400w CXB3070 LED build

Thanks!
Nothing special. I am still experimenting with pot sizes and what not. 2 part FF Ocean Forest soil to 1 part FF Light Warrior medium. I use Technaflora nutrients and feed them once a week with nutes (other than Cal-Mag, which they receive every feeding). I am currently a bit under on Par watt per sq ft, as I am about 9 PAR w/sq ft so we will see how the yield is. Pretty excited to see as it looks like I may get 1gpw or more.
I did grow in multiple size pots to see how the pot size really affected the plants. After side by side comparisons of utilizing 2 gallon, 3 gallon, and 5 gallon pots, I would highly recommend 5 gallon pots even for smaller plants. I flowered my plants at about 1-1.5' tall and the 5 gallon plants are definitely looking heavier even though they all vegged the same time.

Pics will be up tomorrow. Just cut it all down. I am very pleased!!
Completely dry (might gain some weight with humidity packs), stems snapped and cut off, everything trimmed down clean........... Total weight is 488 grams!! That does not include the smokeable trimmings (small buds, closely trimmed sugar leaves) which was another half a pound!!
I am very impressed. I have run 6 HPS grows in this room with a 1000w HPS and the best harvest I had was 21 ounces (same strain, Critical Kush). While I did not get the same yield, I was MUCH more efficient and not that far off. This one yielded about 17.5 ounces @ 1.21g per watt whereas the HPS yielded a best 21 ounces @ .6g per watt. Keep in mind that I was only at about 9 PAR watts per sq ft so I was a little low and still had a fantastic yield IMO.

Looks good. What is the cost on this project and actual wattage? Thanks. I might try it someday.Got them both up and running. First one I screwed up on a bit more than the 2nd. Here is the 2nd. Not bad for my first set and they both fired right up! (most important thing right?) I temporarily wired it up for testing. I need to solder all the connections. I must say, those COB holders kind of suck. They do not hold the COB as well as I thought they would but I got them to work and the wiring is VERY easy with them. These things are BRIGHT! Holy shit batman! I had 7 100w CFL in my kitchen running (26w actual) when I fired up these bad boys 1 at a time and they blew the lighting out of the water. I cant wait to get them on the plants! Hopefully, I can pull 1.25+ GPW which will mean my yield will be right around what I have been with a 1000w HPS in my small area.
Oh, and I put it on a Kill-a-watt. It was pulling 1.83A @ 121v with 223w. Both were identical.
Mine was $325 w/ all parts although prices have come down on some things and also could have done stuff a bit differently. I think $300 is plenty doable for 200w. Considering 200w will probably equal a 400w HPS, its not a bad deal. For a quality HPS setup, it will run you $200 (400w). Now, you can say that you can get HPS setup cheaper and you can, but then you are losing quality. Go cheap on the LED and you can get the cost down too.
Id look at getting away from all that garbage blurple GUOD and build one of these. Far more efficient than anything on the market and its a fun project.
As far as smoke, tried a little early (I know, not cured, its a sin) and its hard to say. There are man more trichs packed inside than HPS. I do believe its a little stronger, to the point where you do not have to smoke as much. The actual high is about the same.

Well, just told Jerry to invoice me. Going with 12 CXB3590, 8 in 3000k and 4 in 5000k. Need a veg light and expanding the grow! Will still be running the 2 lights I built already (no need to toss them just yet!).
Also getting 3 more Meanwell 1400B drivers
Will be doing them semi the same way, except a little larger heatsink and going passive cooling. Plan on running 800w (400w 3070, 400w 3590) in a 5x5 area and running a 3x3 veg on the 200w 5000k. Sadly, I have been down the last few months and still will be till the end of the year. 2016 will be a good year
Should be about $800 for the lighting and another ~$200 for heatsinks. $1000 for 3 lights so slightly cheaper than the last build but much more efficient.

What is the efficiency of the 3070s?
I think thats more my budget right now

Sorry if you've already mentioned this, I scanned all four pages and didn't see it -- How many plants did you run in this 2x5 space?
Did you do the pot size comparison on this run? And do you know how long you vegged for? You mention the height, but you must of topped them a couple of times to even the canopy?
I'm running a 2x4, I've got an 8 COB fixture but was planning on running four for veg (4000/5000k) and six for flower (4000/3000k).
Beautiful grow, by the way.

Does it work to veg with this setup? I don't have anything yet so I'm trying to figure out if I can get away with this for a start to finish.
Edit: I should have phrased my question better: could I use 4 x 3070 3000k dimmed or full power to veg? I'm thinking that building a setup like OP and using a dimmer and adding t5 for veg. I will try that and see how it works.

So is true power 200 watts or 400watts from the wall? i read somewhere dimming doesnt reduce current draw or wattage but im not 100% on this. im not sure whether to go with 2 or 3 lights but i dont want to be drawing more than 2000 watts from the wall with a set lie yours but cut in half kind of.
