If they picked the right spectrum for their 3590, they would have enough blue and red in them to be full spectrum growable. I.e. A 3000k/3500k/4000k

Sorry maybe a stuppit question.
But what do change when you dim your leds?
It's the voltage right?
So maybe then a gadget like this would be cool as well..

Holy shit those are expensive. The heatsinks he uses are about $12. The citizens are $12-$14, and that meanwell driver is another $20. Add a solderless holder for $2 and a power chord for $4 and you are into your light for a whopping $52. I don't see how he is still in business.

Send me a pm my friend
What's up everyone. I'm new to using cobs and really would like some help on how high from the plants I need them? When I switched cfls out with my cobs, I might have stunted them and taking me some time to find the sweet spot for them. Someone told me 18" and I have it at only 25watts total.
I am using 4 CLU048 1212 80cri with 185h 1400 driver.
So I have them at about 18 to 20" away and total of 25 watts. Turned it down alot. How far away would I need them to be able to turn the light up to about 50 to 60watts?

In a lot of ways, watts are watt and 25 isn't many watts - - What size plants are these? Are they in veg or flower?

Thanks but I don't think he's in Canada. There is a new shop that specializes in COB components so it might be the guy I'm looking for.

I was wondering if I could a little bit of help with a Cob build. I'm working with 80"x80". I would like to build an array consisting of a full cycle grow (3500k 90 cri? Or am I wrong)would like best of both worlds I would like to push about the same watts as my current setup so 600 maybe 800.
Most likely 4 plants max maybe more but doubtful.

You just specified exactly what I need as well. Very interested in the responses.

It all depends on your budget what are you willing to spend?

I would like to keep it around 500-600 but I do have 1000 cushion

Cool now there are mixture of ways you can run cob setups.
Do you want just cob leds or a mix between cob leds and qb boards?
You can run a set of 12 vero 29se with a mixture of 35k 80cri and 4K 80 cri. With 2 drivers a 480-1750 and a 320-1750 for a total of 756watts. 63watts per chip @1750ma. Total cost for chips and driver including misc parts that you will need like thermal compound, lenses, heat sinks etc. roughly 820$. That will not include your aluminum substrate.

Or you can do a mixture of 4K hlg quantum boards with a mix of 35k cob leds.
600-800 watts for 44.4 square feet? If you are getting good yields out of 12-18 watts per square feet, I wouldn't change a thing. That's not a lot of light.

You can get twice the wattage per square foot. Twice the yield and lower cost of electricity maybe even cut out the portable ac and just use fans. Why not? Also your on a full spectrum as opposed to just a low nanometer red on a hps. Oh and you don't have to switch bulbs.
