...All Things Vero...

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.

I'd take down a fixture or two.... ~51W per square feet with Vero is overkill... especially when temperatures are so high.



When running Vero 18s at 30W (1050mA), I never allow canopy and LES to be any closer than 8 inches.

I run the same emitters at same amps, I've found 8" is the sweet spot too.

I have V29s at .7 amps, can get those as close as 4 inches.

The heck, there is a graph literally two posts above Yours. Use your little Clicky button.

Nah you don't understand what that graph means and now you're being arrogant. Little hint: the curves are not relative to each other.

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.

So far, the only pics I've see using Optic Lighting's COB panels were in this thread.

The results are encouraging, even if the plants were harvested a little early, IMO.
After looking over the efficiency spreadsheet for Vero, and comparing it to Optic's specs, it would appear that Optic's Vero 29 5k panels are their most efficient models, by at least 3-4%.
I'm considering picking up some of Optic's lights, to upgrade my grow, as well.

Patience, better light fixtures are on the way.

Got the power of the sun goin in there for sure, haha! Moved the light way up, 2' away from the canopy, I'm sure the temperatures will still get to the mid 80's. Hopefully moving the fixture a little closer to the exhaust will help pull some of the heat it creates out.

I've been hearing that since last October, and I'm upgrading no later than July, so they'd better hurry up.

Lol, you're in luck then.

I hope so, but we'll see what happens.


*EDIT*
Optic Lighting just updated the PAR numbers, and coverage areas, for all the lamps on their site. This new data is without the lenses on.

Vero 29 500w
Previously (lenses on), 4x3 core coverage area, 2,000 umol @ 16"
Now (lenses off), 5x4 core coverage area, 1,600 umol @ 16"

lol i suuuure am, i def read that wrong. whoops.

Wondering if i have my lamp too close. Im noticing that buds more distant from the cobs are frostier than those close to the cobs. Although i dont observe any bleaching. Pistils at top of plant, close to cob, are perfectly white.

Ive got the lenses off and and the closest distance is about 8".

I think you may be right about having it too close. Listen to your plants, they tell us all we need to know.

Ive been juggling it up n dwn since i got it. Since ive seen no sign of distress im not getting a clear signal on how the gals like it. Ill lift it up some tmwr and post pics moday or tues for some feedback.

Sample popcorn from that earlier harvest are very,very nice with just a prelim drying.

Do you know your canopy temps? Mine got pretty toasty today and the plants didn't seem bothered, but I suspect there may be damage that we cannot see, such as 'terpenes' being burnt, so to speak. Might be the answer to the closer buds being less frosty?

Currently trying to find the sweet spot for my Behemoth in a small tent lol.

Edit: foxtailing late in flower is a symptom of high canopy temps right?

Foxtailing can be caused by hightemps for sure.

Ive not checked canopy temps. my room is high temp 81 and very breezy. ive got luxury levely of air exchange.

Ill take a reading soon and post the info along w a photo update.

 

[jtizzle]

Does anyone have any photos of diy cobs growing product like the latter runs in this video?

Holy shit batman. I have never in my life seen such sites.
All I can say is fuckn wow man. Pro level.

Let's get ready to assemble !



That's so much light that my phone camera can't handle it

The only problem I see with that superb Umol output is that with a fixture's lights bound to a 18" x 12" area, you really don't get much of a great spread, especially in a 20ft square room.

Also, 16" seems awefully close for Vero 29s to be driven so hard (2.8A).

The build was very easy and accessible to anyone, don't be scared to give it a try. If i can do it, everybody can :

This is one of many things that is so great about the large COB LEDs, they are simply a matter of matching up COB, Power Supply, and heatsink and then not messing up the tiny amount of wiring that needs to be done. Anyone should be able to do it considering there are so many combinations of parts that people have already posted!
