See how he has close to the right amount of wattage per sq ft? That has a lot to do with it IMO.

You had a super large area to fill with those 10x V18's (and weren't they sort of spaced out from the canopies?). Next time you'll know exactly what to do differently and what to keep the same. I eagerly await your next grow op.

Will it be under a new thread or the popular DIY one?

Yeah, posting pictures of lights is one thing. Putting up grow journals and results pictures is another. You've gotta hand it to the people with more comprehensive journals showing us what their lights can do.

That 's RIU s 'job' ,anyway ....
My 'job' is to design & built lights ...
And trust me ,I've seen and constantly seeing ,what the fixture's can actually accomplish ,
with their light .

But ain't my 'obligation' to show it to you ,or anyone else .
More or less ,by now ,plenty have seen what & how COBs have the ability grow ..

And most of times ,in DIY ,fixtures of poor cooling schemes and designs ...
Now imagine ,how COBs operate with better cooling ...

Maybe someone buys a light from me and post a grow journal with it ....
I do not care that much ,to be honest ...
I've alredy a long list of wannabe owners & users of my builts ...
Mainly locals ...
It's like a chain reaction ....

One guy visits one of his friend ,who BTW owns a fixture of me ,
and has a tent full of flowers ..
Next morning my phone rings ,for another order ,for another light .....

And ,what I know ?
At least this ...
My country suffers really ,economically ...
Reaaaallyyyy ...
Indescribable by words , everyday situations ...
Still,for some those 500 Euros ,seem to mean not really much ...
They know ,exactly what they are purchasing and of what is capable of..

That's why they never ask even for the slightest discount ,or play some bargain ...
Never .
They empty their pockets,silently ,without taking their eyes off ,from their new "wonder light" ...

At average ,both CXA3070 or VERO 29 ,when driven @ 2.1 A ,
yield about 1 gpw ...


With different stains ,substrates ,growing methods ,nutes ,available space ,ect ...
(& Without burning / frying any of the plants /bud tops ....@ 2.1 A ..)

Almost 99.99% of times ,close to 1 gpw (usually a tad more , i.e. 1.1 gpw ).

So ...
200grms out of 200 W at plug ,most of times ...
Local growers ,like this idea ,very much ,I should say ...
And they are quite few of them ,with my "on hold " list growing larger ,day by day ..
That's why ,I also do not give off lights ,for tests and grow journals.

I know what my builts can actually do.
My customers also know it .
They are plenty enough ,already ...

What actually ,I'm doing in RIU ,
is showing to the public ,
how to make a light ,like the ones I make and sell.

And a good grow ,it takes a good grower above all ,to be done...
A good LED light is a grower's tool ...
I make those particular 'tools' ,as good as possible ,for my taste .

If you would like a " ...more comprehensive journal showing us what their lights can do."
,then my threads & pics should be pretty useful to you.
Built a light like that and see with your own eyes ,the results ....

Cause I'm pretty busy making good lights ,for the 4 to 6 months or so .

If ,from the other hand,you got bored ,seeing pics of metal parts and screws ,
then ,what 's simpler ,than reading another thread and seeing some bud -porn ?


Still,I feel for you ...
I can imagine ,what's 'eating you' ,from inside ...
And ain't good ,whatever that might actually be ...

Cheers,mate .

I intend to start a new journal soon. I will post links in my other threads.

SDS! I appreciate all your sharing. I have learned a ton from you and others here. So much good information in one spot. I already have my next generation of lighting done in my head. lol

My final concern in designing my seed to flower light is the intensity of it in a height limited grow.

I am now looking at PAR wattage figures, but want to make sure that 30 PAR watts is not too much per square foot (especially considering 12" light distance from canopy top). Would I be better off going with numerous Vero 13's or 18's instead of single Vero 29's to reach said watts/sqft when height is considered? Would a single Vero 29 @ 30 watts PAR be more likely to burn than multiple Vero 18's with a total output of 30 watts PAR?

[Edit] With almost twice the distance during veg (18-24" from canopy)

A question for the elders (insert name).

If you could be born with two dicks instead of one, would you choose the two over the one?

Go with Vero 18 (multiple ) if surface ain't an issue ,but height is .( low height situation )
Or if height is not an issue ,but surface is ,go with the Vero 29 .

If no height or surface issues go with multiple Vero 29 s .....

....
"Burn" itself or the plants ?

Im thinking of running two Vero 18's flanked by five 3w 660nm reds on either side. Was considering going with the 5000k v18's. Will the 5000k be TOO blue? Maybe 4000k would be better having more red in the spectrum?

Burn the plants

Vero 29 / CXA3070 AB 3K/80 at 2.1A ,need at least 50 cm (1.6 feet ) distance from the plants .
Anything closer it gets nuked from visible light irradiation !
At 1.4 A ,min. distance drops to about 30 cm ( 1 foot ).

For your case of limited height ,using multiple Veros18 (up to about 500-700 mA max drive ) ,
pretty low distances between light source and top leaf canopy /buds ,can be achieved .
( 0.6 of a foot or 8" ,with Veros 18 driven at ~ 400 mA ..)

Another advantage of this method is the high efficiency of multiple ,low driven diodes ....

Go with the Vero18 s then.


Cheers.

Would you have a recommendation for driving multiple Vero 18s at that level? I was thinking maybe 4 around 400-500 mA. Maybe a 1.05 A driver running 2 Veros in parallel?

If you're going 2x vero18 @ 1.05 A ,then better go with dimmable drivers ...
Still ,I'd prefer 9x veros dimmable from ~300mA up to 700mA .
Very-very versatile ...

(Actually ,I've made a system ,like that ...with Vero 18 3.5K/80 ...
Sold it ...Owner of that system ,is claiming to be the happiest & stoned as brick grower ever ..since ..
Dunno...
Something tells me ,that his claims are not false ..)

9x Dimmable in a 2 foot x 1 foot right?

Cheers.

[Edit] And to clarify I meant 4 total Vero 18's. So you'd recommend 9 total, being dimmable for a 2x1 area

The neutral (4000K) possesses some of the perks of 5000K (blue) and 3000K (red). Between the 5000K and 4000K, I'd pick the 4000K, with the addition of the reds you mentioned.

So you favor the ability, with the dimmer, to start seedlings at lower currents, while progressively raising the current as the ladies age?

But dimmers cost a little extra 'dough' don't they? But they are necessary for certain situations that include height deficiencies, such as small cabs? Otherwise, wouldn't raising the lights, although painstaking, be more of a suitable/feasible option? Please share your experience and reasoning.

I'm sorry guys. I think there was some confusion. SDS, I was asking if I could/should run two Vero 18's through a single driver but wire them in PARALLEL instead of SERIES. Theoretically that would retain the same voltage pull, but would split the current between the two (1050/2=525 each). Do that two times to get a total of four lights running at 525 using a total of two drivers. I'm not sure if LED's work in parallel though.

No.

For that surface ( 2' x 1' / ~61 x 30.5 cm ) ,6 Vero 18 ,dimmable 300-700 mA will be enough .
For driving more than 4 COBs ,I would use an AC/DC main PSU and then one DC/DC constant current driver per COB .

In that way ,the main power supply (AC/DC) could remain remote from grow site ,
while the multiple ' buck ' DC/DC drivers are of small size ( lhalf the size of a box of matches ).
( Recom RCD-48 -700 )

Having multiple AC/DC CC led drivers is more a expensive ,heavier ,bulkier way,
that requires good grounding,isolation and mechanical securing .

So...
Personal POV...

Fixture up to 4 cobs => higher efficiency AC/DC CC drivers .
Fixture with more than 4 cobs => Main AC/DC CV psu & multiple DC/DC CC led drivers.

And AP I guess i see the logic behind both methods, I'm not sure which one works better in practice though.

Same intensity controlled via height or varying intensities limited to a static height. Like you said, one may just come about due to the need to solve a problem (height restrictions).

For my situation since I am in one cabinet with very limited vertical room, I would need to either have separate low-current drivers for veg, or dimming drivers to allow the reduction of current for veg times.
