...All Things Vero...

Would you consider buying a VERO after reading through some of the posts?

i am pulling my hair out over here as i have bought some cen 100-36 ballasts..and now i can't decide if i should buy the vero 29 90 CRI, or wait for the 80 CRi to come back into stock, from what i have read the 80 CRI get a ~1200Lm boost compared to its 90CRi counterpart.

anyyyyy advice would be greatly appreciated.
 
on the CRI number, I get confused, do I want 70 80 or 90&(95)? will be using 3000K and 5000K's?
I may have ordered the wrong 5K's, just use them for garage lighting then. I found some 5K 70's
if I need to replace, always moving in spiraling larger circles.

So I'm very seriously considering upgrading my veg lights to some vero based lamps from opticlighting.

I noticed they offer 3 different spectrums. I was going to pick up two 360w units for a 5x5 tent. I was considering mixing up the spectrum a bit but I was wondering how others experience is with these spectrums at various points in the growth cycle.

At this point it seems like the 5K spectrum and 4k is best suited for veg. Perhaps the 4k if you had to choose one, but I'm picking up two lights and there will be pretty significant overlap of the spectrum.

I do want to use them to flower a bit too, but only the odd autoflowering plant if I find the space which is hardly certain.

Would be curious to know if anyone has flowered under the 4k's exclusively and also vegged and how they performed overall.

Buds like this may look impressive, but in practice may not be as great as they look. From a pair of 600 HPS:
dsc06100a-jpg.2949571

Large and impressive but in reality they were fluffy and farmy and worked out to .57 gpw. There was some dreading, white pistils etc. I call it a sloppy finish because the new calyxs will not have mature trichs. Not what I would consider top shelf, although hopefully the LEC would increase potency and terpenes to some extent it still has the 825nm infrared peak.

This Ace of Spades cutting grown under HPS in the first pic. It came out nice, no complaints. But the same cutting run under LED in the second pic was truly top shelf and a great response from testers. In the HPS setup it consistently turned out .35 gpw and in that early LED setup .93 gpw. The LED buds are denser and danker. Actually some indica doms can get so dense that you have to watch out for white mold in the center of buds even in dry indoor conditions, even with a 56 day finish.

Sorry for the off-topic but it makes the point, I had the choice between LED and HID and the data point I have to add, LED kills it. And that was before COBs

I have chosen the Mean Well HLG-185H-C1050B and i intend to plug 4 Vero29 on it. For the HS i will try with this one: http://www.tme.eu/fr/details/rad-a6023_300/radiateurs/#
I prefer avoiding cheap ebay driver for my first setup, i choose a known reliable brand.

I went with the C1400B version of that driver for my first light (4 cxb3070s). They are awesome and you will love it.

This time around, I am just going for a small 100w light that I can use to veg in a spare closet when needed. Since this probably won't be a full time light, I just wanted to see how cheap I could go! We'll see how it turns out.
 
The only benefit of high CRI would be heavy deep red in the décor (Is that even offered in Vero V2?) but the consensus is the loss of efficacy isn't worth it.

Looking at the graph, it seems like the amount of blue in the 3000K is down...

Lower CRI is - in the case of Veros - probably better for growing purposes. Been answered so many times already. Get yourself familiar with the search function lol

I was utilizing the umol/J table you provided us (thank you) earlier today and it would seem that the more the red, the higher the value of the umol/J. I don't know it but are those numbers off the table you provided the correction factors that one could use if they were to perform lab testing with say an Apogee sensor?

Justtt wondering.

up did some research on the CRi and higher CRI is better for veg and lower CRI is better for flowring. the change in CRi gives more power to different wavelengths.

80 CRI sounds like the middle ground. I wouldn't go any higher. I'm tempted to play around with the 70 CRI at some point in the near future.
 
There seems to be a give and take to it and I have no objective opinions on the matter. I've read that the 90+ CRI is less effective (but are there objective grows proving it?). What I do know is that it's about 20% less light!

70 or 80 will be a moot point for a lot of people, unless considering 4000K CXBs. For warmer Cree and Bridgelux, the choice is 80 or 90.

That said, the high CRI spectral distribution is "beautiful".

High cri boosts the blue spectrum hence why it has lower lumens, and looks brighter visually, but the lower cri boosts the red spectrum (600nm to 700nm) hence why it has higher lumens, a hortilux super hps has a cri of 25!, so have fun man! Just be ready to experience so crazy lumen output.

You got it mixed somehow.

And this, too.

I totally agree. Higher CRI LEDs have relatively higher output in (deep) red. The thing is that in absolute numbers, their low CRI counterparts do have the same amount of (deep) red and a boost in all other wavelengths.

Not really sure what you consider deep red, 640-680nm sounds ok?
Then Vero décor 3000K has only 8.5% more of such light than Vero 3000K 80CRI and 10% less than Vero 3000K 80CRI v2.
V18 size, watt for watt, absolute.

And a detail.

I'm not trying to say that some extra deep red is not beneficial. Vero décor just isn't a good choice to add it.

What would be the recommended distance from canopy for ~460 watts of Vero power? 4 Vero29 2.0 (~280w) 4 Vero 18 1.2 (~130w) 1 Vero29 1.2 (50w).

Right now I have it at about ~16 inches from the canopy and the temperature is hitting 91 :-(

Little too warm for my tastes. This is in a 3x3 Gorilla tent with a 4" carbon filter/inline fan cranked all the way up, and a small intake fan.
