Nope. Find the scaling PPFD of your typical HPS. You'll see what I mean.

Fuck, yeah, man. Ain't no bullshit, either. But you are right, startup is expensive.
What the fuck are you even bitching about? This is a forum, where people converse, and derive information. The information you have is incorrect and I urge you to do your research in order to be properly informed, or risk looking severely retarded.
you're a silly clown. you go from not having a clue about lighting to accusing folks of phony posts Youre as credible as your butt hurt protests are cringe worthy. Only an idiot claims to be "100%" correct" based on fantasy and denial.
You can grow 2.5+ pounds of chronic off 267w of c.o.b.? I find that hard to believe but anything is possible.
What amperage and how many emitters? I get ~850 PPFD from one. 36v, 3500k, 80 CRI, Top Bin CXB3590 driven at 2150mA. I suspect you are driving multiple emitters at like, 700mA and are using some other older or weaker emitter. You definitely don't need 700w for 1000 PPFD.
You ignorance is showing again.. go educate yourself... then come back...or don't!
I will let you know at the conclusion of this grow. I haven't finished one yet under these, but I have never had the plant grow so big in all stages compared to the LED panels I've used, and I have never had a seedling or veg'ing plant push trichomes on fan leaves under those old panels like I am not. The size of the plant from seedling on up is relatively exponentially larger and more rapid under just one of these 89w COBs than it ever was under 2 "450w" panels drawing 206w each. The PPFD and my observations correlate and help me conclude that these COBs in this setup are equivalent to the productivity under a 400-600w HPS.
How can you really say they are the way to go ??? people are getting decent results with cob' tech its not going to stop there look at the stocks ? Cree has leveled off and is dropping could 2018 bring out a better lighting technology ??
Well if we look at our advancements from 10 years ago YES Cree cobs will be the HPS of the led industry
With all the fairy tales and lies we see and here daily Yes even from growers on here claiming unreal yields specially with cobs soon anyone can really say yes its better efficient.. But it lacks in penetration and with that yield more efficient less yield ???
Kinda sounds like a moot point but is it ??? Lets have a look HPS you need AC units cause of the heat ??? well i have grown now for over 35 years consistently and only start indoor growing in end of oct with fresh air in 6 - 8 k rooms no AC needed actually use the heat for my benefit
Point being is claims you need to cool down your room and ventilation there for operating costs are more ???
Well when we look at normal grow room design ventilation / Fresh air is one of the most important parts of any design or properly built grow rooms and even tents have i vents
i can post millions of pictures of heat stressed Cob grows so again another well orchestrated lie
that LED or cob does not produce heat truth is all power sources produce heat if that wast not the case WTF would a person need a heat sink for ??
And last is how tight has a person gone worrying about 1 - 3 dollar savings a month on power cause that is what it really comes down to pennies
From the moment you took your first breath was the moment sometime in the future you will take your last breath
Same thing applies with everything including lights from the moment its turned on its slow path to death is going to happen sooner or later
So which is better well it comes down to what are you growing in a bread box or a green house or a regular room ..
work with what you got learn try new things which means yes even new lighting
But truth is there is really no better LED Cob or HPS find the one that suits you and that is it
Makes me sick when i here Hid destroyer or cob,
is so much better .. its not it never has been its just another light source an what may work good for your situation here one plant grow 1000 watts over 8 pound what is that for GPW anyone ??? you know anyone with them Einstein skills lol
Yup cob destroyer lol View attachment 3805460
Have a great day
I bought my first hid in 1972 ....fluors before that ...So I have some experience with old technology...
I ran our co-op from 96-2015.. All with hid.. well over a thousand plants a year..
I've had my COBs for roughly 2 months..I don't need Einstein
to tell me which is superior... Experience tells me. Oh yeah, light bill is down over $20 per month.. not $3..
Have you run cobs?? Where are the millions of pics of heat stressed plants under cobs? How many heat stress pics under hid can you find? Show me.. convince me..I've run both!! Have you??[/QUOTE
That is the CON with LED's. The technology is like computers, something better and fancier comes out every 6 months. Its always best to do research, every grower faces different situations. So what will suit you best? But in my experience LED's have provided better quality over HID, my yield was slightly less but my next run I will be adding 2 630w DE LEC/CMH to go along with my 3 bar 600w 3590B cree cobs. wish me luckHow can you really say they are the way to go ??? people are getting decent results with cob' tech its not going to stop there look at the stocks ?

bro do your own research. you cant expect folks to assuage your uneducated suspicions.
