Hey So the reason they are not giving you exact brand for each color is because its like a trade secret. they purchase the diodes they choose come from the best manufacturer of that color, like Cree makes the best 450nm Blue and whites,while Osram makes the best reds. The 9 different diodes all come from the top source of that color you can get.Sup man, subbed for this one. Which diodes are in those panels? They are pretty vague on their site
https://www.blackdogled.com/faq_choosing-diodes
"For some of the colors we use, it is very hard to find what the best manufacturer is, but we do not share this information with the public for one solid reason: it is not in our best interest"
This doesnt sit well with me.
how so?
cheers! followed ya on insta, good luck with the grow
Because they have spent $$$$ and tons of time sourcing & perfecting it, they keep it close to the vest.
As far as Leaf Surface Temperature (LST), certain colors(photons) heat the plant up differently than others. Alot of lights on market have alot of wasted energy in areas the plant does not absorb or use as much. This excess of energy used in these areas will heat the plant up, hince the leaf surface being higher and because of this you would normally have to run the ambient temperature of the room cooler to get the LST to the right metabolic rate.
From test and growth rates, cannabis sits best at 88-89 LST, which is why traditionally why people under HID run at 76-78. To be able to achieve the same LST under the BDL, you have to raise temps by as much as 10 degrees. They suggest 84 with out c02 and 88 with c02.
I use a FLIR and can accurately adjust my rooms to the exact temps for my:LST, and often times it is 86-89 in room. This reduces HVAC cost tremendously

So apparently I lost all the photos from the weeks previous and have been trying my best to find everything to share with you guys. I apologize but I do have this grow documented with data and pics from day 1, then jumps to day 37, since it wont let me upload video.
Another heavy defoliation was done at day 21, where the large fan leaves were stripped again. I have video from this but cant post for some reason. It is amazing how fast these plants bounce back and how well they respond to this method.
Here are some pics of day 37.

is it though? it sounds like marketing bollocks, its not hard to find out which diodes are most efficient.
you thought about the latest strips? they would destroy these panels.
or are you just selling black dogs at the mo?

Ppf/w (350-750nm) : 1.336 As per independent tests by chilLed.
Which not really that good.
But the light seems to stack some serious bud though in the right hands. Op has nice numbers for per square foot which is more important for many of us. Also this light has optics, which tend to eat up some light but throw more at the cannopy.
Very good cannopy management, nuthin but tops! Lookin good

You can call it marketing or is it a company trying to make it more difficult for competitors to rip them off. If that is your hold up, sorry to hear. The fact they are telling you they are only using the best of the best isnt good enough, well it is for me. If the fixtures didnt perform like they should, then maybe I would question it, but havent had a problem.
And you saying strips would destroy these panels...strips are 600w fixtures at max, please tell me a strip light that has hit over 3lbs? I do that on the 1000 w series all day.
And yes I sell BDL along with tons of other equipment. I work with BDL closely and believe they are the best LEDs on market from my experience and results I have seen.
To be clear: Lets talk in results here, not theories and what companies claim. Tell me an LED on the market that YOU have seen hit 3lbs+. Results are key and not some on number on a paper an LED company is spewing.
If you are hitting 2lbs in a 4x4 I would say that is great, the results are there, and with the BDL fixtures for the last year working with them and their lights, I havent done anything under 3 with the 1000's. The 800's are hitting consistently over 2+ and have seen as high as 2.9 with a commercial grow that is running organics! Proof is in the pudding brotha, and these fixtures dont lie.
For me, its all about results and all the specs and data from test are only a part of the picture. at the end of the day, i dont care if it is the most efficient light on the market if it can only hit 1lb or 1.5lb in a 4x4. Im a commercial grower looking for production and even if I was at home, I would want something that is going to get me the best possible yields in my space. The name of the game is Grams per sqft. MAX it out. We hit constantly 80-100+ g/sqft on these. So chose to like it or not, but I'll keep my BDL lights over the strips that I have never seen hit weight.

it is 100% marketing because every decent horticultural led manufacturer knows who makes the best, and pretty much everyone here at RIU knows too.
No, no its not good enough. Thats like buying a car on the promise the engine is what they say and not looking for yourself. Do you wanna buy my kit car, mate? its a ferrari under the hood, i promise, $100k its yours.
Send us some pics of your diodes to confirm their words, plenty of peeps here that'll confirm if theyre using the best, man. I'll put money on them lying.
I hit those weights with old quantum boards, seen em hit with old gen cobs. it all means id need a lot less watts of the newer strips to do the same...its not rocket science.
i look forward to seeing ya grow some dank under blurple but there are way better lighting options available for a lot less money. You should try em, they'll blow your mind.

That light is $2600 this has way more output and would save a few hundred dollars https://chilledgrowlights.com/our-products-services/commercial-led-grow-lights/chilled-led-grow-light-1000w

I average 3+ in a 4x8 using 900 watts of Citizen/Cree

I googled the 800, and most of them came up around $1950

With a piss weak efficiency of 1.336 Ppf/w, you do not have to worry about competition ripping it off.
I read the spin speak on their web page and have not been sucked in sorry, so will keep my considerably more efficient QB288V2`s.
Would the dog logo be more appropriate if it was hunched back having a dump position?
