variety..:-)

Good Luck
