@HydroRed Did you see my post from yday? i asked which strains you've chosen to grow out - I think I've made a mistake in my "choosings" :?

How many cxb 3070 and what was the grow space? Or do you know the PPFD?
The 16 cxb 3590 in a 5x5 are at 1400ma so 50 watts each cob. 800watts in a 5x5. So I should kill it. But I don't expect professional gpw because it'll be my 3rd grow. I'd be super happy with 1.3gpw which should be doable unless my strains suck.
I used 3 3070s in a 2ft by 1 ft by 5 ft cabinet grow I am a small PU MMJ closet grower.I don't worry about PPFD. I look at radiant power and spectrum. I understand quantum theory but do not enjoy debating it. as i said before I grow plants in soil. not on chock boards.I get 0.8 GPW with my T5s and thats more than enough to keep the medicine bowl filled

Where can I get some of these already built? How much more would it cost me compared to what I was going with, and how much better would the yield at the end be? I know you can't be exact because of other variables, but for example 10%-25% more?? Or is is purely based off efficientness, and not so much on the yield part. But more so energy consumed, and less light-spread
Dude i gave you the name of the company. try your search engine

They're still charging alot, but its a reasonable price for the exact same thing with 3590's instead of the 3070's... What do I get from paying the extra $250? A big sign on my forehead stating "Retard" I assume?
4 cxb 3590@200w will makes about 20% more light than 4 cxb [email protected] yeah timber.....

I dont know about cxb3590's making 20% more light, but they do run a bit more efficient than the BB bin cxb3070's...and not by a huge margin.
Im currently using 8 cxb3070's BB bin with 2 Meanwell 185 1400mA drivers. If I were to add another 200W bar it would be equivelent to my 1000W HPS
a dispensary up here switched from HIDs to high end leds. they saw no increase in yield but a substantial decrease in cooling cost for a large commercial grow. the best leds have a hard time competing with HIDs and when experienced growers are pulling 1gpw with HIDs I find it difficult to believe that LEDs would be doing that much better.that industry has been plagued with exaggerated claims for the beginning. different lights do require different growing styles.and people that don't know how to grow with HIDs may get lucky with LEDs but I find it hard to believe that an expensive light can make that much difference.there have been dramatic improvements in HIDs and fluorescent in the past few years. the new CMH bulbs have a great spectrum and come very close to matching the mccree curve. of course if I spent $2000 to replace a $200 dollars light.I would rather claim that I made a good choice then admit that I could have done just as well with a cheaper light if I had just learned how to grow
This would only make sense for them to do this as an "upgrade" if they matched light output to footprint of the HID's they were replacing. 600W of COB LED is comparable to a 1000W HID. They should have seen a serious reduction in power consumption just on the lights alone. Plus the led run cooler so they would also see a reduction of cooling costs like you mentioned. Doesnt make any sense to replace a 1000W hid light with 1000W of COB LED only to experience savings on cooling costs. Its just not economical for larger grows to do it since it has the upfront cost and the waiting period to get back in the black with savings from the efficiency upgrade. There is too much info out there to deny that CREE COB LED's grow great weed at a fraction of the cost for operation and can supply proper amounts of light comparable to HID at a fraction of the operating cost.
This is why I lead with "without getting into it too much" a few posts back haha

Ive run quite a few strains, but never picked a strain solely on the purpose of growing out a sog. I have plant count maximums so I dont do large plant count sog. I can recommend that you stick with hybrids for sog. Indicas grow short and bushy as to where sativas grow tall. Considering you dont have much restriction for headspace in your tent, I think you could run whatever you wanted but believe you would do best with a hybrid. Harden the clones off in the light for a few days then throw em right into flower. Anything with any mentionable percentile of sativa in it will stretch the first 2 - even 3 weeks or so of flower. You'll be good with whatever you already have ordered. If I were to run a 36 plant sog in a 4x4 I would go with a 50/50 hybrid or a sativa dom and take the extra week of flower vs the 2 weeks veg time a heavy indica dom would likely need before the flip. Hope this makes sense.

Gotcha, alright. SSDD has I believe 4-5 different phenotypes, hopefully I can find a nice sativa Dom. If not which would you recommend? Wonder Woman is supposed to be good for SOG, found that from growweedeasy, might be wrong :s

Cxb 3590 from 3070 would be a gainof about 45.4% to 56.3% efficiency (24% more light/W) at 50 w each cob.
I didnt think the difference was that considerable since the binning was determined at 2400mA @85*C for the CXB3590's
and 1900mA @ 85*C for the same bin CXB3070's (which both of these were referenced at BB bins at 3500K on the cree data sheets). The 3590s were binned at a higher mA to achieve the numbers it has listed in the cree data sheet. I dont want you to think I'm trying to ague, I certainly dont want to give that impression but more to understand and learn something about this. Im relatively new to COB LED's.

well, it is a reasonably priced kit that takes most of the DIY gone bad out of it, BUT, some DIY leaders are beginning to see that supplementing CoBs with key spectrum discrete monos pays huge dividends

do you even now the difference between 3070s and 3590s, or are you just a follower?

I'll let you decide whether you should tattoo Retard on your forehead.

A 630w CMH would blow away that 1000w easily. And cost less on power bill. If your buying new equipment now a days, standard HID lighting is outdated. It is not the best choice IMO.

They make inner and outer dimension flood trays, so poeple can fit them in tents. Look into it. Your local hydroshop should know about them. HydroFarm OD trays.
