Hey Nachoo
I also saw this vid / company and posted a while ago about their Violet based leds, like the normal phosphor white leds but much wider spectrum, starts from 300-something and goes really far into the far-red. It doesnt look very efficient, lum/watt is poor but could be allright for supplementary light, instead of adding UV and far red separtely.
Also read thru some of your grows a few days ago; very nice setup with some really nice genetics. I like how you experiment with flowering times and spectrum for quicker flowering and yield increase. You mentioned somewhere youre in the Pyrenees, ets Catalan? I have friends growing in Bergueda.

I am in the aragonese Central Pyrenees
I know the catalán also, they pretty close Regarding the leds... Far red levels are ok in a normal 3000 K led...and to be useful must be used in separate leds not in a mixed spectrum..and regarding the violet spectrum zone...you could use good Samsung last generation leds or cree, vero ,citizen cobs..around 3000-4000 K and add some actinics or good blue/uva leds...this will be much more efficient than use the same watts with only this violet based leds....but anyway..I love the spectrum they give

I'd like to just buy the heat sink. I'd slap a Citi CLU-058 3636 on it and get 36K lumens for half the power their chip uses.Ohhh man, I came here just to post this...

I disagree that green is undesireable. And besides - their spectrum is heavier in green and cyan.

Where did he say undesirable or that he didn't want green???

What would be your thoughts on having some of the smaller Yuji chips put on cob sized pcb's or larger boards?
Do you see a value in their spd?

"but since we dont want (too much) green"
Maybe not in those exact words, but the inference from that statement is that green is not desirable - or less desirable.

It's just another way to do things. I have always said that the day I can supplement and not loose radiant efficiency I will. A few of the newer reds in the last year have made it an option. SPD(of our mix) is good, but the photons and energy are better and why to do it. Problem is the whites in the same package size usually aren't "up to par" with other packages like COB's. It's always a balance of cost to performance, but still can make them cheaper than lots of other options, and getting better prices.
As far as tightly packed vs spread out board...is that what you're asking?
Again, another way to do things...each has it's pro's and con's...build wise and performance wise. In the end it always comes down to photons and getting them to the plants. A well built system implementing either light engine design, will do the same job esstially.
Limiting factors may force one or the other, but with out limitations...photons are photons.
No, not that is not what he said, or implied. Nor was it even in repose to you. So just wondering why you felt the need to ASSume and comment on what he was saying, and not even present any counter information.
So to give you some context on what you're commenting on, here is what he was responding too...
So now that you actually have the context of the situation(available by reading the whole thread)...rethink your Assumptions and tell us what he is actually saying about green and its role in the situation he was responding to???
As well as for the rest of us that don't Assume...tell us what is "too much" green?? He never defined any numbers....but you Assumed quite a bit, so how much is too much. How much is not enough?? How much was "he implying"? You see where I am going with this?
Not trying to be a dick...I call @CobKits out all the time too for his over statements("sphere test"...or "testing in a sphere" ). This forum is ruined enough, a simple "my bad", was the appropriate response....but hey, keep backpedaling if that's your thing.
Long story short....DONT ASSume!

1. Cobkits did not quote the post he was replying to. So any claim of such "context" is an assumption on your part. In light of the rest of this screed, that makes you a hypocrite.
2. Cobkits is a big boy. If I misconstrued his meaning he is capable of informing me of that himself. If he does not wish to do so, that is his prerogative. Either way, your intervention on his behalf is not needed.
3. In my experience when someone says "not trying to be a dick" that's usually exactly what they are being - and intentionally so.
4. Who appointed you the assumption police?
So, to quote the great Jackie Gleason from a movie that's probably from before your time - "Do the letters F O mean anything to you?"

you misconstrued it
i never said green was undesirable, i meant to say making comparisons of the photosynthetic effectiveness of a spectrum based on a green-centric measurement standard is erroneous.

The guys at Yuji are cool. The problem with the VTC series is the package material. The lifespan of those are terrible. That said they are working with a different material and also working on a violet based 3030. I'd like to put one or two in each string once they get the bugs worked out.

Ohhh...I hit your sweet spot of insecurity. And your still backpedaling...why can't you just be a big boy and actually act like a normal human being.
You do realize that you are the one that is wrong. You are the one that just got called out and are still trying to make someone else say what they NEVER did, just because you can't get over yourself to say" ya, I was being a want to be know it all"...aka RIU police your attempting to deflect on me. Focus on yourself and the fact that you are wrong and won't admit it even when called on it multiple times.
So here it is straight from him how wrong you are and how exactly right I was.VVVVVV
And anyone would be if they actually read in context. But hey...I'm just the one that said it EXCTLY for what it was. Keep back peddling...and stop trying to kill the messenger...really not helping your case. Calling names instead of actually supporting anything you said. Notice how there is not one number of figure supporting "too much green" that you ASSumed about. SO smart guy...give us some actual figure instead of stopping your feet and say..."no, you are".
So anyways dude...get the fuck out of your fantasy land you have in your head. This is reality and your wrong...man up.

Ohh look at that...still mad you got called out. And still not one supporting figure, paper, or citation for what is the acceptable amount of green. Because you had and still have no answer...you only had the need to comment out of context.
I'm done...my point has been proven. I haven't had to resort to name calling because of lack support for my claim...just stuck to the facts of the situation. Sorry that bothers you so much that you have to lash out in emotion instead of facts and information.
