Well ..I guess I'm not the only one ,feeling this way ,by now ,eh ?

Cheers .

I'm just warming up ,DS....

Nice Try... but these don't have the bands of emitters. You are comparing apples to oranges.

Also there are not two power units just one, in the Dorm Grow. So what do I have to do buy the cheep ali baba one and do a side by side with the Dorm. Let's see some one with the cheap ali baba panel produce what these Dorm Grow lights produced.

Hmm, wonder how many Hans it will take to be on par with what's coming out this 2x2 under Dorm Grow? And how much a piece are they again?

Don't hate the player, hate the game, REF!

Dank, SDS is putting on the Hellas swag, because he ABSOLUTELY knows what he is talking about, although he gets to the point in a round about way.

I would check out his threads to understand how to quantify what makes good LED's.

I read all his shit, because the man knows the #'s inside and out.

SupraSPL, MrFLux, guod, bad k, Positivity, Fran J, hyroot, Mohican, Capt Morgan, GreenGenes, on and on all will lead you down a correct path......... if you want the knowledge you have to read this forum top and bottom.


Get into what makes an LED light source tick, PPFD, ppf and umole/sec........that is my advice. The dorm grow doesn't even offer those, and that should be your 1st Red Flag.....

Check out the Cree CXA 3070 DIY grows, probably the best bang for your buck at the top intensities and efficiency. Bar none. I calculated a 500w version [Real 500w's of output] at around $700 or so....that would start to put your near a 1000w hps....

Read this from top to bottom, LMAO, I am talking about efficiency in LED and you want me to subject my self to inefficiency trying to comb out the treasure among the trash. LMAO.
That is why I started this thread to get to the meat of the matter, just the facts please.
From what you stated you have helped me immensely, the Cree CXA 3070 I will qualify your input that it is the best bang for the buck. I don't mind spending a little more money and get something that is efficient, productive and reliable. At the time I got the Dorm Grow it was the best of the option for the resources and time I had to invest. I do appreciate the wealth of knowledge and those whom have gone before me, but why do I have to rediscover what has been brought out into the light. I'd be happy to when I have a fuller grasp condense it all do to a Cliff Notes type read.

First of all ..
I do not hate anybody,any player ....

( Those I used to hate ,rest in peace ,for long time now ....
What it does not kill me ...Better start running away from me ! )

Secondly ..

I 've a better idea,than " a side by side "...
Just take off the cover of your DormGrow...
Take a few pics of the 'guts' inside and post them here,please.
That will be -more than- enough ,for some of us ,to judge the
"quality" and "originality" of the "Dormgrow" led light ..
Trust me on that one ...



Thirdly ...

G8LED has formulated and tested the ideal color ratio with 8 bands of the color spectrum including Infrared (IR), Ultraviolet plus 6000K white. G8LED lights come with our stellar Customer Service and 2 Year warranty serviced directly by us. We make customer service our #1 priority. Make the smart investment for your indoor growing hobby or business with a genuine G8LED indoor growlight. Power Cord (Available in US, UK, EU, AU) depending on your shipping address. Hanging wires included. No ballast needed. Upgrade your grow room and Grow Green with G8LED Technology!​

This is what drew me not knowing much about LEDs at the time I wanted to ensure I could reach the service department, talk to someone who speaks English and get great customer service. I have one had to return one thing damaged in shipping would not power on and it did not cost me anything, they provide discounts as well and I have used those to save some money. The lights I do have are going on two years of use without issues. Considering the horror stories of the other panels going out and being problematic, I am sure of I could done worse, but I am not convinced yet for seeing is believing that I could of done that much better.

I can do that take pics and show them to you, but you need to read the ali baba site again, in there sales description it says 8 band color, no mention IR or Ultraviolet?

In the technical specs just list two colors red\blue.

Therefore I say they aren't the same or you shouldn't use something as comparison that has two different descriptions of the band of colors used.

There's not any UV or IR ,in your DormGrow panel...
It's already tested ...
Better check here


When they say that they provide "custom orders" ...
They can put/install (almost) whatever (cheapo) led ,you'll ask them to put/install ...
Along with dimming,daisy chain sockets,lenses,bluetooth,wifi and who knows what else ....
It is actually very easy ...And cheap ...
Still,there's no UV or IR ,in that panel of yours ...

 

[stardustsailor]

For example ..
Check the ....

" Heliospectum "....
aka
Matrix S600
aka
LeadZeal ..



The chinese version of a famous swedish-brand led lights ...

For only US $200 - 400 / Piece

EraserHead "Not a bad specturm and has IR"

DankSwag

Actually is not a bad spectrum,at all ..
Under one condition...
That the irradiance will not be over a certain limit ...
If so ..
Then....

That kind of spectrum ,it will need about 6 to 8 hours to burn a hole ,right through the leaf canopy ....


..................
Where's that output from IR leds ?


The only IR i see ,is the 'tail-end ' from the (really ' narrow' ) 660 nm red leds ....
????

Even Cool White leds ,have more IR power than this ....

SDS,

So if this panel isn't all they advertise I give you that could be. However how do you explain the results? If its efficient GPW used then why the exhortation to spend more on an apache or area51? What am I missing I understand efficiency can be rated in different ways but when it comes to the bottom line isn't GPW the final number in arbitration?

DankSwag

 

[spazatak]

DANK... SDS knows more about lights and tech in LED than just about anyone on here... take his word for it...

although this thread has been fun to read

Now ...
Now we're getting somewhere ...

This is my problem here ...

I can't explain the results !

No...GPW ,means nothing ...
Grams per power units ?
Totally relative and abstract "unit" ....


The grams per kWh
(mass produced per energy spend )
looks like a better unit ....
While ,still it can not be used to compare results from different growers and strain genes ..


Your grow remains a mystery to me ...
( I've already told you..You might be one of the lucky "greenhand " ones ...
Just attending to your plants ,makes them grow like crazy ...
Dunno .....
Care to note down some other 'features" of your grow ?
(ferts/nutes,temps...etc ...)

Still that is one of the most amazing led grows I've ever seen .
Trully speaking .

Cheers.

[FranJan]

Is there any possibility that Dank has a promotional model that's actually made with Blue Bridgelux and Red Epistars? Was it a lot of panels that were made this way in order to convince people to buy them? Was it one of those crazy Chinese Commie factory BS things and the only diodes available were good ones for other manufacturer's devices and they were co-opted for a short while? Cause I'm a little confused everyone. Has Dank stumbled onto some magic formula? Or is there a simpler explanation?

OK I gotta go back to the reclamation center and find my A300. Later.

Pix Danks. Pix would be great.

SDS,

GPW, Grams per Watts used? What do I divide my total weight into to determine how well the lights performed.
Could it be the additional red 12 watt bulbs? The only CO2 would be from attending plants during pruning and watering? The water used was city water set out to evaporate of chlorine. The temps and humidity kept in acceptable ranges. The plants were clones from my mothers and were cloned using aloe gel wrapped around stems and rooted under 2 24 watt 6500K CFL lights until rooted and new growth developed. Then transferred from solo cups once roots established into 2 gal organic soil mix, my recipe. It is something I am planning to sell at my Organic Farm I am starting up. During transplant used Xtreme Gardening Mycos 30 6-4-4.

After that just watering and pruning until harvest. Perhaps the fact they spent their entire veg and flower under the same lights once transplanted?

Fran,You're amazing ...
In fact ,what'you've just claimed ,has plenty of possibilities to be true ...

Still...~250 Watts ?

Those plants look like they 've been growing under ( at least ) a 600 W HPS ...

Am I so wrong ? Are my eyes deceiving me that much ?

( Please say no ...
I have to go to the dentist ...I can 't afford a visit to an optician,too..

Haven't passed it up, perhaps you need to read again where I posted, just harvested, waiting till flowers are dry to provide total weight.

If you can wait till this weekend for numbers then you won't have to ask again.

Oh Yeah hoping to get the lab to test it.

I read it when you posted it...I know that you have no idea what the weight will be.
But you keep saying "what will produce what this dorm grow does"....And that is why I keep asking what has it produced????
