if your looking at a LED Cob then get the same color as @REALSTYLES used in his latest veg light 5600K iirc
covers the spectrum nicely with enuff blue to keep em from running wild on ya
my future led veg build will be a copy of his , he's a advertizer here now

I'll have to search for his veg light all I have seen are the bigger lights with multiple 3590's but not anything veg specific.

Thanks

Ok I see a build thread sort of but you grown anything under it yet?
In a couple of weeks just finishing up flower next week and will be starting a new grow with them and a 3000k 90CRI light 500w each and I also have a 3000k CD bin 500w and I still need to make a 3500 CD light and stay tuned I've got something up my sleeve. Remember when I said I was going to change out a 12'x15' from HPS to leds well it's happening. I'll start the thread when it's all set up. Btw it's gonna be a solar panel assisted grow.

5600 Kelvin would be an interesting thing to try for veg. I love my cool-white and UV T5s, but everyone seems to do dandy with 3500k COBs. I have doubts about stretchy plants under them. I do my first 3-4 weeks of flower under T5 and I keep them really short that way, which I like, for reasons. Once I can grow vert, when we move to a new house, I will grow to the ceiling...but for now, short is good. Sure, I have harvested 5'6" plants in my setup, but I do not prefer it.

@Evil-Mobo - I wonder why lettuce growers don't dim the fucking lights if they are too bright? As in fewer per area or drive them softer? Do they think the mutations are being caused by the amount, or the quality of the light? I'm pretty sure a lot of COB setups are throwing too much light, would love to see a lot more folks doing rigorous PAR readings taken in situ, which is easy for me to say...but yeah, lots of work to do in the field out there in LES-land.

I agree. And I will be doing my own testing soon. I think full power the lights needs to be raised up higher vs thrown on top of the plants. I also believe for veg more cobs dimmed down for better light coverage would do better. I will be testing a 5000K 4 COB veg light soon and we will see it will have a dimmer so I can fuck around with total watts and height from canopy etc.

Lots of ways to skin the light distributing cat. If more sources is your goal, there are plenty of smaller wattage COB LED chips out there to choose from. And they're cheap.

I will soon find out but right now my mission is to find a suitable replacement for my T5's for VEG. I know COB's will work fine for flower, but seed starting and VEG seems to be where most of the controversy and lack of proof is to back anything up. Don't you yourself veg with CMH lights too? Am I going down a path that will just lead to disappointment here?

My 3500K COB LED is fabulous for veg.

EDIT: Best damned light that ever happened to my veg girls, bar none. In case I had left any doubt, Lol

Yo mon - I keep looking, but I haven't been able to find which Meanwell drivers you are using to power your COBs @ 72V. Can you point me to a model number?
Respect!

Much respect my brother!
Now, if you could only tell me what 80 deg lenses you are using, I would be eternally grateful! (I'm thinking you got them from Kingbrite?)
Thanks in advance. Jah, Rastafari!

Yes, that's where they came from. I don't recall the brand.

Meanwell HLG-185H-C700B to drive 4 CXB3590 CD BIN 72V 3500K chips at a time.
Hey bro, I have a couple questions I hope you can help out with. Just trying to get my head around the cob and I think I'm there.

If your using that driver to run 4, does that mean you are supplying 50w to each cob, but the output of the led is roughly 150w?

Second question, how many cobs would I need to flower out a 4x4 wall. Thinking of doing the side/back walls of my tent and make some sort of u shaped frame, that hangs vert and have cobs running down them.

I'm thinking you would want two rows per side?

Hope that makes sense :)

the idea is to run softer to save power & when you compare ratios . the LED puts out more light at the lower rate than the LED does when at full power
ie; you could run at full power but y'd be wasting power with less light to more heat ratios
